What’s the difference between liquid and powder laundry detergent? It’s not just the obvious

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> When shopping for a laundry detergent, the array of choices is baffling. All of the products will likely get your laundry somewhat cleaner. But what gets the best outcome for your clothes and your budget? Do you want whiter whites? Do you need enzymes? And what’s the difference between a powder and liquid detergent? As is often the case, knowing more about the chemistry involved will help you answer those questions. <h2>What is a detergent?</h2> The active ingredients in both laundry powders and liquids are “surfactants”, also known as detergents (hence the product name). These are typically charged or “ionic” molecules that have two distinct parts to their structure. One part interacts well with water and the other interacts with oils. This useful property allows surfactants to lift grease and grime from fabrics and suspend it in the water. Surfactants can also form bubbles. Metal salts dissolved in your water can limit the performance of the surfactants. So-called hard water contains lots of dissolved calcium and magnesium salts which can readily form soap scum. Modern laundry detergents therefore contain phosphates, water softeners and other metal “sequestrants” to stop the formation of soap scum. Phosphates can cause algal blooms in fresh water environments. This is why modern detergent formulations <a href="https://accord.asn.au/sustainability/phosphorus-standard/">contain smaller amounts of phosphates</a>. Many products also contain optical brighteners. These chemicals absorb ultraviolet light and release blue light, which provides the “whiter white” or “brighter colour” phenomenon. Laundry detergents typically contain fragrances. These aren’t essential to the chemistry of cleaning, but give the impression the clothes are fresh. Lastly, some laundry detergents contain enzymes – more on those later. <h2>What’s in laundry powder?</h2> While detergents and ingredients to avoid soap scum are the most important components, they aren’t the most abundant. The main ingredients in powders are salts (like sodium sulfate) that add bulk and stop the powder from clumping. Another common salt added to laundry powders is sodium carbonate, also known as washing soda. Washing soda (a chemical cousin of <a href="https://theconversation.com/vinegar-and-baking-soda-a-cleaning-hack-or-just-a-bunch-of-fizz-225177">baking soda</a>) helps to chemically modify grease and grime so they dissolve in water. Laundry powders also frequently contain oxidising agents like sodium percarbonate. This is a stable combination of washing soda and hydrogen peroxide. An additive known as tetraacetylethylenediamine activates the percarbonate to give a mild bleaching effect. Chemically, powders have an advantage – their components can be formulated and mixed but kept separate in a solid form. (You can usually see different types of granules in your laundry powder.) <h2>What’s in laundry liquid?</h2> The main ingredient of laundry liquid is water. The remaining ingredients have to be carefully considered. They must be stable in the bottle and then work together in the wash. These include similar ingredients to the powders, such as alkaline salts, metal sequestrants, water softeners and surfactants. The surfactants in liquid products are often listed as “ionic” (charged) and “non-ionic” (non-charged). Non-ionic surfactants can be liquid by default, which makes them inappropriate for powdered formulations. Non-ionic surfactants are good at suspending oils in water and don’t form soap scum. Liquid detergents also contain preservatives to prevent the growth of microbes spoiling the mixture. There are also microbial implications for inside the washing machine. Liquid products can’t contain the peroxides (mild bleaching agents) found in powdered products. Peroxides kill microbes. The absence of peroxides in liquid detergents makes it more likely for <a href="https://www.mdpi.com/1420-3049/27/1/195#B15-molecules-27-00195">mould biofilms to form</a> in the machine and for bacteria to be transferred between items of clothing. As an alternative to peroxides, liquids will typically contain only optical brighteners. Liquids do have one advantage over powders – they can be added directly to stains prior to placing the item in the wash. A recent “convenience” version of liquid formulas are highly concentrated detergent pods. Colourful and bearing a resemblance to sweet treats, these products have been found to be <a href="https://poisoncenters.org/track/laundry-detergent-packets">dangerous to young children and people with cognitive impairment</a>. Pods also remove the option to add less detergent if you’re running a smaller load or just want to use less detergent in general. <h2>So, what about enzymes?</h2> Enzymes are naturally evolved proteins included in laundry products to remove specific stains. Chemically, they are catalysts – things that speed up chemical reactions. Enzymes are named for the molecules they work on, followed by the ending “-ase”. For example, lipase breaks down fats (lipids), protease breaks down protein, while amylase and mannanase break down starches and sugars. These enzymes are derived from organisms found in cool climate regions, which helps them function at the low temperature of washing water. Running an excessively hot wash cycle can damage or denature the enzyme structure, stopping them from assisting in your wash. Think of an egg white <a href="https://theconversation.com/how-to-make-the-perfect-pavlova-according-to-chemistry-experts-196485">changing from translucent to white while cooked</a> – that’s protein denaturing. If your detergent contains enzymes, the washing temperature should be neither too hot nor too cold. As a guide, temperatures of 15–20°C are used in <a href="https://environment.ec.europa.eu/document/download/557d8ab5-4e75-41a4-a901-1548be7f685d_en">standard laundry tests</a>. <h2>Is powder or liquid better?</h2> We make consumer choices guided by performance, psychology, cost, scent, environmental considerations and convenience. It’s worth experimenting with different products to find what works best for you and fits your needs, household budget and environmental considerations, such as having <a href="https://theconversation.com/curious-kids-why-can-some-plastics-be-recycled-but-others-cant-229270">recyclable packaging</a>. Personally, I wash at 20°C with half the recommended dose of a pleasant-smelling laundry powder, packaged in recyclable cardboard, and containing a wide range of enzymes and an activated peroxide source. Knowing a little chemistry can go a long way to getting your clothes clean. However, laundry detergent manufacturers don’t always disclose the full list of ingredients on their product packaging. If you want more information on what’s in your product, you have to look at the product website. You can also dig a little deeper by reading documents called <a href="https://theconversation.com/a-new-tiktok-trend-has-people-drinking-toxic-borax-an-expert-explains-the-risks-and-how-to-read-product-labels-210278">safety data sheets</a> (SDS). Every product containing potentially hazardous chemicals must have an SDS.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/239850/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What washing machine settings can I use to make my clothes last longer?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/alessandra-sutti-1513345">Alessandra Sutti</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/amol-patil-1513347">Amol Patil</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/maryam-naebe-1513346">Maryam Naebe</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Orbiting 400 kilometres above Earth’s surface, the astronauts on the International Space Station live a pretty normal social life, if not for one thing: they happily wear their unwashed clothes <a href="https://www.nasa.gov/centers-and-facilities/glenn/nasa-glenn-interns-take-space-washing-machine-designs-for-a-spin/">for days and weeks at a time</a>. They can’t do their laundry <a href="https://www.esa.int/Enabling_Support/Space_Engineering_Technology/Keeping_your_underwear_clean_on_the_Moon">just yet</a> because water is scarce up there. But down here on Earth, washing clothes is a large part of our lives. <a href="https://bigee.net/media/filer_public/2013/03/28/bigee_domestic_washing_machines_worldwide_potential_20130328.pdf">It’s estimated</a> that a volume of water equivalent to 21,000 Olympic swimming pools is used every day for domestic laundry worldwide. Fibres from our clothes make their way into the environment via the air (during use or in the dryer), water (washing) and soil (lint rubbish in landfill). Most of this fibre loss is invisible – we often only notice our favourite clothing is “disappearing” when it’s too late. How can you ensure your favourite outfit will outlast your wish to wear it? Simple question, complex answer. <h2>Washing machines are not gentle</h2> When you clean the filters in your washing machine and dryer, how often do you stop to think that the lint you’re holding <a href="https://theconversation.com/uk-laundry-releases-microfibres-weighing-the-equivalent-of-1-500-buses-each-year-199712">was, in fact, your clothes</a>? Laundering is harsh on our clothes, and <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0250346">research confirms this</a>. Several factors play a role: the type of washing machine, the washing cycle, detergents, temperature, time, and the type of fabric and yarn construction. There are two types of domestic washing machines: top-loader and front-loader. Mechanical agitation (the way the machine moves the clothes around) is one of the things that helps ease dirt off the fabric. Top-loaders have a vertical, bucket-like basket with a paddle, which sloshes clothes around in a large volume of water. Front-loaders have a horizontal bucket which rotates, exposing the clothes to a smaller volume of water – it takes advantage of gravity, not paddles. Top-loading machines <a href="https://link.springer.com/article/10.1007/s12541-010-0047-7">tend to be more aggressive</a> towards fabrics than front-loaders due to the different mechanical action and larger volumes of water. Washing machine panels also present many choices. Shorter, low-temperature programs <a href="https://clevercare.info/more-eco-temperature-tips">are usually sufficient for everyday stains</a>. Choose longer or <a href="https://iprefer30.eu/animations/UK/wash-brochure-uk.pdf">high-temperature programs</a> only for clothing you have concerns about (healthcare uniforms, washable nappies, etc.). Generally, washing machine programs are carefully selected combinations of water volume, agitation intensity and temperature recommended by the manufacturer. They take into consideration the type of fabric and its level of cleanliness. Select the wrong program and you can say goodbye to your favourite top. For example, high temperatures or harsh agitation may cause some fibres to weaken and break, causing holes in the garment. <h2>Some fabrics lose fibres more easily than others</h2> At a microscopic level, the fabric in our clothes is made of yarns – individual fibres twisted together. The nature and length of the fibres, the way they are twisted and the way the yarns form the fabric can determine how many fibres will be lost during a wash. In general, if you want to lose fewer fibres, you should wash less frequently, but some fabrics are affected more than others. Open fabric structures (knits) with loose yarns <a href="https://www.nature.com/articles/s41598-021-98836-6">can lose more fibres</a> than tighter ones. Some sports clothing, like running shirts, are made of continuous filament yarn. These fibres are less likely to come loose in the wash. Cotton fibres are only a few centimetres long. Twisted tightly together into a yarn, they can still escape. Wool fibres are also short, but have an additional feature: scales, which make wool clothes much more delicate. Wool fibres can come loose like cotton ones, but also tangle with each other during the wash due to their scales. This last aspect is what causes wool garments to shrink when <a href="https://journals.sagepub.com/doi/abs/10.1177/004051756403400303">exposed to heat</a> and agitation. <h2>Go easy on the chemicals</h2> The type of detergent and other products you use also makes a difference. Detergents contain a soap component, enzymes to make stains easier to remove at low temperature, and fragrances. Some contain harsher compounds, such as bleaching or whitening agents. Modern detergents are very effective at <a href="https://www.choice.com.au/home-and-living/laundry-and-cleaning/laundry-detergents/review-and-compare/laundry-detergents">removing stains such as food</a>, and you don’t need to use much. An incorrect choice of wash cycles, laundry detergent and bleaching additives could cause disaster. Certain products, like bleach, can <a href="https://site.extension.uga.edu/textiles/textile-basics/understand-your-fibers/">damage some fibres like wool and silk</a>. Meanwhile, research on <a href="https://www.sciencedirect.com/science/article/pii/S0269749120366872?via%3Dihub">fabric softeners and other treatments</a> <a href="https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0233332&type=printable">continues</a> – there’s no one-size-fits-all answer about their potential impact on our clothes. <h2>Just skip laundry day</h2> So, how to ensure your clothes last longer? The main tip is to wash them less often. When it’s time for a wash, carefully read and follow the care labels. In the future, our washing machines will <a href="https://www.teknoscienze.com/tks_article/trends-in-laundry-by-2030/">recognise fabrics and select the wash cycle</a>. For now, that’s our responsibility. And the next time you throw your shirt into the dirty laundry basket, stop. Think of the astronauts orbiting above Earth and ask yourself: if they can go without clean laundry for a few days, maybe I can too? (Although we don’t recommend just burning your dirty undies, either.)<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/224064/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <figure><iframe src="https://www.youtube.com/embed/C1j6KLP492E?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <a href="https://theconversation.com/profiles/alessandra-sutti-1513345">Alessandra Sutti</a>, Associate Professor, Institute for Frontier Materials, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/amol-patil-1513347">Amol Patil</a>, Research Engineer, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/maryam-naebe-1513346">Maryam Naebe</a>, Associate professor, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Uproar over council's bin "shaming" move

As councils around the country make big changes to the way we dispose of waste, one council's move has left an entire street in Melbourne "offended". On Wednesday morning, Essendon mum Kali took out her bins and thought nothing more of her weekly habit. It was when she came back after a coffee run that she spotted a tag that had "oh no" written in big red letters. "We found items that don't belong in your mixed recycling bin," the note read, identifying reusable shopping bags as the culprit. When she looked around all but one household on her street had the same yellow note. "I came back and saw all these tags on the bins, I thought 'That's a bit weird'," she told Yahoo News Australia. "It was the talk of the street," she said, after finding out that fellow residents were in "uproar" over the tags. Kali, a mum-of-two, has lived in her home for over nine years and said this was the first time she saw the tag on her bin. "It's just a bizarre thing to do," she said. "I thought it was funny that I got bin shamed. I'm sure we're all guilty of [recycling incorrectly], it's an easy mistake. "Our whole street was embarrassed about it," she added, saying "other neighbours were more offended". Kali is adamant that she didn't do anything wrong, as she ensures the bags in her bin were made out of paper, but said that "you don’t know who is putting things in your bin." A council spokesperson told Yahoo that the move was made to "inform" residents. "Council’s intention is to provide information to people at their homes through our kerbside bin education program to create more awareness, so everyone in the community can recycle right," the spokesperson said. "We understand that recycling can be confusing and that there may be a misunderstanding in what can and can’t go into a recycling bin." Images: Yahoo News

$15 Kmart hack that'll transform your kitchen

Who doesn't love a cheap hack? For the past few months shoppers have been obsessed with a $15 bathroom item from Kmart, but not for its intended use. Shoppers have used the retailer’s 3 Tier Floor Caddy, which was originally designed to organise toiletries and save floor space, as a coffee station that's not only practical, but looks nice as well. One shopper took it to the next level, by using the $31 Flexi Storage Decorative Shelving from Bunnings and attaching it to two of the Kmart floor caddies to display plants alongside the DIY coffee station. She initially bought the shelves to install on her kitchen wall, but after finding out they weren't sturdy enough, it has been sitting in her home, until she saw the Kmart caddy hack. “I bought these floating shelves from Bunnings but after reading the reviews I found that people had said they are not great! And I was too lazy to take them back,” she wrote. “Then I saw this Kmart hack with the shower caddies and I’m very happy with the result.” Shoppers were impressed with the finished results, praising the "incredible" idea. “This looks excellent. Like you, we have a small kitchen with very limited shelving. You’ve inspired me to do the same,” one wrote. “Awesome, looks amazing,” another added, while a third commented, “That’s so clever, thanks for sharing”. However a few others didn't get the hype, with one saying: “I don’t get coffee stations. Not saying it’s bad. Just think it creates more clutter." Image: Facebook/ Kmart

Ian Thorpe lists luxury home at a discount

Ian Thorpe has returned his luxury Woollahra townhouse to the market for a price of $3.5 million. The Olympic gold medallist previously listed it on the market for $3.7 million in September last year but failed to find a buyer at that price. The townhouse boasts four-bedrooms and three-bathrooms and sits on 250sqm of land. It also has an outdoor swimming pool and a beautiful outdoor tropical garden. Thorpe purchased the home in December 2017 for $2.75 million and has since done extensive renovation work to the property. He remodelled the terrace and added in stylish sliding doors. It also features open plan living areas perfect for families. "It's completely private and secluded," letting agent Courtney Wong told The Sydney Morning Herald in 2023. A description for the property reads: "For those seeking a private escape with all the comforts of a luxury home, this is everything you could have dreamed of and more. "A true gem tucked away at the quiet rear of a boutique block of only six, this residence represents the perfect mix of modernity and the natural world with its contemporary architectural design in a tranquil leafy setting."

"Never been seen before": Fergie reveals new details from 9/11 near miss

Sarah Ferguson, affectionately known as Fergie, has taken to Instagram overnight to share new details of her 9/11 near miss. 24 years on, the Duchess of York, who has previously revealed that she was meant to be in the World Trade Centre's North Tower when the plane struck the building, has shared more details of the day. Fergie recalled how her friend, billionaire businessman Howard Lutnick, gave her an office on the 101st floor of the World Trade Centre at the time, for her charity Chances for Children. The charity's logo had a mascot called Little Red, which was eventually made into a doll for a child named PJ who survived the 1995 Oklahoma City Bombings. On the day of the 9/11 attacks Fergie was due to attend a meeting in the office, but was running late because of an earlier engagement, so she was still on route to the building when the terrorists struck. "I was driving in the car and I was late for work... and Little Red was found in the rubble," she said in the video. Fergie opened a box to reveal her own Little Red doll that survived the attacks. While she has previously talked about the doll, this is the first time she revealed what it looked like. "A fireman picked her up, carried her out, like the fireman that picked up PJ all those years ago in the Oklahoma City Bombing," she continued. "And CNN filmed it and said, 'Look, a child's doll.' And Larry King said, 'That's no child's doll. That's Fergie's Little Red' and she stands for children's rights all over the world and she's a sign of hope for children.

"World's biggest" amber nugget worth over $1 million used as doorstop for decades

An elderly woman in Romania has unknowingly used one of the largest known amber nuggets in the world - worth over €1 million ($1.6 million) - as her doorstop for decades. The woman found the stone in the bed of a stream in Colti, a village in the southeast Romania, and used it as her doorstop for years without realising its value. Members of her family also reported that thieves had once broken into her home, but only stole a few pieces of gold jewelry, missing the seemingly insignificant rock. “In their frantic search for valuables, they overlooked the real treasure that was there before their eyes,” they said. It wasn't until after the woman died in 1991 that a relative who inherited her home suspected the doorstop might be more than meets the eye - and he was right. When he sold the amber to the Romanian state, experts at the Museum of History in Krakow, Poland appraised the rock and found that the amber is likely between around 38 and 70 million years old. “Its discovery represents a great significance both at a scientific level and at a museum level,” Daniel Costache, director of the Provincial Museum of Buzau, told local news outlet El Pais. The expert also claimed that the amber is one of the largest pieces in the world and the largest of its kind weighing a hefty 3.5-kilograms. It has now been classified as a national treasure of Romania, and can be found in the Provincial Museum of Buzau, where it has been since 2022. Romania is one of the countries with significant deposits of amber, with Buzau County being one of the areas where you can find these beautiful stones in abundance. The protected area also contains the old Stramba amber mine, which was very productive during the first half of the 21st century, before it was shut down by the communist regime as it was considered unprofitable.

Snug but unsafe: your heater may be harming your health. What are your safest choices?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/christine-cowie-191638">Christine Cowie</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/bill-dodd-1280161">Bill Dodd</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> We now have a dizzying array of heating technologies to consider, besides the fire that warmed our ancestors. Salespeople will highlight any number of features and minor conveniences. You will be made aware of limited-offer discounts, product warranties, trends in certain Nordic countries, or their low cost (at least in the short-term). What you are less likely to read on the box is, well, the stuff that really matters: the long-term effects on your health and the health of your family, your neighbours and the environment. Yes, a heater should keep you warm affordably. After all, a warm home is vital for your health. But would you run a heater that you knew was increasing the likelihood of your child developing asthma, your partner developing lung cancer, and your neighbour or your grandparent suffering a stroke or heart attack? Many <a href="https://doi.org/10.1016/j.envint.2019.105429">peer-reviewed studies</a> have found domestic heating to be a major source of air pollution and of ill health in Australia. So which heaters are high-risk and which are low-risk? Let’s consider, firstly, the most dangerous heaters. <h2>Extreme-risk heaters</h2> Two rules reduce the risks: <ol> <li> never burn anything (wood, gas or other fuel) in your home without adequate ventilation such as a chimney, exhaust or flue </li> <li> never use an outdoor appliance (heater, cooker, barbecue) inside. </li> </ol> Concerningly, a 2022 <a href="https://asthma.org.au/wp-content/uploads/2022/11/AA2022_Housing-Survey-Report_full_v4.pdf">Asthma Australia survey</a> found 7% of Australians used an unflued gas heater. When gas or other fuel is burnt indoors it releases a range of <a href="https://search.informit.org/doi/abs/10.3316/informit.786585213635569">particles and toxic gases</a>. Most dangerous of all is <a href="https://www.dcceew.gov.au/environment/protection/npi/substances/fact-sheets/carbon-monoxide-0">carbon monoxide</a> (CO). This colourless, odourless gas can build up in unventilated homes, resulting in serious poisoning and death. A recent <a href="https://www.abc.net.au/news/2024-06-29/sydney-family-use-bbq-as-indoor-heater-inhale-carbon-monoxide/104039702">case of carbon monoxide intoxication</a> left three people unconscious in a Sydney home after an outdoor barbecue was used inside as a heater. Outdoor heaters, cookers and barbecues are especially potent sources of carbon monoxide and should never be brought inside. If you have a gas appliance in your home, even if it is ventilated, install a <a href="https://www.energysafe.vic.gov.au/industry-guidance/gas/gas-information-sheets/gis-36-carbon-monoxide-alarms-domestic-use">carbon monoxide alarm</a> for as little as $30. <h2>High-risk heaters</h2> <a href="https://www.sciencedirect.com/science/article/pii/S0048969724012087">The evidence</a> is now very clear: wood heater smoke is a potent source of air pollution and significant cause of ill-health in Australia. The more often you burn, the greater the risk. One <a href="https://doi.org/10.1016/j.envint.2023.108128">large population study</a> found even infrequent wood heater use (30 days or more each year) increases the risk of lung cancer by 68%. Wood heaters spill smoke into the home when refuelling. They also suck smoke from outside back into the home as air is drawn up the chimney. If you can smell your wood heater, it is harming your health and exposing you to a toxic mix of particles and gases. For the wider community, the cumulative health impacts of wood heaters are significant. Less than <a href="https://www.abs.gov.au/ausstats/abs@.nsf/Previousproducts/4602.0.55.001Main%20Features5Mar%202011?opendocument&tabname=Summary&prodno=4602.0.55.001&issue=Mar%202011&num=&view=">10% of Australian households</a> use a wood heater. Yet they are the largest source of particulate air pollution in most Australian cities and towns, including <a href="https://www.environment.nsw.gov.au/-/media/OEH/Corporate-Site/Documents/Air/sydney-air-quality-study-stage-2-program-report-220644.pdf">Sydney</a>, <a href="http://www.doi.org/10.1016/j.scitotenv.2024.171069">Melbourne</a>, <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.52176">Canberra</a>, <a href="http://www.doi.org/10.1016/j.scitotenv.2024.171069">Adelaide</a> and <a href="http://www.doi.org/10.3390/ijerph17093264">Hobart</a>. Even in temperate Sydney, wood heaters emit <a href="https://www.environment.nsw.gov.au/-/media/OEH/Corporate-Site/Documents/Air/sydney-air-quality-study-stage-2-program-report-220644.pdf">more of this pollution</a> than all the cars, trucks, boats and buses combined, and more than coal-fired power stations and industry. <a href="https://safeair.org.au/">Centre for Safe Air</a> researchers <a href="https://doi.org/10.1016/j.scitotenv.2024.171069">estimate</a> wood heaters cause between 558 and 1,555 excess deaths a year in Australia. That’s roughly equivalent to the <a href="https://www.bitre.gov.au/publications/ongoing/road_deaths_australia_monthly_bulletins">annual road toll</a>. Fine particles (2.5 microns or less in diameter – also known as PM2.5) are a major component of wood smoke. PM2.5 increases <a href="https://www.epa.gov/air-research/air-pollution-and-cardiovascular-disease-basics">rates of heart disease and stroke</a>, <a href="https://doi.org/10.3978%2Fj.issn.2072-1439.2016.01.19">lung disease</a>, <a href="https://doi.org/10.1016/j.scitotenv.2018.11.218">dementia and other neurological conditions</a> and <a href="https://asthma.org.au/about-us/advocacy/air-quality">asthma attacks</a>. Risks of <a href="https://doi.org/10.1371/journal.pmed.1003718">adverse pregnancy outcomes</a> and <a href="https://www.eea.europa.eu/publications/air-pollution-and-childrens-health">poorer learning outcomes in children</a> are also increased. <h2>Low-risk heaters</h2> Evidence suggests there is no “safe” level of air pollution, with health effects <a href="https://doi.org/10.1016/j.envint.2019.02.044">seen at very low levels</a>. Even ducted gas heating, where most of the toxins are ventilated, <a href="https://search.informit.org/doi/abs/10.3316/informit.786585213635569">can expose residents to low levels</a> of PM2.5, nitrogen dioxide (NO2), carbon monoxide and formaldehyde. Over time, this can have a range of <a href="https://safeair.org.au/the-health-impacts-of-gas-use-extraction/#gf_1">health impacts</a>, including worsening asthma and respiratory symptoms. Burning gas for heating also adds to greenhouse gas emissions. As Australia transitions to a zero-carbon society, some states and territories are phasing out installation of new wood heaters, such as <a href="https://www.abc.net.au/news/2023-08-24/canberra-to-phase-out-wood-heaters-by-2045/102769162">in the ACT</a>, and gas connections, such as <a href="https://www.planning.vic.gov.au/guides-and-resources/strategies-and-initiatives/victorias-gas-substitution-roadmap">in Victoria</a>. Subsidies to help people replace unhealthy heaters are excellent investments in the environment, public health and health equity. <h2>Healthy heaters</h2> Ultimately, heaters that do not rely on burning fuel inside the home are the safest, and often more affordable, heating option. A <a href="https://www.abc.net.au/news/2023-07-17/cleaning-filters-in-reverse-cycle-air-conditioner-to-save/102594652">well-maintained</a> reverse-cycle air conditioner, sometimes called a heat pump, actually cleans the air inside your home. These air conditioners have the additional benefit of cooling your home in summer. As heatwaves become more severe and frequent, efficient cooling is <a href="https://www.sciencedirect.com/science/article/pii/S0378778823004152">increasingly important for health</a>. As for affordability, an efficient reverse-cycle air conditioner can be up to <a href="https://www.climatechoices.act.gov.au/__data/assets/pdf_file/0005/1862663/Sustainable-Household-Scheme-A-guide-to-reverse-cycle-systems.pdf">seven times as efficient</a> as a gas wall heater in the energy it uses for a given amount of heat. There are many other <a href="https://www.choice.com.au/home-and-living/heating/electric-heaters/articles/which-electric-heater-type-is-best">electric heating technologies</a> – such as fan heaters, oil column heaters, panel heaters, or infrared heaters – that do not release toxins into the home. Heater manufacturers are often reluctant to talk about the health impacts of their products, and regulators are slow to catch up with the science. By thinking about heating in terms of health, you can make your home safer for yourself and the people around you.

Mysterious leg pain that’s quietly killing older Australians

Peripheral Artery Disease (PAD) has long been overshadowed by its more widely recognised counterparts, such as heart attacks and strokes. Often referred to as the “poor cousin” or “Cinderella” of cardiovascular diseases, PAD affects one in five older Australians, yet it remains largely under-diagnosed and misunderstood. However, a wave of optimism is sweeping through the medical community with the launch of <a href="https://www.hri.org.au/our-research/centreforpad" target="_blank" rel="noopener">The Centre for Peripheral Artery Disease</a>, an Australian-first facility dedicated to pioneering research and improving patient outcomes. Spearheaded by the Heart Research Institute, the Centre for Peripheral Artery Disease, marks a significant step forward in addressing the challenges posed by PAD. The centre aims to fill critical gaps in our understanding of the disease, which is responsible for a limb amputation in Australia every two hours. This initiative promises to enhance diagnosis, transform patient care, and raise awareness about PAD. Associate Professor Mary Kavurma, the Centre Lead, is at the forefront of this ground-breaking effort. “We’re supercharging research into PAD because there are still many unknowns about the disease’s biology that could unlock new methods for early detection and better management,” she explains. This research is particularly urgent given the prevalence of PAD among women and First Nations Australians, groups that remain disproportionately affected by this condition. The centre’s mission is to develop a simple blood test for early diagnosis and explore novel therapies that could reduce the need for limb amputations and significantly improve patients’ quality of life. Unlike current treatments that primarily focus on symptom management, this new approach seeks to prevent the disease from progressing. One of the most inspiring aspects of the centre is its commitment to involving patients and their families in the research process. At the inaugural consumer meeting, nearly 20 patients and their carers shared their personal experiences with PAD. Take the story of Simon Josephson, a renowned advertising guru – who famously designed the Solo logo. PAD almost cost him his life after taking more than five years to diagnose. He woke up one morning with a sore leg, thinking he’d overdone it exercising but the 73-year-old – who was otherwise healthy and active – unknowingly had Peripheral Artery Disease, caused by a build-up of plaque in his arteries causing them to narrow and stiffen. It wasn’t until a trip to the hospital emergency department years later that doctors would discover his aorta had expanded to more than twice the usual size and was at risk of rupturing. He immediately underwent open heart surgery and has faced a lengthy recovery. The launch of <a href="https://www.hri.org.au/our-research/centreforpad" target="_blank" rel="noopener">The Centre for Peripheral Artery Disease</a> heralds a new era of hope and progress in the fight against PAD. Through world-leading research, community engagement, and a commitment to patient-centred care, the CPAD is poised to make a profound impact on the lives of many Australians. As Assoc Prof Kavurma aptly put it, “By understanding more about this debilitating condition, we are paving the way for better health outcomes and a brighter future for all those affected by PAD.” Images: CPAD

New York City mocked for only just discovering wheelie bins

New York City has been trolled online after discovering wheelie bins for the first time. In order to tackle the "trash revolution", the mayor of NYC Eric Adams announced that wheelie bins will be introduced city wide, instead of the current system which is just leaving rubbish bags on the street. Despite the introduction of wheelie bins being a great solution for the city's trash and rodent problem, many were shocked to learn that the receptacles don't already exist there. Introducing the roll out, Mayor Adams began his press conference rolling in a bin and proudly demonstrating how to use it before celebrating with colleagues. He said “many people thought it was impossible” that these wheelie bins were going to be part of the city’s “trash revolution”. “We all have one unified dislike, and those are those pesky New York City rats,” Mr Adams said. “They’re getting more and more bold. They no longer run from you. They just hang out and just do what they want. We want to make sure we change that in a real way.” NYC department of sanitation commissioner Jessica Tisch described the official NYC bin as a “beautiful, rat-fighting piece of engineering” to conquer the estimated three million rats that dominate the streets. The wheelie bin announcement, which was intended to impress New Yorkers, has also gone global – with Europeans and Australians baffled by concept of wheelie bins being new. “Oh my word! Are they seriously showing their constituents how to use a trash can?” wrote one person. “Huh, they don’t have wheelie bins? What century do they live in?” said a second. “How the hell is this revolutionary??” agreed another. “So they finally figured out putting your trash in piles on the sidewalk is not a good idea,” mocked someone else.

Plastic Free July is a waste of time if the onus is only on consumers

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/bhavna-middha-1061611">Bhavna Middha</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> and <a href="https://theconversation.com/profiles/ralph-horne-160543">Ralph Horne</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Every year, the <a href="https://www.plasticfreejuly.org/">Plastic Free July</a> campaign asks us to refuse single-use plastic. The idea is that making a small change in our daily lives will collectively make a big difference. And hopefully, better behaviour will stick and become a habit. The intent is good, but consumers shouldn’t have to bear full responsibility for plastic pollution. Individual sacrifices – particularly temporary ones – <a href="https://www.sciencedirect.com/science/article/abs/pii/S0301421509004728">won’t make a significant difference</a>. Governments, manufacturers and retailers need to get serious about tackling this problem. If Plastic Free July put pressure on the supply side of the equation, rather than demand, it could be more successful. Our research spans food packaging including plastics, waste, sustainable consumption and social practices. We know consumer demand is only one part of the picture. Eliminating plastic waste requires broader systemic changes. <h2>The cabbage dilemma</h2> Research shows consumers generally want to do the <a href="https://www.sustainability.vic.gov.au/news/news-articles/the-conversation-on-sustainability-has-changed">right thing by the environment</a> but find it <a href="https://theconversation.com/households-find-low-waste-living-challenging-heres-what-needs-to-change-197022">challenging</a>. Coming out of a supermarket with no packaging is difficult. There are few unpackaged food items and even when there is a choice, the unpackaged item may be more <a href="https://www.smh.com.au/politics/federal/want-your-fruit-and-veg-without-the-plastic-you-ll-have-to-pay-more-20231107-p5eib4.html">expensive</a>. Have you ever been stuck in the supermarket, choosing between the large head of cabbage you know you won’t finish before it goes bad, or the plastic-wrapped half-cabbage you really need? Consumers should not be forced to choose between food waste (another huge problem) or plastic waste. Maybe there’s another way. For example, why not sell cabbages of different sizes? Why do we need to grow such large heads of cabbage anyway? Both plastic consumption and food waste can be addressed by changing how we produce and distribute certain foods. <h2>Governments, manufacturers and retailers must drive change</h2> The onus for reducing plastic consumption and waste should be placed firmly on those who make plastic and profit from selling their products, as well as those who make and sell products wrapped in plastic packaging. Research has shown just <a href="https://www.csiro.au/en/news/All/News/2024/April/Global-study-finds-more-than-half-of-branded-plastic-pollution-linked-to-56-companies?utm_source=pocket_shared">56 companies</a> globally are responsible for more than half of the branded plastic pollution that ends up in the environment. Companies profit from using plastics because it is cheaper to use than changing to alternatives, such as cardboard or compostable materials, or using less packaging. This means companies choosing to avoid using plastics face unfair competition. It’s a tough habit to kick. Industry-led <a href="https://productstewardship.us/what-is-epr/#:%7E:text=Stewardship%20can%20be%20either%20voluntary,product%20stewardship%20required%20by%20law">voluntary schemes</a> are <a href="https://www.insidewaste.com.au/91038-2-product-stewardship-schemes/">limited in terms of both participation and outcomes</a>. Many companies are failing to meet their own <a href="https://www.asyousow.org/report-page/2024-plastic-promises-scorecard">plastic reduction goals</a>. Governments need to step in and force companies to take responsibility for the plastic and packaging they manufacture. In practice, this could involve similar schemes to the container deposit scheme for beverage containers, or returning plastics to stores. Replacing voluntary schemes with mandatory regulations and increased producer responsibility means companies will have to <a href="https://www.insidewaste.com.au/91038-2-product-stewardship-schemes/">invest in long-term changes designed with care</a>. <figure><iframe src="https://www.youtube.com/embed/UnXVU-06ciI?wmode=transparent&start=1" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>What’s Plastic Free July?</figcaption></figure> <h2>Cities are built around plastic</h2> Our previous research has shown plastic performs an essential role in some, <a href="https://rgs-ibg.onlinelibrary.wiley.com/doi/full/10.1111/geoj.12457">constrained circumstances</a>. We found vulnerable householders often rely on plastic to make life manageable, such as using plastics to cover belongings on the balcony, or using plastic cutlery and plates in student apartments with minimal kitchen space. This includes people with accessibility needs, people relying on public transport to shop for groceries, or people who are financially constrained or living in small high-rise <a href="https://theconversation.com/we-cant-keep-putting-apartment-residents-waste-in-the-too-hard-basket-200545">apartments</a>. Unsustainable lifestyles are not so much a choice as a product of poorly planned cities, housing and regulations. It is all very well if you are mobile and well-located, but if you live in a <a href="https://www.abc.net.au/news/2015-07-08/food-deserts-have-serious-consequences-for-residents-experts/6605230">poorly serviced</a> distant suburb and <a href="https://www.unsw.edu.au/newsroom/news/2023/01/are-you-living-in-a-food-desert--these-maps-suggest-it-can-reall">transport groceries or takeaway food</a> or buy things on the go, then plastic is perhaps the only current affordable way to make it work. So campaigns and solutions that do not consider how <a href="https://rgs-ibg.onlinelibrary.wiley.com/doi/full/10.1111/geoj.12457">everyday lives and economy</a> are intertwined with plastics can <a href="https://www.nature.com/articles/s42949-024-00149-w">exclude people and spaces</a> who can’t access the alternatives. For example, there are ways to make <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1745-5871.12464">convenience eating more sustainable</a> in education settings. We have shown how <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1745-5871.12390">canteens and microwaves</a> in shared spaces can enable people to access affordable food with their friends, as in <a href="https://www.charlesabroad.cz/post/german-university-canteens-why-do-they-beat-the-czech-ones">University Mensa in Germany</a>. Our <a href="https://cur.org.au/project/tackling-food-related-single-use-plastics-in-diverse-consumption-contexts/">new research</a> will explore how single-use food-related plastics and packaging form an integral part of our daily lives, including shopping, work, cooking and storage. Sometimes new policies inadvertently disadvantage certain groups and communities, such as the aged, less mobile, people living in apartments, or low socio-economic groups. Before we roll out new policies and regulations, we need to understand the roles these materials play and the kinds of services and value they provide. We aim to develop a framework to inform policies and strategies that enable a just and inclusive transition to reduced plastic use. <h2>What about after July?</h2> Plastic Free July and similar campaigns are based on idea that making a temporary change will lead to more permanent lifestyle changes. But research shows temporary shifts are <a href="http://www.demand.ac.uk/wp-content/uploads/2016/03/DEMAND2016_Full_paper_42-Shove.pdf">very different</a> to <a href="https://pure.manchester.ac.uk/ws/portalfiles/portal/32468813/FULL_TEXT.PDF">structural, permanent shifts</a> in <a href="https://www.taylorfrancis.com/chapters/edit/10.4324/9781315816494-1/introduction-social-practices-intervention-sustainability-beyond-behaviour-change-yolande-strengers-cecily-maller?context=ubx&refId=d608abad-39f9-4bb2-8754-56e9e2000c5e">practices</a>. Supermarkets will still wrap items in plastic and sell single-use plastic, even if we try to buy less during Plastic Free July. Ultimately, the focus should be on designing effective infrastructure and policy solutions for lasting results, considering how demand for plastic is produced in the first place. Some of these changes will require a shift in community expectations and food culture. Rather than pointing the finger at consumers, let’s get to work on redesigning our cities. We need to rethink how everyday practices, manufacturing and distribution systems are structured to eliminate plastic waste.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/233436/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/bhavna-middha-1061611">Bhavna Middha</a>, ARC DECRA and Senior Research Fellow, Centre for Urban Research, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> and <a href="https://theconversation.com/profiles/ralph-horne-160543">Ralph Horne</a>, Associate Deputy Vice Chancellor, Research & Innovation, College of Design & Social Context, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Shopping centre locked down after violent altercation

Two teenage boys have been arrested after a violent altercation broke out in South Australia's largest shopping centre. On Sunday afternoon, three boys allegedly confronted another group of teens at the Westfield Marion centre’s food court armed with “expandable batons”, with reports one of the boys was also armed with a knife. The violent altercation triggered Westfield’s emergency lockdown and evacuation procedures, with alarms blaring throughout the centre and major storefronts locking their doors to keep shoppers safe. Heavily armed specialist police officers stormed the centre in search of the teens, but they were unable to be found. Following hours of investigating, two boys, aged 15 and 16, were found, arrested and charged with assault, affray and aggravated robbery. The two teens will appear in the Adelaide Youth Court on Monday afternoon, and police continue to search for any outstanding suspects. Assistant Commissioner Duval said police knew the identity of a third offender, and encouraged him to turn himself in. “His identity is known, and at some point we will catch up with him,” he told Today. Duval said police believe the boys knew each other and it was "not a random attack". He also confirmed that police had seized two expandable batons from the teens, explaining, "It's a baton that effectively expands, not dissimilar to what police would use." "Certainly the possession of them is very concerning, that formed part of the allegation of what these boys were charged with." Following the incident, a spokesperson for Westfield issued a statement saying the safety of customers, business partners and people is their "highest priority". Image credits: Nine News

Miss World Australia attacked outside shopping centre

Miss World Australia has taken aim at the lack of police response after she called Triple Zero for urgent assistance when she was attacked. Jasmine Stringer was running a workshop with a group of aspiring young pageant contestants at a Gold Coast shopping centre on Friday night, when a woman lunged towards the group in a random attack. "This person was hurling abuse at the young girls and then charged at me from across the road and punched me straight in the face," Jasmine told <a href="https://9now.nine.com.au/today/miss-world-australia-and-children-attacked-during-gold-coast-shopping-centre-event/cf15799c-99e7-45ee-b143-519bcff1114f" target="_blank" rel="noopener">Today</a>. "I fended her off and then she turned her sights to a 14-year-old girl." While doing her best to protect herself and the young girls, Jasmine called Triple Zero for assistance. As the young girls fled from the scene, Jasmine waited for police - or members of the public - to help, and was met with no response. "I guess the most concerning part of this whole story for me is that I called Triple Zero, we are in the Southport CBD of the Gold Coast, less than three kilometres from the police station and in a 15-minute time frame when women and children are being assaulted, there was no one turning up to help," the 27-year-old said. "I stayed there for 20 minutes on the call with the dispatcher and I was starting to get stressed, this woman was still physically attacking these children as they're trying to get into cars and taxis and it was escalating and I asked 'is someone coming?' and they were quite dismissive to me." As part of her Miss World Australia advocacy work, Jasmine has devoted a lot of time and effort into preventing violence against women, and says this attack is the second time within a month that she's called for help from police after witnessing a violent incident and there's been nobody there to help. 'I'm going to go to the police station today just make sure that the report is made and hopefully have the person who attacked us charged," she said. "But at this point in time, I've received no follow up from the police and it's been a really distressing situation." Image credits: Today

"Can't WAIT to try this": Tradie's simple bin night hack

Taking the wheelie bins out and having to drag them back in is a chore that many dread, but one Aussie tradie has made life so much easier with his simple hack. Kyle Hume took to TikTok to share his simple yet effective trick to bring in two bins back from the curb at the same time, without having to wrangle two bins with both hands or make multiple trips. "I've been wheeling two bins my whole life until I noticed this," he shared. Hume's trick is to line up two bins in front of each other, resting the lid of the bin at the front on top of the bin at the back, and then closing the lid so it creates a makeshift hook that allows you to tip both bins back and wheel them in unison. <div class="embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; outline: none !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; outline: none !important; width: 573px; max-width: 100%;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7360205539604696336&display_name=tiktok&url=https%3A%2F%2Fwww.tiktok.com%2F%40kylehume7%2Fvideo%2F7360205539604696336%3Flang%3Den&image=https%3A%2F%2Fp16-sign-sg.tiktokcdn.com%2Fobj%2Ftos-alisg-p-0037%2FoYPnEqGncBAAtH22Eli4AIzBQC4wEANEIsf1ki%3Fx-expires%3D1715479200%26x-signature%3Di%252BOzi1g942kcQ1F0%252FqQuNd7eiho%253D&key=59e3ae3acaa649a5a98672932445e203&type=text%2Fhtml&schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> Many Aussies were "flabbergasted" by the trick, taking to the comments to express their shock at the simple method. "I've learned more on TikTok about adulting than I ever did in school," one joked. "I have four bins - this is going to save my life," another added. "What? Are you kidding me?" a third exclaimed. However, not everyone was impressed with his method, with some saying that it wouldn't work and there is a risk of damaging the bins. "Guessing that green bin slipped over and split using this hack, lol," one wrote. "This seems awkward and clunky," another added. "Don't you have two arms?" a third wrote. Images: TikTok

Vinegar and baking soda: a cleaning hack or just a bunch of fizz?

<a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Vinegar and baking soda are staples in the kitchen. Many of us have combined them in childhood scientific experiments: think fizzy volcanoes and geysers. But people also frequently mix vinegar and baking soda to produce a reportedly effective household cleaner. Unfortunately, the chemistry behind the bubbly reaction doesn’t support the cleaning hype. The fizzy action is essentially <a href="https://theconversation.com/six-surprising-things-about-placebos-everyone-should-know-220829">a visual “placebo</a>”, formed by the combination of an acid and a base. So, how does it work, and is it worth using these chemicals for cleaning? To understand all this, it helps to know a little more about chemistry. <h2>What’s an acid?</h2> Foods with a sour taste typically contain acids. These include citric acid in lemon juice, malic acid in apples, lactic acid in yoghurt and <a href="https://theconversation.com/kitchen-science-everything-you-eat-is-made-of-chemicals-56583">phosphoric acids in soft drinks</a>. Most vinegars contain around 4–10% acetic acid, the rest is water and small amounts of flavour chemicals. There are other naturally occurring acids, such as formic acid in ant bites and hydrochloric acid in our stomachs. Industrially, sulfuric acid is used in mineral processing, nitric acid for <a href="https://theconversation.com/what-is-ammonium-nitrate-the-chemical-that-exploded-in-beirut-143979">fertiliser manufacturing</a> and the highly potent hydrofluoric acid is used to etch glass. All of these acids share similar properties. They can all release hydrogen ions (positively charged atoms) into water. Depending on their potency, acids can also dissolve minerals and metals through various chemical reactions. This is why vinegar is an excellent cleaner for showers or kettles – it can react with and dissolve mineral deposits like limescale. Other common acidic cleaning ingredients are oxalic acid, used for revitalising timber decks, hydrochloric acid in concrete and masonry cleaners, and sulfamic acid in potent toilet cleaners. <h2>What’s a base?</h2> In chemistry, bases – the opposite of acids in many ways – can bind, rather than release hydrogen ions. This can help lift and dissolve insoluble grime into water. Bases can also break apart fat molecules. Baking soda (also known as sodium hydrogen carbonate, sodium bicarbonate, or bicarb) is a relatively weak base. Stronger common bases include sodium carbonate (washing soda), sodium hydroxide (lye) and ammonia. <a href="https://theconversation.com/spill-at-a-nuclear-facility-shows-potential-burn-risks-from-a-household-chemical-112763">Sodium hydroxide</a> is a potent drain cleaner – its strong base properties can dissolve fats and hair. This allows blockages to be broken down and easily flushed away. <h2>Mixing a base and an acid</h2> Mixing vinegar and baking soda causes an immediate chemical reaction. This reaction forms water, sodium acetate (a salt) and carbon dioxide – the fizzy part. The amount of carbon dioxide gas that is produced from baking soda is remarkable – one tablespoon (around 18 grams) can release over <a href="https://www.chemedx.org/JCESoft/jcesoftSubscriber/CCA/CCA8/MAIN/8/06/2/4/movie.html">five litres of gas</a>! But only if you add enough acid. Reactions in chemistry often use equal quantities of chemical reagents. A perfect balance of acetic acid and baking soda would give you just water, carbon dioxide and sodium acetate. But the majority of vinegar and bicarb cleaner recipes use a large excess of one or the other components. An example from TikTok for a DIY oven cleaner calls for one and a half cups of baking soda and one quarter cup of vinegar. Crunching the numbers behind the chemical reaction shows that after the fizz subsides, over 99% of the added baking soda remains. So the active cleaning agent here is actually the baking soda (and the “elbow grease” of scrubbing). Ovens can be cleaned much more rigorously with stronger, sodium hydroxide based cleaners (although these are also more caustic). Many modern ovens also have a self-cleaning feature, so read your product manual before reaching for a chemical cleaner of any sort. <h2>What about the sodium acetate?</h2> Devotees of vinegar and baking soda mixtures might be wondering if the product of the fizzy reaction, sodium acetate, is the undercover cleaning agent. Unfortunately, sodium acetate is an even weaker base than baking soda, so it doesn’t do much to clean the surface you’re trying to scrub. Sodium acetate is used in <a href="https://www.youtube.com/watch?v=vABpel-11Nc">crystallisation-based heating packs</a> and as a concrete sealant, but not typically as a cleaner. Fun fact: sodium acetate can be combined with acetic acid to make a crystalline <a href="https://theconversation.com/busting-the-myth-that-all-food-additives-are-bad-a-quick-guide-for-label-readers-82883">food additive</a> called sodium diacetate. These crystals give the vinegar flavour to <a href="https://www.youtube.com/watch?v=N0hEutu_goY">salt and vinegar chips</a> without making them soggy. <h2>Sorry to burst your bubbles</h2> There are a few rare cases where mixing vinegar and baking soda may be useful for cleaning. This is where the bubbling has a mechanical effect, such as in a blocked drain. But in most cases you’ll want to use either vinegar or baking soda by itself, depending on what you’re trying to clean. It will be less <a href="https://theconversation.com/visually-striking-science-experiments-at-school-can-be-fun-inspiring-and-safe-banning-is-not-the-answer-195362">visually exciting</a>, but it should get the job done. Lastly, remember that mixing cleaning chemicals at home can be risky. Always carefully read the product label and directions before engaging in DIY concoctions. And, to be extra sure, you can find out more safety information by reading the product’s <a href="https://theconversation.com/a-new-tiktok-trend-has-people-drinking-toxic-borax-an-expert-explains-the-risks-and-how-to-read-product-labels-210278">safety data sheet</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/225177/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

New details on man killed by snake at childcare centre

A childcare centre in Queensland, where father-of-three suffered a <a href="https://www.oversixty.com.au/health/caring/dad-dies-after-being-bitten-by-deadly-snake-in-child-care-centre" target="_blank" rel="noopener">fatal snake bite</a>, is under investigation by workplace safety officials. Jerromy Brookes, 47, was bitten multiple times on his arm while attempting to remove a snake from the premises on Tuesday afternoon. He was not a qualified snake catcher, and tragically passed away in Townsville Hospital after going into cardiac arrest at his home in Deeragun. “Workplace Health and Safety Queensland (WHSQ) is investigating an incident that occurred at a business in Townsville,” a spokesperson told 7News. “As this is a current investigation, WHSQ is not able to provide further information at this time.” WHSQ has the power to prosecute allegations of workplace safety breaches. Brooke is survived by his wife and three children. His wife was the person who called emergency services and provided first aid when Brookes began showing symptoms at home. A family friend has paid tribute to the fallen father saying: “Jerromy was helping remove a snake from another childcare centre in Townsville when the incident occurred." “He was doing his very best to keep the children safe.” It was believed that Brookes was trying to remove an eastern brown snake, one of the deadliest in the world, however the species has not been officially confirmed. Police are reportedly not investigating the incident as a criminal matter, but are working to provide a report for the coroner. Images: Facebook

Dad dies after being bitten by deadly snake in child care centre

A beloved father has passed away after reportedly trying to remove an eastern brown snake from a child care centre in North Queensland. Jeremy Brookes attended the child care centre on Tuesday afternoon after one of his relatives reportedly called him over to remove the snake, according to The Courier Mail. Brookes was not a qualified snake handler and was bitten multiple times on his hand and arm. According to Queensland Ambulance Service acting district director Paula Marten, Brookes then managed to drive to his Deeragun home but he soon went into cardiac arrest. HIs wife performed CPR until paramedics arrived and he was rushed to hospital, but unfortunately could not be saved. “(He) was found to be in cardiac arrest by our crews,” Marten said. “The call was made by the patient’s wife, who then commenced CPR as the patient went into cardiac arrest. “The information provided to us was that the gentleman had been bitten in a different location and attended back to his residence, where his wife has immobilised his arm and wrapped it, when the onset of the symptoms occurred.” She added that snake bites were common in North Queensland and they were rarely fatal, but advised that if "you’re not aware of snakes, treat them as if they are venomous." “It’s really important that you stay calm and keep the person calm. “Apply basic first aid, which would be immobilisation and using compression bandages, and contact triple-0. “If you are unsure about what first aid measures to take, call triple-0, and they will walk you through what you need to do for the patient.” Eastern Brown Snakes are one of the most deadly snakes in the world, with the second most toxic venom. They can be found across the east of Australia including the Northern Territory, Queensland, South Australia, Victoria, NSW and the ACT. Brookes is believed to be the first person to have died from a snake bite in Australia this year. Last year, two people died from suspected eastern brown snake bites in Australia.

Heartless theft from "Garden of Little Angels"

In a despicable act of heartlessness, dozens of bronze plaques dedicated to children have been stolen from a memorial park in Melbourne's southwest. The theft not only deprives grieving families of precious mementos but also desecrates a sacred space meant to honour the memory of lost loved ones. Victoria police were alerted to the crime when it was discovered that 75 plaques had been taken from Altona Memorial Park on Doherty’s Road. These plaques, erected in the "Garden of Little Angels", were loving tributes from families who had lost children, serving as symbols of remembrance and healing for those who visit the park. The theft, which occurred sometime between March 12 and 13, has left the community shocked and appalled. It is a violation not only of property but of the sanctity of a space meant for solace and reflection. The perpetrators have callously disregarded the pain of grieving families and the significance of the memorial to the community. In response to this reprehensible act, detectives have issued a warning to scrap metal dealers in the area to remain vigilant against any attempts to sell the stolen plaques. These plaques, though they may hold some monetary value as scrap metal, are priceless to the families who placed them in the memorial park, with their sentimental worth far outweighing any material gain. The police are actively investigating the theft and are urging anyone with information to come forward. The return of the stolen plaques to their rightful place is paramount in restoring a sense of peace and closure to the families affected by this crime. Images: Altona Memorial Park

Better Homes and Gardens star's dream rural property up for grabs

Better Homes and Gardens star Charlie Albone and his wife interior designer Juliet Love, have listed their dream Ourimbah home. The 2.07ha property located on the Central Coast has been listed by McGrath Gosford agents Peter Morris and Nate Waters with a $3m to $3.2m price guidance. The four-bedroom, three-bathroom home sits deep behind a gated entry, which ensures privacy and is surrounded by plenty of greenery with its garden alcoves, a stunning wisteria-covered arbour, fruit trees, and a few garden beds for vegetables. There is also a feature dry-stone wall fire pit built by Scottish stonemason Callum Grey, that's perfect for winter and colder nights. The English cottage-style home comes with a separate self-contained unit that includes a bedroom and kitchenette. The home is every animal lovers' dream with five paddocks that come with animal shelters, plumbed water troughs and a three-stall stable. For those hot summer days, whoever the new owners are can dip into the saltwater pool located on the property. The property is equipped with 100,000-litre tanks and has town water. Albone and his family bought the property in 2012 for $840,000 which means that if it was sold at the price guide then it's almost four times the original price they bought it at. The top acreage sale at Ourimbah currently sits at $3,725,000 for a 13.93ha Dog Trap Rd six-bedroom house, which sold in 2021. Images: news.com.au
