Everyone at the business was accounted for and there were no reports of any injuries. Both emergency services were however at the scene for more than 10 hours. In an update given today (Monday), a spokesperson for Greater Manchester Police (GMP) said that it was believed 'a container had hydrogen peroxide in it, moisture got into it, and caused it to smoke.' Join the Manchester Evening News WhatsApp group HERE The chemical is often used as an oxidizer, bleaching agent, and antiseptic, amongst other uses. The container was removed from the building into the yard and will be removed fully today, the GMP spokesperson said, adding there was no gas emitting from the site and there was 'no further risk.' A GMFRS spokesperson said 'made it safe alongside partners and there was no risk to public.. They left the scene around 8:20pm and handed the site back to the owners, they added.

Scientists may have solved a chemistry mystery about Jupiter's ocean moon Europa
When you buy through links on our articles, Future and its syndication partners may earn a commission. A long-standing mystery about the presence of hydrogen peroxide (H2O2) on Jupiter's icy ocean moon Europa may be closer to being solved. Hydrogen peroxide forms as a byproduct when energetic particles break apart water molecules, leading to the recombination of OH radicals — highly reactive molecules with unpaired electrons. H2O2 was first observed on Europa by the Galileo Near Infrared Mapping Spectrometer, a scientific instrument aboard NASA's Galileo Jupiter orbiter that was designed to study the composition and surface features of the gas giant's moons and atmosphere using infrared light. Later, the James Webb Space Telescope (JWST) noticed elevated levels of hydrogen peroxide in unexpected areas on the Jovian satellite. Lab studies predicted that higher concentrations of hydrogen peroxide would be found in Europa's colder polar regions — but JWST observations showed the opposite, detecting higher levels in the moon's warmer equatorial regions. These areas, known as chaos terrains, are marked by broken blocks of surface ice that appear to have shifted, drifted and refrozen. "Europa's peroxide distribution does not follow the temperature dependence predicted for pure water ice," wrote the team in their paper. Lab studies consistently show that colder ice has more H2O2, while warmer ice has less. In a new study, scientists report that they have noticed higher levels of carbon dioxide (CO2) in the chaos terrains alongside elevated levels of H2O2. This is probably the result of CO2 escaping Europa's subsurface ocean through cracks in the ice, the researchers say. The team therefore wondered if the presence of CO2 might be changing the ice's chemistry. "Could the presence of CO2 drive the enhanced peroxide production in Europa's chaos regions, signaling a surface composition more conducive to the formation of this radiolytic oxidant?" they wrote in their paper. "Supporting this hypothesis are preliminary experiments on irradiated H2O-CO2 ice mixtures that show increased H2O2 yields compared to pure water ice." To find a definitive answer, they "simulated the surface environment of Europa inside a vacuum chamber by depositing water ice mixed with CO2," Bereket Mamo, a graduate student at The University of Texas at San Antonio and a contractor with the Southwest Research Institute, said in a statement. "We then irradiated this ice mixture with energetic electrons to see how the peroxide production changed." The experiment confirmed what the team had suspected: Even small amounts of CO2 in water ice can greatly boost hydrogen peroxide production at temperatures similar to those on Europa's surface, helping to explain the unexpected JWST observations. This occurs because CO2 molecules behave as "molecular scavengers," grabbing hold of any stray electrons produced when radiation hits the water ice. By capturing these electrons, the CO2 helps protect hydrogen peroxide from being broken apart by further impacts or reactions.

"In fact, an entire NASA mission, the Europa Clipper, is en route to the Jovian system right now to explore the icy moon and help us understand Europa's habitability. "Our experiments provide clues to better understand JWST Europa observations and serve as a prelude to upcoming close-range investigations by Europa Clipper and ESA's [the European Space Agency] JUICE spacecraft," Cartwright added.

The B&Q buy that banishes black mould in a bathroom without bleach & you don't need to spend ages scrubbing either
THE cold and damp winter months may be behind us for now, but many households will still be suffering from mould. UK homes often end up with condensation and mould during winter and early spring, with the bathroom being the most common room affected. 3 3 Thankfully, cleaning pros have revealed a product you can grab on the high street to tackle even the toughest of stains. Even if you clean your bathroom daily, mould is a common problem because of the humidity levels caused by showers and baths. Mould can grow on sealant around the windows, bath, and sink, making your bathroom look dirty no matter what you do. It can look unsightly in the home - but that's not the only problem mould causes. The NHS states if you have damp and mould in your home you're more likely to have respiratory problems, respiratory infections, allergies or asthma. Damp and mould can also affect the immune system. Taking to Instagram, the pros from @thecleangroup have revealed how a supermarket buy can make all the difference - and there's no scrubbing involved. "Totally natural & totally powerful. You don't need to use toxic chemicals to banish black mould," they captioned the viral post. So, what's the secret? The combination of hydrogen peroxide and some simple kitchen roll is all you need. New Build Home Full Of Mould The best part is you don't need to break the bank to get your hands on it either, since hydrogen peroxide can be bought from B&Q for just £8.99. Of course, you won't need to use a full bottle since you'll only need to cover the affected areas, meaning the trick will work out to as little as 30p. First decant 6% Hydrogen Peroxide into a spray bottle and spritz any areas with black mould. Then line the same areas with kitchen roll and spray again before waiting 30 minutes to remove everything - you should make sure to wear gloves when using hydrogen peroxide as well. Finish up by rinsing the same area thoroughly and you'll be left with a bathroom that looks as good as new. "That's it! No scrubbing, no toxic chemicals and no bleach," the pros said. After sharing the trick on Instagram other cleaning fans couldn't believe how well it worked. One said: "This is brilliant, thank you!" And a second commented: "I'm giving my daughters house a full reset while she's off for the weekend and I know she had this problem so thanks for sharing this." "I've never tried this, I always use white vinegar but great results," another wrote. 3 An expert's guide to removing mould and repainting walls Not only does mould look ugly, but if it's not treated properly it can impact your health. Ronseal shared its guide to removing, fixing and preventing mould infestations. You should only remove mould if it's caused by condensation and covers an area smaller than one metre squared. If the mould is caused by sewage or contaminated water, call in a professional. Before you start, wear goggles, long rubber gloves and a mask that covers your nose and mouth to protect you from the mould spores. Open the windows for added ventilation but keep the doors shut to avoid spores spreading. How to remove mould from walls: Fill a bucket with water and mild detergent like washing up liquid. Or use a dedicated mould remover to make quick work of it. Dip a cloth in water and wipe the mould off the wall. Don't brush it as this can release mould spores. Once you've removed the mould, use a dry rag to remove the rest of the moisture. Throw away the cloth and vacuum the room to make sure you've removed all of the spores. How to paint over mould: Never ever paint over mould without killing it first. It won't tackle the source of the problem and will make it look worse. Once you've treated the affected area, use a specialist anti-mould paint to finish the job. Damp stains can be painted over with a suitable paint like Ronseal's 6 Year Anti Mould Paint, so long as the damp has dried and the source has been treated. Some damp sealants can be applied directly onto a wet surface, so check the instructions before you begin.

Using Hydrogen Peroxide to Remove Earwax
Ear drops with hydrogen peroxide may be a safe, cost-effective, and easy-to-use treatment to help remove earwax buildup at home. Hydrogen peroxide is a common ingredient in liquid ear drops, known as cerumenolytics. These are typically the first methods used to help treat an ear impaction, which may be caused by excess earwax. They may also be used to soften earwax before other treatments. Ear wax, or cerumen, is a natural substance that helps protect your ear canal from water, infection, and irritants. However, nearly 6% of people in the United States have cerumen impaction, which may cause: Seeking prompt medical attention If you experience any of the following symptoms, see a medical professional promptly because these are not symptoms of a wax impaction but could be a sign of a more serious cause: acute pain leaking of liquids bleeding in your ear Treating an ear wax impaction Over-the-counter (OTC) cerumenolytic solutions typically contain 3% hydrogen peroxide. They release oxygen to soften, break up, or dissolve your earwax. Carbamide peroxide is a commonly prescribed ear drop. Ear drop treatment Here's a general approach to using hydrogen peroxide ear drops: Lie on your side with the affected ear facing the ceiling. Administer the instructed number of drops into your ear canal. It's common to hear a crinkling, fizzling, or bubbling sound when the liquid solution enters your ear canal. Keep still for 5 minutes or as long as the ear drops' guidelines state. Sit up and lean over a sink to allow any liquid to leak out or use a tissue to blot the outer ear. Repeat this process for your other ear if necessary. The treatment amount, frequency, and duration may vary depending on the brand and solution type. For example, you may need to administer your drops more than once per day over several days. Always read the ear drop application guidelines. Risks of using hydrogen peroxide ear drops Speak with a doctor before using hydrogen peroxide ear drops, especially if you've had, or currently have, a ruptured ear drum, infection, or tympanostomy tubes. In some cases, cerumenolytic solutions may cause: ear canal infection ear canal irritation, itchiness, or pain contact dermatitis Alternative treatments for earwax impaction If hydrogen peroxide ear drops aren't doing the trick for you, speak with a doctor to discuss safe alternative earwax removal methods, such as: irrigation microsuction manual removal, such as with a pic, curette, or alligator forceps oil- or water-based ear drops home remedies It's important never to put objects cotton swabs and ear candles in your ears. Despite popular belief, these may push the earwax further into your ear and cause serious complications. Frequently asked questions about hydrogen peroxide for earwax Does hydrogen peroxide really dissolve ear wax? Hydrogen peroxide eardrops can help soften earwax.
