Microplastics are adsorbing zinc oxide from sunscreens and microbeads from cleansers
A new study by a research team from Diamond Light Source looks at how microplastics wastes may interact with zinc oxide (ZnO) nanomaterials in freshwater and seawater scenarios. It also evaluated, a ZnO-based sunscreen and an exfoliating cleanser wit.....»»
Check your tires: You might be adding microplastics to the environment
Cost-saving measures are key in today's economic climate. But they can also have a positive impact on minimizing your environmental footprint. A prime example is maintaining your cars' optimal tire pressure......»»
New model for predicting adsorption of PFAS by microplastics
Rivers, lakes and oceans worldwide are home to trillions of pieces of plastic pollution that are smaller than five millimeters in length, known as microplastics, and their size allows them to easily enter humans and animals. Some can adsorb and trans.....»»
Studying the effects of microplastics on the infectivity of bacteriophages in an aqueous environment
Polymer-based materials are almost everywhere, reaching even the deepest regions of the oceans, and their global production outpaces recycling, leading to the generation of tremendous amounts of water pollution with microplastics. These tiny polymer.....»»
Yet another problem with recycling: It spews microplastics
One recycling facility emits as much as 3 million pounds of microplastics a year. Enlarge (credit: Getty Images) The plastics industry has long hyped recycling, even though it is well awarethat it’s been a failure. Wor.....»»
Yet Another Problem With Recycling: It Spews Microplastics
Recycling was already a mess. Now a study finds that one facility may emit 3 million pounds of microplastics a year......»»
Biofortification of microgreens with zinc could mitigate global "hidden hunger"
When the seeds of plants such as pea and sunflower are biofortified with zinc, the seedlings they quickly produce—harvested as microgreens—could both help to mitigate global malnutrition and boost the odds of people surviving a catastrophe......»»
Crystal phase-dependent activity of mnGaOx observed in direct syngas to light olefins
Two notable metal oxide structures, spinel-type oxide and solid solution-type oxide, are widely used in Oxide-Zeolite (OXZEO) bifunctional catalysts for CO/CO2 hydrogenation reactions......»»
Researchers develop "green" way to extract hair compounds that could be used for bandages, sunscreens
Hair styling can be a potent form of self-expression, whether it features dramatic updos, intricate braids or crazy colors. Beyond being a reflection of our personality, these strands contain compounds that could one day appear in bandages, sunscreen.....»»
Iron oxide nanoparticles for medical applications: Study clarifies effect of microstructure on magnetic properties
Iron oxide nanoparticles are often used in medical technology as contrast agents for magnetic resonance imaging or as transport agents for drugs in the bloodstream, for example in tumor therapy. For these applications, the nanoparticles have to be bi.....»»
Microplastics have infected critical Arctic ice algae
A critical component of the food web in the Arctic is at risk. According to a new study published in the journal Environmental Science and … The post Microplastics have infected critical Arctic ice algae appeared first on BGR. A crit.....»»
A Critical Arctic Organism Is Now Infested With Microplastics
The algae Melosira arctica is the foundation of the food chain, and its contamination could have major consequences for ecosystems and the climate......»»
Arctic ice algae heavily contaminated with microplastics, reports new research
The alga Melosira arctica, which grows under Arctic sea ice, contains ten times as many microplastic particles as the surrounding seawater. This concentration at the base of the food web poses a threat to creatures that feed on the algae at the sea s.....»»
Nitrous oxide: Why the environment isn"t amused about laughing gas
A young man breathes deeply from a gas-filled bag. He begins to feel a pleasurable sensation "particularly in the chest and extremities" before dancing around and then collapsing in a heap. A few minutes later he comes to and is consumed by a fit of.....»»
Novel durable copper-aluminum-zinc shape memory alloys for energy-efficient refrigeration
The elastocaloric effect is a phenomenon where a material displays a temperature change when it is exposed to a mechanical stress. The change in temperature occurs due to an entropy difference resulting from a martensitic transformation accompanied b.....»»
Q&A: Two ways researchers are studying marine microplastics
Tiny pieces of plastic in the ocean might seem innocuous on their own, but their growing presence is a frustrating issue facing marine ecosystems. The particles' small size makes them difficult to clean up, and it also allows them to easily burrow in.....»»
Why using more fertilizer and feed does not necessarily raise dairy farm profits but increases climate harm
New Zealand is in an unusual position in the developed world when it comes to greenhouse gas emissions. About half of all emissions come from agriculture, and almost a quarter can be attributed to biological emissions (nitrous oxide and methane) from.....»»
77% more microplastics found in River Thames during lockdown may be due to discarded face masks and PPE, research shows
At a first glance the COVID-19 pandemic seemed to have a positive impact on the environment, with significant decreases in greenhouse gas emissions, and transport-related noise, air and light pollution......»»
To fight cancer, EPA wants sterilizer companies to emit less
The Environmental Protection Agency on Tuesday proposed limiting the use of the chemical ethylene oxide after finding a higher than expected cancer risk at facilities that use it to sterilize billions of medical devices each year......»»
Scientists use peroxide to peer into metal oxide reactions
Researchers at Binghamton University led research partnering with the Center for Functional Nanomaterials (CFN)—a U.S. Department of Energy (DOE) Office of Science User Facility at Brookhaven National Laboratory—to get a better look at how peroxi.....»»
Biden is set to propose toughest-ever rules on car pollution to spur EVs
