Simple method destroys dangerous ‘forever chemicals,’ making water safe

water

Key takeaways: World’s water tainted. Synthetic PFAS, which have been linked to cancer and other diseases, have contaminated nearly every drop of water on the planet. Unbreakable bond. These chemicals contain a carbon-fluorine bond that is almost impossible to break, making it extremely difficult to eradicate them from water supplies. Off with their heads! Researchers devised a “guillotine” solution that uses moderate heat ...

How to detect nanoplastics present in air

Large pieces of plastic can break down into nanosized particles that often find their way into the soil and water. Perhaps less well known is that they can also float in the air. It’s unclear how nanoplastics impact human health, but animal studies suggest they’re potentially harmful. As a step toward better understanding the prevalence of airborne nanoplastics, researchers have ...
