Water filters with nanoscale channels selectively remove stubborn “eternal chemicals”
Credit: Monash University Traditional water filters struggle to remove smaller PFAS molecules, but the new Monash designed filter changes it. Researchers at Monash University have developed water filter membranes that effectively remove small PFA molecules, overcoming the important challenges faced by traditional water filters. The researchers designed beta-cyclodextrin (βCD)-modified graphene oxide (GO-βCD) membranes using nanoscale channels that selectively retain PFA…

Greenland Inuit faces health risks from “eternal chemicals” in their diet
Scientists said East Greenland is a hot spot for pollution as polar bears and ringed seals can be eaten there. Scientists warned Thursday that the long-term health of East Greenland’s Inuit Hunters is under threat due to the so-called “eternal chemicals” in the atmosphere and the diet of polar bears and sealed meat. Christian Sonne, a graduate of Aafs University…

Canada proposes phase-out of “eternal chemicals” in consumer products
Credit: Pixabay/CC0 Public Domain On Wednesday, Canada proposed “eternal chemicals” in stages in many consumer products after it was found to be toxic and harmful at the current high levels seen in people and the environment. It will occur over several years after consultations, from 2027. At the Montreal fire department, Environment Minister Stephen Gilby said firefighters containing these chemicals…

New carbon-based materials can remove dangerous “eternal chemicals” from the water
Membrane distillation methods can effectively reduce PFAS concentrations by affecting water purification. Credit: Science Tokyo A diverse group of synthetic chemicals, Perfluoroalkyl and polyfluoroalkyl substances (PFAs) are commonly used in numerous products, including semiconductors, fire-steamed foam, heat-resistant, and non-adhesive cooking utensils. PFAs have a prominent resistance to heat, oil, grease, and water due to strong chemical bonds between atoms. However,…
