The environmental consequences of PFAS, especially from firefighting activities, have been recognized since the mid-1990s and came to prominence after the Buncefield explosion on 11 December 2005. The Environment Agency has undertaken a series of projects to understand the scale and nature of PFAS in the environment.
Per- and polyfluoroalkyl substances – also known as PFAs – are widely used, long lasting chemicals found in many consumer, commercial, and industrial products. [2] Breaking down very slowly in the environment, PFAs have been found in water, air, fish, soil, the blood of humans and animals, and food products around the world.
Perfluorooctanesulfonic acid is usually used as the sodium or potassium salts. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. PFOS, together with PFOA, has also been used to make aqueous film forming foam (AFFF), a component of fire-fighting foams, and alcohol-type concentrate foams.
Aqueous film-forming foam, or AFFF, is a product used to fight fires. The PFAS chemicals in AFFF have entered the environment, contaminating it and causing harm to South Carolina’s natural ...
The PFAS pesticides are also used in flea treatments for pets and insect-killing sprays in homes, according to the research conducted by scientists at EWG, the Center for Biological Diversity in ...
New Mexico Environment Department Secretary James Kenney supports both bills, and told Source that per-and-polyfluoroalkyl—aka PFAS—contamination is the “thing that keeps him up at night.”
PFAS, synthetic pollutants with known potential harm to wildlife, humans, and the environment, are commonly found in FCMs, including reusable plastics. As a shift away from plastic, paper and other plant-based materials are increasingly utilized in commercial settings, including the production of drinking straws, purportedly to mitigate plastic ...
All of these methods promote the formation of hydroxyl radicals or other oxidizing agents that can oxidize PFAS and break its C−C bonds. [3] [4] However, the remediation of PFAS depends on the environmental medium where the these compounds reside. For example, the treatment of contaminated soil, biosolids and water is not the same, and risk ...
