It is commonly referred to as the main harmful PFAS chemical and PFOA is responsible for many of the negative health effects commonly associated with PFAS. Per- and polyfluoroalkyl substances are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain. Different organizations use ...
Dr. Carmen Marsit: PFAS are a class of about 15,000 human-made chemicals that contain fluorine groups, which give them special properties. They are in nonstick surfaces; they’re used in ...
Chemicals like PFOS, PFOA and PFHxS are "for all intents and purposes correctly labeled as forever chemicals," said Christopher Higgins, a leading U.S. expert on PFAS and a distinguished professor ...
The so-called “forever chemicals” − a name attributed to PFAS' centuries-long half-life − are ubiquitous: In addition to drinking water, they are found in everything from non-stick ...
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 ...
Perfluorooctanesulfonic acid (PFOS) (conjugate base perfluorooctanesulfonate) is a chemical compound having an eight-carbon fluorocarbon chain and a sulfonic acid functional group, and thus it is a perfluorosulfonic acid and a perfluoroalkyl substance (PFAS). It is an anthropogenic (man-made) fluorosurfactant, now regarded as a global pollutant.
The chemicals detected were perfluoroalkyl and polyfluoroalkyl substances, or PFAS — a group of manufactured chemicals that break down at an extremely slow rate, meaning they can accumulate over ...
March 2018 The United States Department of Defense's (DoD)'s report to Congress said that test that they conducted showed that the amount of PFAS chemicals in water supplies near 126 DoD facilities, "exceeded the current safety guidelines". [71] The DoD has "used foam containing" PFAS chemicals "in exercises at bases across the country".
