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 ...
PFAS tests that claim to offer results within minutes or at home should be avoided, according to Canter and Professor Mark D. Krahling, an analytical chemist at the University of Southern Indiana ...
Soils also retain more of the chemicals and are a "significant reservoir for PFAS," according to results from a study co-authored by University of Arizona researchers Mark Brusseau and Bo Guo ...
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 ...
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 ...
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 ...
A new EU drinking water directive issued in 2020 adopted PFAS limit values. The limit values are 0.1 μg/L for the sum of 20 PFASs including PFHxS, and 0.5 μg/L for the sum of all PFASs. This directive is binding for all EU member nations. It is a minimum directive, and member states can elect to adopt stricter regulations. [19]
