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 ...
“Contact your state environmental or health agency for detailed advice or to obtain a list of state-certified laboratories using EPA-developed testing methods in drinking water,” agency ...
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".
In 2018, Elsie Sunderland of Harvard's School of Public Health, said the chemical industry's practice of manufacturing ever-increasing numbers of new PFAS compounds − even as they phase out old ...
Perfluorobutanesulfonic acid (PFBS) is a PFAS chemical compound having a four-carbon fluorocarbon chain and a sulfonic acid functional group. It is stable and unreactive because of the strength of carbon–fluorine bonds. It can occur in the form of a colorless liquid or a corrosive solid. [1]
Documents obtained during the civil suits showed chemical giants DuPont and 3M knew of PFAS-related harms to health but hid that information from regulators and the public for decades. Nearly 50 ...
Remediation of per- and polyfluoroalkyl substances refers to the destruction or removal of per- and polyfluoroalkyl substances (PFASs) from the environment. PFASs are a group of synthetic organofluorine compounds, used in diverse products such as non-stick cookware and firefighting foams, that have attracted great concern as persistent organic pollutants.
