March 2018 The PFAS Expert Health Panel on PFAS submitted their commissioned report to the Australian government. [ 89 ] 14 May 2018 Politico gained access to the email chains and published the story in May, saying that Scott Pruitt's EPA had worked with the Trump administration to block the publication of the Agency for Toxic Substances and ...
[13] [18] [19] [8] Since PFAS compounds are highly mobile, they are readily absorbed through human skin and through tear ducts, and such products on lips are often unwittingly ingested. [20] Due to the large number of PFAS, it is challenging to study and assess the potential human health and environmental risks; more research is necessary and ...
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.
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]
Perfluorooctanesulfonamide (PFOSA) is a synthetic organofluorine compound.It is a fluorocarbon derivative and a perfluorinated compound, having an eight-carbon chain and a terminal sulfonamide functional group.
Perfluorosulfonic acids (PFSAs) are chemical compounds of the formula C n F (2n+1) SO 3 H and thus belong to the family of perfluorinated and polyfluorinated alkyl compounds (PFASs).
Trifluoroacetic acid is a widely employed acid, used for example in the synthesis of peptides.Its esters are useful in analytical chemistry. Longer-chain perfluoroalkyl carboxylic acids, e.g. with five to nine carbons, are useful fluorosurfactants and emulsifiers used in the production of polytetrafluoroethylene (Teflon) and related fluoropolymers.
The resulting lab report linked per- and polyfluoroalkyl substances (PFAS, also known as "forever chemicals") to the turf. Six former Phillies who played at Veterans Stadium have died from glioblastoma , an aggressive brain cancer: Tug McGraw , Darren Daulton , John Vukovich , Johnny Oates , Ken Brett , and David West .
