The proposal has not assessed the use of PFAS in medicines, plant protection products, and biocides because specific regulations apply to those substances (Biocidal Products Regulation, Plant Protection Products Regulation, Medicinal Products Regulation) that have an explicit authorization procedure that focuses on risk for health and the ...
The panel found exposure to certain PFAS was associated with elevated cholesterol levels, and said there was evidence suggesting a probable increase in kidney and testicular cancers among those ...
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 ...
Similarly enhanced processing properties are found in fluorinated ethylene propylene (FEP), the copolymer of tetrafluoroethylene and hexafluoropropylene. [5] However FEP is ten times less capable of withstanding repeated bending without fracture than PFA. [1] Perfluoroalkoxy alkane is used to fabricate tubes to handle aggressive chemicals.
Perfluorodecanoic acid (PFDA) is a fluorosurfactant and has been used in industry. [2] PFDA is a member of the group of polyfluoroalkyl substances (PFAS), more specific is it also a perfluoroalkyl acid (PFAA). PFAS, like PFDA, are man-made and are not naturally occurring in nature.
Perfluorosulfonic acids with six or more perfluorinated carbon atoms, i.e. from perfluorohexanesulfonic acid onwards, are referred to as long-chain. [1] Perfluorooctanesulfonic acid Trifluoromethanesulfonic acid
On Wednesday the FDA announced certain grease-proofing substances containing per and polyfluoroalkyl substances, or PFAS, would no longer be sold for use in food packaging in the U.S.
Fluorosurfactants (PFAS) reduce surface tension by concentrating at the liquid-air interface due to the lipophobicity of polyfluorocarbons. Chlorofluorocarbons are also perfluorinated compounds, many of which were formerly used as refrigerants ( Freon ) until they were implicated in ozone degradation .
