Per- and polyfluoroalkyl substances ( PFAS [1] or PFASs [2]) are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain; there are 7 million such chemicals according to PubChem. [3] PFAS came into use after the invention of Teflon in 1938 to make fluoropolymer coatings and products ...
PFAS, short for perfluoroalkyl and polyfluoroalkyl substances, are a large family of chemicals that have been used in a wide variety of products and industries because of their unique stain- and ...
PFAS then accumulates the biomass in fish, wildlife, ecosystems and humans. Two of the primary compounds of concern, PFOA and PFOS, pose a host of potential risks, particularly to children and ...
Buy fewer products with PFAS in them. In addition to switching to purified water, you can limit PFAS exposure by avoiding: Stain-resistant clothing, carpeting and furniture.
PFAS compounds and their derivatives are widely used in many products from water resistant textiles to fire-fighting foam. [4] [1] PFAS are commonly found in every American household in products as diverse as non-stick cookware, stain resistant furniture and carpets, wrinkle free and water repellant clothing, cosmetics, lubricants, paint, pizza ...
Per-and polyfluoroalkyl substances are found in thousands of products most Americans use or come into contact with daily, such as: Food containers that have PFAs are waterproof and grease-proof ...
Perfluorooctanesulfonic acid ( PFOS) ( conjugate base perfluorooctanesulfonate) is a chemical compound having an eight- carbon fluorocarbon chain and a sulfonic acid functional group and thus a perfluorosulfonic acid. It is an anthropogenic (man-made) fluorosurfactant, now regarded as a global pollutant.
Perfluorodecanoic acid (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. Over the last decades they have been used in consumer products and industrial applications.
