Perfluoroalkyl substances are globally distributed, anthropogenic contaminants.
Perfluoroalkyl acids (PFAs) are synthetic, perfluorinated, straight- or branched-chain organic acids characterized by a carboxylate or sulfonate moiety.
Surface treatment applications to provide soil, oil and water resistance to personal apparel and home furnishings (e.g. carpet cleaner and Goretex®). on paper products to provide grease, water, and oil resistance to plates, food containers, bags, and wrap (Teflon ®) aqueous film-forming foams (AFFF) for fire-fighting,
