PFAS (per- and polyfluorinated alkyl compounds) are used in C&I applications in many different areas, for example in the manufacturing process of water-repellent textiles or as an additive in fire-fighting foams, but also in aviation processes, the photographic industry and electroplating. Furthermore, they are used as lubricants and impregnating substances as well as in many cosmetics.
