Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) compounds are known as Perflor grouped chemicals (PFCs).
PFOS is widely used as a protective coating of materials used in the carpet, textile and leather industries. It is also used in various household and industrial cleaning products. PFOA is mainly used as a fluoropolymer in the electronics, textile industry and non-stick cookware production. PFC compounds are stable, heat insensitive and surfactants that reject water and oily compounds. PFOS and PFOA compounds and their derivatives may spread to the environment. PFC compounds are carcinogenic (liver, thyroid, testis, pancreas, breast). Power-aware liver and thyroid effects may lead to death, delayed growth and maturation for child development, behavioral disorders due to unrecognized behavior, and consequent effects on birth, as well as birth defects.
