Typiskt är en kolkedja, där alla väteatomer bytts mot fluoratomer. PFCA hör till gruppen perfluorerade föreningar, även kallade perfluorerade ämnen, USE: PFOS was an important commercial chemical that was used as a fabric protector (3M Scotchguard). PFOS was also used in fire-fighting foams. Its manufacture was stopped in 2002.

It is found in soil, air and water. PFOS is used in many industrial applications including; fire fighting foams, pesticides and consumer applications like surface coatings for carpets, furniture and paper. PFOS is a persistent compound, shows little biodegradation and is globally distributed in living organisms. Vlastnosti. PFOS je považován za perzistentní organickou látku, má silnou schopnost hromadit se v organismu a byl nalezen v tělech ryb, ptáků, savců i lidí. Na zvířatech bylo prokázáno, že může poškodit játra, narušit rozmnožování nebo způsobit poruchu vývoje plodu.Podle epidemiologických studií může u lidí vyvolat rakovinu močového měchýře. Vlastnosti.
