Till de långkedjiga PFAS-ämnen hör PFOA (perfluoroktansyra) och PFOS (perfluoroktansulfonat), som båda består av 8 kol och hör till den så kallade C8-kemin.

EXPOSURE: PFOS is widely distributed around the globe. 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. Polycykliska aromatiska kolväten, även polyaromatiska kolväten eller polyaromater, ofta förkortat PAH av engelska Polycyclic Aromatic Hydrocarbons, är en grupp ämnen som finns i stenkol och petroleum samt bildas vid förbränning av organiskt material [1]. PFOS è in genere commercializzato come sale sodico o potassico. È stato usato soprattutto per materiali come tessuti, tappeti e carta al fine di renderli resistenti a grasso, olio e acqua.

Perfluorooctanoic acid (PFOA) (conjugate base perfluorooctanoate)—also known colloquially as C8—is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock. It is a product of health concern and subject to regulatory action and voluntary industrial phase-outs.
