PFAS are a large, complex, and ever-expanding group of manufactured chemicals that are widely used to make various types of everyday products. For example, they keep food from sticking to cookware, make clothes and carpets resistant to stains, and create firefighting foam that is more effective. PFAS are used in industries such as aerospace, automotive, construction, electronics, and military.

PFOA and perfluorooctanesulfonic acid (PFOS) have been estimated to be in every American person’s blood stream in the parts per billion range, though those concentrations have decreased by 70% for PFOA and 84% for PFOS between 1999 and 2014, which coincides with the end of the production and phase out of PFOA and PFOS in the US. Per- and polyfluoroalkyl substances (PFASs, also perfluorinated alkylated substances) are synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain. As such, they contain at least one perfluoroalkyl moiety, –C n F 2n –. According to OECD, there are at least 4730 different PFASs. 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.

PFOSA, a persistent organic pollutant, was an ingredient in 3M 's former Scotchgard formulation from 1956 until 2003, and the compound was used to repel grease and water in food packaging along with other consumer applications. It breaks down to form perfluorooctane sulfonate (PFOS).

Chemical compound. Perfluorooctanesulfonic acid ( PFOS) ( conjugate base perfluorooctanesulfonate) is an anthropogenic fluorosurfactant and global pollutant. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents.

Hudiksvall ligger längs kusten, längst inne i Hudiksvallsfjärden, vid E4 cirka 80 km söder om Sundsvall och cirka 130 km norr om Gävle. PFAS eller högfluorerade ämnen är ett samlingsnamn för en grupp organiska ämnen som alla består av en kolkedja där väteatomerna är helt eller delvis utbytta mot fluoratomer. Det är en stor och komplex grupp på mer än 4700 identifierade ämnen med varierande egenskaper och bred användning i samhället.
