Context of the study. There is a lack of information on the pollution caused by perfluorooctane sulfonic acid (PFOS) in the aquatic wildlife of Western Europe. The degree of PFOS pollution in the Western Scheldt is particularly interesting, given its importance as a nursing area for wild life, and the presence of important chemical plants in Antwerp (upstream of the Western Scheldt).
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 –.
