PFOS

PFOS is the acronym for perfluorooctane sulfonic acid. PFOS belongs to the per- and polyfluoroalkyl substances - PAFS - associated synthetic chemical alkyl compound. PFAs pose a significant problem to our environment and to our health. PFASs are found in biological samples of all kinds, including serum, skin, and even hair (Piva E et al. 2021). American scientists suspect that over 98% of the US population has one or more detectable PFAS chemicals in their blood. The measurement results show that for the general population, inhalation of PFAS-contaminated indoor air and dust (from furnishings) are the main sources of exposure, in addition to drinking water. But also via fish, meat, milk, eggs and vegetables from contaminated regions (Pitter G et al. 2020; Stubleski J et al. 2017).
