Among these compounds, perfluorooctane sulfonic acid (PFOS)and perfluorooctanoic acid (PFOA) have received the most atten-tion for many years, due to their adverse effects on human health.However, more recently, a range of other PFAS received increas-ing attention because they are produced as alternatives for PFOSand PFOA, as intermediates in PFAS production, as by-productsor as (bio)degradation products. Therefore, additional monitor-ing focused not only on PFOS and PFOA, but also on other PFAS.These include perfluorocarboxylates (PFCAs) and perfluorosul-fonates (PFSAs) with different chain lengths (typically betweenC4 and C14), fluorotelomer carboxylic acids (FTCAs) and non-ionic(volatile) compounds such as fluorotelomer alcohols (FTOHs), per-fluorosulfonamide (PFOSA) and N-substituted sulfonamides [3].However, the transformation of alcohols and sulfonamides in acidsis fairly rapid and, they have been found only in the atmosphere
