“…[1][2][3][4] The two most common PFAS, perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA), are common groundwater and surface water contaminants and are posing widespread risks to drinking water resources worldwide. 5,6 Given their bioaccumulative and toxic nature, [7][8][9] regulatory criteria for PFOS, PFOA and other PFAS are expected to be established in the near future. For example, Health Canada has proposed a maximum acceptable concentration (MAC) of 600 ng L −1 for PFOS and 200 ng L −1 for PFOA in drinking water.…”

“…PFASs have been widely applied in various fields involving people's daily consumer goods, business, and industry, such as surfactants, fire retardants, additives, lubricants, carpet cleaners, paper coatings, and cosmetics (Sims et al, 2022). PFASs have also been widely used in pesticides (herbicides, insecticides, etc.)…”

“…Therefore, PFOS, perfluorooctanoic acid (PFOA), and related compounds were listed as priority pollutants in the International Stockholm Convention (Chen et al, 2022). In the past decades, shortchain PFASs or no-fluorinated substances have been recommended by global manufacturers instead of short-chain PFASs (Sims et al, 2022;Tang et al, 2022).…”

“…PFCAs differ greatly from other well-studied organic pollutants (e.g., polychlorinated biphenyl) as they tend to have low octanol/water partition coefficients (logK ow ) resulting in lower affinity to sediments and soils and higher water solubility (Davis et al, 2007). Consequently, both PFOA and PFHxA are frequently detected from bodies of waters around the globe (Sun et al, 2018;Muir and Miaz, 2021;Sims et al, 2022), where they end up directly from point-sources or indirectly as a wet or dry fall (Knepper et al, 2012). So far, PFOA is generally detected more often, and in higher concentrations, from the surface waters compared to PFHxA (Eschauzier et al, 2012).…”
