PFAS then accumulates the biomass in fish, wildlife, ecosystems and humans. Two of the primary compounds of concern, PFOA and PFOS, pose a host of potential risks, particularly to children and ...
PFAS in contaminated soil and irrigation water can end up in food. The European Union and countries like Australia and New Zealand have already evaluated and established "tolerable daily intakes ...
Fire-retardant foam, which contained PFAS compounds for decades, often found use at military bases and airstrips, causing costly pollution to nearby water sources. The U.S. Department of Defense ...
Perfluorooctanoic acid ( PFOA; conjugate base perfluorooctanoate; also known colloquially as C8, for its 8-carbon chain structure) is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock. PFOA is considered a surfactant, or fluorosurfactant, due to its ...
PFAS contamination has also resulted in disruptions to the food supply, such as closures and limits on fishing. Shorter fluorosurfactants may be less prone to accumulating in mammals; there is still some concern that they may be harmful to both humans and the environment, Suppression of information on health effects
Perfluorobutanesulfonic acid ( PFBS) is a PFAS chemical compound having a four-carbon fluorocarbon chain and a sulfonic acid functional group. It is stable and unreactive because of the strength of carbon–fluorine bonds. It can occur in the form of a colorless liquid or a corrosive solid. [1] Its conjugate base is perfluorobutanesulfonate ...
Of those, 982 were identified as contaminated with PFAS compounds, with 299 having detections of total PFAS over 70 parts per trillion, the EPA's previous lifetime health advisory level set in ...
10 January 2018 According to the U.S. Department of Health & Human Services's Agency for Toxic Substances and Disease Registry (ATSDR) website, which was last reviewed on10 January 2018, the "health effects of PFOS, PFOA, PFHxS, and PFNA have been more widely studied than other per- and polyfluoroalkyl substances (PFAS). Some, but not all ...
