Per-and polyfluoroalkyl substances

Per- and polyfluoroalkyl substances (PFAS) are persistent, bioaccumulative chemicals widely used in industry and consumer products, and now detected across environmental media and human populations. This study assesses the societal costs of PFAS pollution in the European Economic Area (EEA) under four hypothetical exposure scenarios: 1) business as usual (BAU) for emissions; 2) full compliance with the Drinking Water Directive (DWD); 3) full compliance with Environmental Quality Standards (EQS); and 4) a total ban on PFAS production and use.

             Per- and polyfluoroalkyl substances (PFAS) are a diverse group of synthetic compounds widely used for their dual hydrophobic and lipophobic properties. They comprise more than 4700 CAS-registered compounds according to the OECD and have been used intentionally in nonstick, grease-and waterproof, and stain-resistant consumer products, particularly food packaging materials. PFAS are inherently persistent, and many are mobile, bio-accumulative, and toxicity to a wide array of organisms, making them emerging contaminants of concern.
