Dermal bioaccessibility of perfluoroalkyl substances from household dust; influence of topically applied cosmetics
6 Sep 2023 | Environ Res
In vitro testing revealed that dermal contact with dust may be an important exposure pathway for many PFAS, and that personal care products like sunscreen and moisturizer may change how the body is exposed to PFAS through the skin.
Comparative study of Per-and Polyfluoroalkyl substances (PFAS) removal from landfill leachate
31 Aug 2023 | Chemosphere
Foam fractionation and anion exchange resin treatment were the most cost-effective methods for removing >90% of PFOA and PFOS, while nanofiltration was the only method practical for short-chain PFAS removal.
