Sweat-amplified dermal transfer and combined toxicity of per- and polyfluoroalkyl substances and organophosphate esters mixtures in children's textiles
Science
8 Sep 2025 | Sci Total Environ
Sweating was found to increase the dermal transfer of PFAS and organophosphate esters from children's clothing by over 1000-fold, leading to chemical levels on the skin that exceed regulatory limits and cause measurable toxic effects in human skin cell tests.
