Journal of Toxicology and Environmental Health. Part B, Critical Reviews, 2021 Per- and polyfluorinated substances (PFAS), ubiquitously present in the environment and biota, are transferred to the fetus via the placenta. PFAS can be distinguished, among other things, by their different carbon chain lengths and functional groups ...
