Exposure characteristics for congeners, isomers, and enantiomers of perfluoroalkyl substances in mothers and infants
Abstract
Prenatal and neonatal exposure to PFASs occur globally but differ among countries. PFOS and PFOA exceed some major environmental toxins in maternal and cord blood. Exposure to PFOS and PFOA has declined since 2000 while trends for others differ. Biomonitoring and research at isomeric and enantiomeric levels are essential. We prefer whole blood over plasma and serum in using blood to assess PFAS exposure.
