Quantitation of linear and branched perfluoroalkane sulfonic acids (PFSAs) in women and infants during pregnancy and lactation
Science
10 Jan 2022 | Environ Int
A linear relation between PFSA concentrations in mothers at pregnancy week 18 and infants at six months was observed, suggesting that pregnancy and lactation are major excretion routes for PFSA, but accumulate in the infant.
