New Findings Show Prenatal PFAS Exposure Is More Widespread Than Previously Realized

A non-targeted screening of umbilical cord blood from 120 newborns (2003–2006) identified 42 PFAS compounds, revealing broader prenatal exposure than previously known. The researchers developed PFAS-omics burden scores to estimate total fetal PFAS burden and found no difference by maternal parity, underscoring the need for improved screening and more research on health effects tied to exposure.
