In December of 2025, PRCCEH members Dr. Kristen Lyall and Dr. Anneclaire J De Roos collaborated with four other authors to publish a study, which evaluated differences in exposure to 14 Per- and polyfluroalkyl substances (PFAS) by sociodemographic factors amongst pregnant women in the U.S. The study found that higher levels of some PFAS were observed by race, ethnicity, and education. These findings document the continued widespread PFAS exposure in the United States and highlight that ongoing biomonitoring is necessary in understanding changing exposure patterns across racial, ethnic, and socioeconomic groups.
