Evaluating Dermal Absorption of Perfluorooctanoic Acid (PFOA) and Implications for Other Per-and Polyfluoroalkyl Substances (PFAS)
Science
6 Jan 2025 | Regul Toxicol Pharmacol
PFOA was found to have low dermal absorption compared to other harmful chemicals, with these authors selecting a 1.6% absorption rate as the published value most likely to be accurate, suggesting that ingestion remains a higher exposure pathway compared to skin contact.
