PFAS concentrations in the blood of Danish surfers
Science
20 Jan 2025 | Int J Hyg Environ Health
PFAS concentrations in the blood of Danish surfers were measured, revealing no significant relationship between the amount of time spent surfing and higher PFAS levels, but male sex and eating meat from free-ranging animals were found to be potential risk factors for increased exposure.

[Press Release] Attorney General Bonta Co-leads Amicus Brief Defending Nationwide PFAS “Forever Chemicals” Drinking Water Standards
Policy
17 Jan 2025
California Attorney General Rob Bonta today co-led a coalition of 17 states in filing an amicus brief in the U.S. Court of Appeals for the D.C. Circuit defending a U.S. EPA rule establishing the first nationwide drinking water standards for certain toxic PFAS, also known as “forever chemicals,” under the Safe Drinking Water Act.

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.
