Ten years of PFOS and PFOA human biomonitoring in Italy: Exposure levels and determinants of exposure
Science
14 Mar 2025 | Chemosphere
PFAS exposure in the Italian population has declined over ten years for PFOA but not for PFOS, with higher levels observed in men, individuals in urbanized areas, and those with higher education or occupational skill levels, while proximity to PFAS-emitting industries remains the strongest predictor of elevated exposure.

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.

Bone cell differentiation and mineralization in wild-type and osteogenesis imperfecta zebrafish are compromised by per-and poly-fluoroalkyl substances (PFAS)
Science
17 Jan 2025 | Sci Rep
Exposure to PFOS, PFOA, and PFHxA harmed bone development in zebrafish, disrupting bone cell growth, increasing cell death, and affecting fat storage, with more severe effects in the zebrafish with pre-existing bone issues.

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.
