Skin Permeability of Perfluorocarboxylic Acids Using Flow-Through Diffusion on Porcine Skin
Science
7 Oct 2024 | Toxics
Using porcine skin, PFBA showed higher skin permeability compared to other PFAS, and although overall absorption was low, these chemicals can accumulate in the skin, potentially acting as a long-term reservoir.

Prenatal exposure to PFAS and the association with neurobehavioral and social development during childhood
Science
25 Sep 2024 | Int J Hyg Environ Health
Prenatal exposure to PFAS shows mixed effects on children's neurobehavioral and social development markers like behavioral issues and anxiety, but strong associations were not found in this population with low PFAS exposure and depended on the children’s sex, type of PFAS, and developmental outcome.

Multimedia and Full-Life-Cycle Monitoring Discloses the Dynamic Accumulation Rules of PFAS and Underestimated Foliar Uptake in Wheat near a Fluorochemical Industrial Park
Science
18 Sep 2024 | Environ. Sci. Technol.
PFAS contamination near a major industrial park in China, particularly from airborne deposition, has led to significant accumulation in soil and wheat, with spray irrigation increasing PFAS absorption in wheat compared to flood irrigation. Local residents have high exposure risks through wheat consumption and air inhalation.
