Effect modification by maternal vitamin D status in the association between prenatal exposure to per- and polyfluoroalkyl substances and neurodevelopment in 2-year-old children
Science
5 Mar 2024 | Environ Int
In a Chinese birth cohort, researchers investigated how prenatal exposure to PFAS affects childhood neurodevelopment, finding that while PFAS exposure was linked to lower language scores and increased risk of delay overall, the impact varied based on maternal vitamin D levels.

Occurrence, partitioning and transport of perfluoroalkyl acids in gas and particles from the southeast coastal and mountainous areas of China
Science
5 Dec 2022 | Environ Sci Pollut Res Int.
The longer the fluorinated carbon chain length of the PFAA, the more the PFAA tended to exist in the particulate phase, and PFAS in China can be widely spread through the atmosphere due to winter monsoon winds.
