Evaluation of per- and polyfluoroalkyl substances (PFAS) in landfill liquids from Pennsylvania, Colorado, and Wisconsin
Science
19 Mar 2024 | Chemosphere
Average PFAS levels in landfills from Pennsylvania, Colorado, and Wisconsin were 6,900, 22,000, 280, and 260 ppt in leachate, gas condensate, stormwater, and groundwater, respectively, with variations attributed to landfill design and local climate and higher PFAS levels in leachate exposed to open air and in groundwater near landfills without bottom liners.

Prenatal exposure to mixtures of per- and polyfluoroalkyl substances and organochlorines affects cognition in adolescence independent of postnatal exposure
Science
5 Mar 2024 | Int J Hyg Environ Health
This study investigated the cognitive effects of prenatal exposure to PFAS and organochlorines, finding that higher prenatal exposure to these chemicals, particularly PFHxS and PFNA, is associated with improved sustained and selective attention during adolescence, regardless of exposure levels at adolescence. However, the authors suggest the results should be interpreted with caution due to limited understanding of biological pathways and prior studies showing neurotoxic effects from PFAS.

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.
