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.

Association between prenatal exposure to per-and polyfluoroalkyl substances and infant anthropometry: A prospective cohort study
Science
4 Mar 2024 | Int. J. Hyg. Environ. Health
Prenatal exposure to PFAS was linked to altered infant growth patterns, with PFNA and PFDoA associated with increased size in females, and PFOA correlated with decreased weight, head, and arm circumference in males, suggesting potential impacts on offspring growth trajectories.

Associations of per- and polyfluoroalkyl substances with maternal metabolic and inflammatory biomarkers in early-to-mid-pregnancy
Science
10 Feb 2024 | Environ Res
Exposure to PFAS during early-to-mid pregnancy was associated with decreased insulin levels, increased HDL cholesterol, and alterations in inflammatory markers, suggesting potential metabolic and inflammatory disruptions that may impact maternal and fetal health.
