Associations between prenatal exposure to per- and polyfluoroalkyl substances and plasma immune molecules in three-year-old children in China
Science
27 Jul 2024 | Toxicol Appl Pharmacol
Prenatal exposure to PFAS significantly affects immune molecule levels in three-year-old children, with specific PFAS linked to increases in interleukins and Eotaxin-3, which help regulate the immune system, highlighting the need to understand environmental impacts on early immune development.

Prenatal Exposure of PFAS in Cohorts of Pregnant Women: Identifying the Critical Windows of Vulnerability and Health Implications
Science
25 Jul 2024 | Environ. Sci. Technol.
From 2018 to 2020, a prenatal PFAS exposure study in pregnant women and their newborns showed a decline in older PFAS but an increase in emerging PFAS and highlighted the third trimester as a critical window affecting birth weight and length.

Occurrence of 80 Per and polyfluorinated alkyl substances (PFAS) in the Muscle and Liver tissues of Marine Mammals of the St. Lawrence Estuary and Gulf, Quebec, Canada
Science
10 Jun 2024 | Front. Environ. Chem.
Marine mammals from the St. Lawrence Estuary and Gulf, such as dolphins and porpoises, were found to have high levels of PFAS in their tissues, with the white-sided dolphin showing the highest average concentrations—39 ng/g in muscle and 334 ng/g in liver—while species like the harp seal had much lower levels, emphasizing the need for stronger regulations to protect these vulnerable animals.

Association of co-exposure to organophosphate esters and per- and polyfluoroalkyl substances and mixture with cardiovascular-kidney-liver-metabolic biomarkers among Chinese adults
Science
4 Jun 2024 | Ecotoxicol Environ Saf
Exposure to common environmental contaminants like organophosphate esters and PFAS, especially PFHxS and PFNA, is associated with disruptions in liver function and cholesterol levels, suggesting potential risks for chronic diseases due to their widespread presence in the human body.

Per- and polyfluoroalkyl substances (PFAS) and fetal growth: A nation-wide register-based study on PFAS in drinking water
Science
8 May 2024 | Environ Int
A nationwide study in Sweden found no clear link between maternal exposure to certain PFAS during pregnancy and newborn birthweight or risk of being small-for-gestational-age, but did find a slight increase in the risk of being large-for-gestational-age, particularly associated with PFOS.

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.
