The Relationship Between Maternal Exposure to Endocrine-Disrupting Chemicals and the Incidence of Congenital Heart Diseases: A Systematic Review and Meta-Analysis
Science
16 Dec 2024 | Metabolites
PFAS can disrupt the endocrine system by binding to nuclear hormone receptors such as estrogen and androgen receptors, potentially interfering with hormone signaling pathways that regulate reproductive, metabolic, and developmental processes. Here, a model was developed to predict how strongly different PFAS bind to these receptors.

Prenatal exposure to per- and polyfluoroalkyl substances, fetoplacental hemodynamics, and fetal growth
Science
20 Oct 2024 | Environ Int
Legacy PFAS exposure during pregnancy may be linked to reduced fetal growth, but the effects of next-generation PFAS and PFAS mixtures are less clear, with further research needed to understand their impact on fetoplacental blood flow.

It’s too soon to stop studying the potential effects of PFAS on human health
Science
9 Aug 2024 | Nature
Despite positive signs regarding the decreasing presence of specific PFAS in the blood of sampled humans, we do not know enough about this broad class of substances to justify stopping research on their toxicity.

Removing PFAS from public water systems will cost billions and take time – here are ways you can filter out harmful ‘forever chemicals’ at home
News
13 May 2024 | WMNF
Every five years, the EPA is required to choose 30 unregulated contaminants to monitor in public drinking water systems. Right now, 29 of those 30 contaminants are PFAS. The tests provide a sense of just how widespread PFAS are in water systems and where.

Sub-acute exposure of male guppies (Poecilia reticulata) to environmentally relevant concentrations of PFOA and GenX induces significant changes in the testis transcriptome and reproductive traits
Science
26 Apr 2024 | Environ Int
Exposure of male guppies to environmentally realistic levels of a legacy PFAS and its replacement compound (GenX) resulted in altered reproductive traits, including changes in sexual behavior and sperm motility, as well as gene expression related to immune regulation. These changes highlight the potential adverse effects of PFAS on behavior, fertility, and immunity in fish populations.
