Association of serum per-and polyfluoroalkyl substances exposure with leukocyte telomere length in Chinese middle-aged and older adults: Role of genetic susceptibility and healthy diet
Science
16 Jul 2025 | Environ Sci Technol
In nearly 1,500 middle-aged and older Chinese adults, higher blood levels of the PFDA and PFUDA were linked to noticeably shorter telomeres, with the greatest shrinkage in people who also carried aging-related genes and ate a low-quality diet, suggesting these chemicals may speed biological aging.

Levels of serum per- and polyfluoroalkyl substances and association with dyslipidemia in the Korean population
Science
7 Jul 2025 | Ecotoxicol Environ Saf
A large national study of nearly 3,000 Korean adults found widespread PFAS exposure and showed that higher serum concentrations of several compounds, especially PFOA, PFHxS, PFNA and PFDeA, were consistently associated with elevated low-density lipoprotein cholesterol and total cholesterol, implying potential cardiovascular risk and reinforcing the need for stricter regulation.

Association between prenatal exposure to per-and polyfluoroalkyl substances and blood pressure among preschool-aged children: The moderating effect of child-age and the mediating effect of inflammatory cytokine
Science
5 Jul 2025 | Ecotoxicol Environ Saf
Tracking 215 mother-child pairs in China, researchers found that prenatal exposure to common PFAS chemicals was associated with higher diastolic blood pressure in preschoolers, and that inflammatory signals in cord blood partly explained the effect, pointing to a subtle early-life pathway by which PFAS may increase the likelihood of later heart-disease risk.

New CA Law Aimed at Eliminating PFAS from Firefighter Turnout Gear
News
23 Jun 2025 | Firehouse
When firefighters in California head into the flames, they wear special gear to protect them from heat, moisture, smoke and falling materials. But the same equipment meant to keep them safe exposes them to cancer-causing chemicals embedded in their uniforms.

Association between exposure to bisphenols and per- and polyfluoroalkyl substances and behavioral problems among Chinese preschoolers
Science
23 Jun 2025 | Ecotoxicol Environ Saf
A study of 823 Chinese preschoolers found that children with higher combined urine levels of certain BPA-replacement plastics and PFHxS were about twice as likely to show behaviour issues, including hyperactivity, anxiety and conduct problems, highlighting that these may be regrettable substitutes.

Exposure to per-and poly-fluoroalkyl substances and respiratory and skin effects in children and adolescents: A systematic review and meta-analysis
Science
19 Mar 2025 | J Hazard Mater
PFHxS was associated with an increased risk of atopic dermatitis, like eczema, in children, especially when exposure occurred during the prenatal period, suggesting that even early-life exposure to certain PFAS can impact immune and skin health.

Estimating historical PFAS exposures in Ronneby, Sweden using biobanked dried blood spots from newborns
Science
13 Mar 2025 | Environ Res
Researchers used newborn blood samples stored in Sweden's national biobank to show that residents of Ronneby were exposed to toxic PFAS chemicals from contaminated drinking water as early as 1985, with levels rising steadily until 2013 due to fire-fighting foam used at a nearby military airport.

Prenatal per- and polyfluoroalkyl substances and blood pressure trajectories in the New Hampshire Birth Cohort Study
Science
8 Mar 2025 | Int J Hyg Environ Health
Higher prenatal exposure to PFAS is associated with increased blood pressure during pregnancy, even among women without hypertension, suggesting that these chemicals may contribute to adverse maternal and child health outcomes.

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.
