Childhood exposure to per-and polyfluoroalkyl substances during eating activities: Occurrence, exposure, and developmental risk
Science
3 Nov 2025 | J. Environ. Chem. Ecotoxicol.
Children’s feeding bibs and tablecloths were found to contain multiple PFAS, including PFOA, PFNA, and PFOS. Modeled hand-to-mouth exposure during meals was estimated to approach or exceed safety thresholds for infants that potentially disrupt hormone and developmental pathways.

Associations between PFAS in public water system drinking water and serum among Southern California adults
Science
30 Oct 2025 | J Expo Sci Environ Epidemiol
PFAS contamination in drinking water may be a significant contributor to adult serum PFAS levels, even among communities without high level contamination from industrial manufacturing.

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in seafood from Thailand: Levels, geographic distribution, and risk from dietary exposure
Science
27 Oct 2025 | Environ Monit Assess
Short-chain PFAS like PFBS and PFPeA were the most common contaminants found in Thai rivers and irrigation canals, showing that industrial discharge, agriculture, and urban runoff are spreading these persistent chemicals even into areas once considered clean.

Association between maternal exposure to per-and polyfluoroalkyl substances and childhood growth trajectories up to 4 years of age: The Japan environment and children’s study
Science
24 Oct 2025 | Environ Sci Technol
Maternal exposure to PFAS during pregnancy was linked to slower early childhood growth in Japan, with higher PFOS, PFOA, and PFHxS levels associated with lower weight gain and shorter height through age four, suggesting that prenatal PFAS exposure may hinder fetal and postnatal development.

Challenging assumptions: Per-and polyfluoroalkyl substances detected in deep groundwater across southeastern Australia
Science
22 Oct 2025 | ACS ES&T Water
PFAS compounds were detected in deep groundwater across southeastern Australia, including aquifers over 100 meters deep, revealing that even supposedly protected water sources are vulnerable to contamination through surface infiltration, bore leakage, and long-range subsurface transport.

Concentrations of per-and polyfluoroalkyl substances (PFAS) in private well drinking water and serum of individuals exposed to PFAS through biosolids: The Maine Biosolids Study
Science
20 Oct 2025 | Environ. Pollut.
Individuals living near farmland where PFAS-contaminated biosolids were historically applied had elevated PFAS in their private well water and blood, especially PFOA, which showed a strong water-to-serum correlation, demonstrating that biosolids can be a major exposure source and that some people may still have high serum levels even when their current water meets standards.

Changes in the levels and predictors of per-and poly-fluoroalkyl substances in maternal plasma, relative to timelines of EPA PFOA Stewardship
Science
18 Oct 2025 | Environ. Int.
PFOS, PFOA, PFHxS, PFHpS, and Me-PFOSA-AcOH declined over time after EPA’s PFOA Stewardship Program, but other PFAS such as PFNA, PFUnA, PFDeA, PFDoA, and GenX increased especially among non-White mothers, and higher levels were linked to eating fish/shellfish and vegetables, working, and having carpet or pets during pregnancy, showing that policies reduced some PFAS but exposure sources and inequities remain.

PFAS in stormwater control measures: Removal, distribution, and long-term fate
Science
18 Oct 2025 | Water Research
Stormwater systems such as ponds and filters are not designed to remove PFAS, so most PFAS pass through the system, build up in water and sediment over time, and can transform from precursors into more toxic terminal PFAS, making stormwater a growing and often hidden source of PFAS pollution in the environment.

EPA moves to allow more PFAS in drinking water
News
15 Oct 2025 | Environment America
The current U.S. EPA is moving to weaken that rule—including rescinding the limits for four of those PFAS chemicals and delaying limits on the other two.

Comparison of four PFAS mixtures assessment approaches based on extensive tap water and groundwater data
Science
13 Oct 2025 | Environ. Pollut.
Analyzing more than 1,700 U.S. water samples, the study shows that PFAS risk conclusions depend heavily on the method used, simple “sum of PFAS” limits often miss potential health concerns, while toxicity-weighted approaches like EPA-style risk assessment or relative-potency methods flag far more exceedances, frequently driven by PFOA and PFOS.

An unwanted hitchhiker: Assessment of per-and polyfluoroalkyl substances (PFAS) in vehicle cabin air conditioner and engine filters
Science
10 Oct 2025 | Analytical Methods
Car cabin air filters were dominated by diPAPs and long-chain PFCAs (like PFOA, PFNA, and PFDA), showing far higher PFAS levels than engine filters, which mainly contained fluorotelomer sulfonic acids and some PFCAs, indicating that vehicle interiors are a significant source of PFAS exposure.

Wisconsin moves to bring PFAS limits in line with contested federal standards
News
3 Oct 2025 | Wisconsin Public Radio
Environmental advocates are urging state regulators to bring Wisconsin’s PFAS standards in line with federal drinking water standards despite an ongoing legal challenge to the federal rules.

Assessment of arsenic, cadmium, lead, mercury, and per-and polyfluoroalkyl substances concentrations in human milk and infant formula in the United States: A systematic review
Science
23 Sep 2025 | AJCN
A review of U.S. breast milk and infant formulas found that screening for harmful contaminants such as PFAS and metals are limited or outdated, while public health agencies continue to recommend breastfeeding because of its known benefits.

Per- and polyfluoroalkyl substances and the gut microbiota in infants: A scoping review
Science
23 Sep 2025 | Environ Res
PFAS exposure in infants, often through breast milk, maternal blood, or cord blood, was linked to shifts in gut bacteria diversity and changes in metabolism.

The moderating role of vitamin E in the association between PFAS exposures and diabetes risk: Evidence from the NHANES 2017-2018
Science
22 Sep 2025 | Metabolism Open
Analysis of U.S. NHANES 2017–2018 data showed that higher PFAS concentrations, especially PFOS and PFNA, were linked to increased diabetes risk, but vitamin E significantly moderated these effects by reducing PFAS-related elevations in blood glucose, suggesting antioxidant protection is particularly important for older adults and men.
