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.

Trump EPA will defend Biden rule forcing polluters to pay for ‘forever chemical’ cleanup
News
17 Sep 2025 | The Hill
The rule in question designated two types of these chemicals as “hazardous substances,” giving the EPA more authority to clean up their contamination and require polluters to pay for it.

Early-life dietary exposure to perfluorooctanoic acid (PFOA) through milk consumption: A systematic review
Science
17 Sep 2025 | J Appl Toxicol
A review of 69 studies (2007–2024) found a wide range of PFOA concentrations in infant formula, commercial milk, and breast milk worldwide, highlighting the urgent need for a more systematic monitoring to protect babies and young children.

A geospatial dataset of PFOS and PFOA occurrence records in China’s multi-media environments
Science
8 Sep 2025 | Nature
PFOS and PFOA, were found widely across China’s water, soil, air, food, and living organisms between 2021 and 2024, with the new geospatial dataset revealing pollution hotspots and recent declines in human blood levels linked to stricter regulations.

Association between perfluoroalkyl and polyfluoroalkyl substances exposure and hypercholesterolemia among US adults: A cross-sectional study
Science
25 Aug 2025 | Ecotoxicol Environ Saf.
Analysis of NHANES 2015–2018 data (n = 2,292) showed that higher serum levels of PFHxS, PFOA, and PFOS were significantly associated with increased prevalence of hypercholesterolemia, with PFHxS as the strongest contributor in mixture models, while combined PFAS exposure consistently elevated risk across multiple statistical approaches.

Mitigating PFAS contamination in the United States: Assessing the impact of California’s legislation from 2018 to 2022 on drinking water quality
Science
23 Aug 2025 | JPHP
California’s 2018–2022 PFAS laws helped cut PFOA and PFOS levels in drinking water by more than half, showing that strong state policies can significantly reduce contamination and serve as a model for national action.
