Occurrence and tissue distribution of per- and polyfluoroalkyl substances (PFAS) in fishes from waterbodies with point and non-point sources in Massachusetts, USA

17 Jul 2025 | Aquat Toxicol

In Massachusetts lakes and rivers, fish near known PFAS sources had much higher PFAS levels, especially PFOS. PFAS levels rose between 2020 and 2022, concentrating in blood more than in liver or muscle, and with lab tests showing signs of inflammation and other stress.

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

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.

Characterization and health risk assessment of chemical and microbial pollutants in particulate matter from dust prone regions

14 Jul 2025 | Scientific Reports

Researchers in Sharjah, UAE, detected trace levels of PFAS in desert dust, showing that wind-blown sand can spread these persistent pollutants through the air and spotlighting inhalation as an overlooked exposure route that arid-city air-quality programs need to monitor.

PFAS in pelagic Sargassum: A growing concern for the Mexican Caribbean coastline

14 Jul 2025 | J. Hazard. Mater.

Scientists report the first evidence that the vast, floating seaweed Sargassum, is able to uptake and transport PFAS across vast distances, making the blooms both an expensive pollution vector and a potential tool for cleaning contaminated seawater.

PFAS exposure, mental health, and environmental justice in the United States: Impacts on marginalized communities

9 Jul 2025 | Int. J. Environ. Res. Public Health

PFAS exposure was associated with increased anxiety, depression, cognitive decline, and chronic stress in marginalized communities, highlighting racial and socioeconomic disparities in contamination and mental health impacts across the U.S.

Smoldering treatment of PFAS: Investigation of mass balance and volumetric scale up for field implementatio

8 Jul 2025 | ACS Omega

Engineers have conducted a proof-of-concept study to show that a self-sustaining “smoldering” treatment, enhanced with calcium oxide, can scale from lab columns to 10 m³ soil piles and destroy >99.9 % of PFAS while trapping the released fluorine as benign calcium fluoride, pointing to an energy-efficient, potentially field-ready solution for cleaning contaminated fire-training sites.

Levels of serum per- and polyfluoroalkyl substances and association with dyslipidemia in the Korean population

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

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.

Analysis of legacy PFAS and potential precursors in curtain, sofa, and carpet fabric samples

2 Jul 2025 | Sci Total Environ

A European survey of 30 carpets, curtains, and sofa fabrics collected in 2023 found that household textiles can carry unexpectedly high levels of PFAS, often dominated by newer short-chain compounds, confirming these everyday items as a notable indoor source of PFAS exposure.

Exposure to per-and polyfluoroalkyl substances (PFAS) in healthcare: Environmental and clinical insights

1 Jul 2025 | Life

A review highlights that PFAS-containing plastics in many medical devices can leach into patients, especially vulnerable children, and urges safer materials, routine monitoring, and stronger regulation to curb this hidden exposure.

What people in the United States are asking about per and polyfluoroalkyl substances in their drinking water based on online search behaviors

1 Jul 2025 | J. Environ. Health.

Analysis of U.S. Google searches show most people asking about PFAS in drinking water are seeking practical ways to reduce exposure, providing insight into what type of information should be the focus of public health messaging.

Temporal changes in per and polyfluoroalkyl substances and their associations with type 2 diabetes

1 Jul 2025 | Sci Rep

A 30-year Norwegian study found that blood levels of PFHpA, PFNA, PFHxS and PFHpS increased at a faster rate in people who later developed type 2 diabetes, indicating that exposure to these pollutants may play a role in the disease.

Development of chemical categories for per- and polyfluoroalkyl substances (PFAS) and the proof-of-concept approach to the identification of potential candidates for tiered toxicological testing and human health assessment

30 Jun 2025 | Comput Toxicol

US EPA researchers mapped about 15,500 PFAS, grouped them into 128 structural categories, and pointed out the biggest data gaps—so regulators can target testing the most concerning types instead of addressing each chemical one by one.

Per- and polyfluoroalkyl substances, genetic factors, and sleep health in reproductive-aged women: a cross-sectional study of the Shanghai Birth Cohort.

30 Jun 2025 | Environ Int

A Shanghai study of nearly 1,000 women found that higher blood levels of PFAS, particularly newer chlorinated alternatives and PFOS isomers, were linked to increased snoring, with genetics magnifying the risk.

Leachability of per-and polyfluoroalkyl substances in metal recycling streams

25 Jun 2025 | J. Hazard. Mater.

Automotive shredder residue, the mixed waste left after salvaging metal from cars, contains a suite of PFAS compounds that lab tests show readily leach into water, making it a persistent source of contamination in storm-water runoff and landfill leachate.
