Per-and polyfluoroalkyl substances in reusable feminine hygiene products
22 Jul 2025 | Environ. Sci. Technol. Lett.
59 reusable menstrual products from North America, South America, and Europe were found to contain PFAS in all items, with period underwear and reusable pads most often intentionally treated. Availability of PFAS-free options suggests thatPFAS aren’t necessary. More research is needed on dermal exposure.
Human exposure to PFASs in a contaminated area: Associations between water and serum levels
21 Jul 2025 | Chemosphere
In Italy’s PFAS-polluted Veneto region, scientists found that residents’ blood PFAS levels mirror contamination in their tap and well water, with most people exceed the European Food Safety Authority’s safe weekly intake.
Assessment of sealants for the mitigation of PFAS leaching from contaminated concrete
21 Jul 2025 | J. Hazard. Mater.
Laboratory tests on six readily available concrete sealants showed that an epoxy coating is the most effective barrier to PFAS leaching from contaminated runways and pads; researchers recommend using a combination of surface and penetrating sealants for rapid, on-site pollution control.
[Viewpoint] Specific ambient PM 2.5-bound perfluoroalkyl and polyfluoroalkyl substances (PFAS): A Prominent human health risk issue that deserves Attention?
18 Jul 2025 | Environ Sci Technol
PFAS are found to attach to fine air pollution, including carcinogens like PFOA and PFOS, making even low levels a health concern and warranting closer science and policy attention.
Occurrence and maternal transfer of per-and polyfluoroalkyl substances (PFAS) in pregnant sharks from Florida coastal waters
17 Jul 2025 | Environ. Sci. Technol.
PFAS chemicals were found in pregnant sharks from Florida waters and shown to pass from mothers to their 101 developing embryos during gestation, with longer chain types such as PFOS building up the most in embryo tissues.
Phthalates, bisphenols and per-and polyfluoroalkyl substances migration from food packaging into food: a systematic review
17 Jul 2025 | Rev Environ Health
A review of 67 studies shows that hormone-disrupting chemicals such as phthalates, bisphenols and PFAS frequently leach from everyday food packaging, highlighting the need for safer materials.
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.
