Seamounts create local hotspots of per-and polyfluoroalkyl substances in the oligotrophic open ocean
4 Aug 2025 | Progress in Oceanography
Scientists discovered that waters above Pacific seamounts hold per- and polyfluoroalkyl substances at concentrations about 40 % higher than nearby open ocean, with the mid-depth mesopelagic layer especially rich in newer short-chain PFAS, showing these undersea mountains act as unexpected hotspots.
High-resolution mass spectrometry for extended PFAS surveillance in food: Combining suspect and non-targeted approaches
29 Jul 2025 | Food Chemistry: X
Using high-resolution mass-spectrometry, scientists examined 58 foods from Europe and North Africa and detected 17 known PFAS plus four previously overlooked fluorinated compounds, including the short-chain PFPrA found in almost half the samples.
Pygoscelis penguins as indicators of perfluoroalkyl substances pollution and global health risks - case study from King George Island (Western Antarctic)
29 Jul 2025 | Environ Res
Scientists found that guano from penguins nesting near research stations on King George Island contained detectable PFAS chemicals (PFOS and PFPeS) while colonies farther away did not, revealing that even remote Antarctic wildlife is affected by localized human pollution.
CdIn2S4 micro‐pyramids for reductive photocatalytic degradation of perfluorooctanesulfonic acid
25 Jul 2025 | Small
CdIn₂S₄ micro-pyramids achieved rapid and efficient photocatalytic degradation of PFOS under visible light by promoting reductive defluorination, offering a promising approach for PFAS remediation in water, in this proof-of-concept study.
Per- and polyfluoroalkyl substance concentrations during pregnancy and at birth and risk of childhood acute lymphoblastic leukemia
25 Jul 2025 | Environ Res
Researchers analyzing blood samples from California newborns and their mothers found that babies with high levels of MeFOSAA, and to a lesser degree mothers with elevated pregnancy levels, faced roughly double the risk of developing childhood leukemia.
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.
