Reevaluating PFAS exposure risks from marine fish
18 Dec 2025 | Science
A global modeling analysis finds that legacy PFAS exposure from marine fish may now be low for most countries due to production phaseouts, yet remains higher in places with very high seafood intake such as Greenland and Denmark, offering important insight for refining fish consumption guidance and noting where potential risk persists.
Formation of perfluorocarboxylic acids (PFCAs) from the incomplete thermal decomposition of perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA
16 Dec 2025 | ACS ES&T Air
PFOS and PFOA thermal treatment may consistently produce multiple perfluorocarboxylic acids and volatile fluorinated byproducts at suboptimal temperatures despite near-complete parent destruction, highlighting potential emissions concerns and uncertainties about the specific formation pathways.
Determination of analytical interferences for 4:2 fluorotelomer sulfonic acid in multiple agricultural matrices
16 Dec 2025 | J Agric Food Chem
Naturally occurring oxidized fatty acids in crops were found to generate the same mass-spectrometric signals as 4:2 FTS, which could lead to potentially inaccurate PFAS measurements in agricultural products and may warrant careful method evaluation before results are reported.
Childhood exposure to per-and polyfluoroalkyl substances in educational environments: Arising from stationery and implications for health
15 Dec 2025 | J. Environ. Chem. Ecotoxicol.
Several products purchased in China released measurable PFAS including precursors that increased after oxidation and maximum estimated intake from hand to mouth contact with some pen grips approaching the European Food Safety Authority tolerable intake for children.
Mediating role of proteomics in the association between per-and polyfluoroalkyl substance exposure and blood pressure in youth
15 Dec 2025 | Environ Pollut.
PFOA, PFNA, PFOS, PFHxS, and PFHpS, exposure may be associated with higher blood pressure in youth through protein changes (particularly galectin-3) involving inflammatory and scarred tissue.
A Dominating Role of Functional Groups in Short-Chain Per- and Polyfluoroalkyl Substance (PFAS) Accumulation by Fruiting Plants
11 Dec 2025 | Environ Sci Technol
Tomato plants were found to preferentially move short-chain PFAS with carboxylic acid groups into fruits while sulfonic acid PFAS are largely retained in roots and leaves, which could influence potential dietary exposure and guide crop choices in contaminated areas.
Co-exposure to PFAS and hydroxylated PCBs is associated with increased odds of multiple sclerosis
11 Dec 2025 | Environ Int
Swedish adults with background exposure who had higher serum levels of PFOS and PCB breakdown products may face increased odds of developing multiple sclerosis, with the strongest associations observed at higher exposure ranges after accounting for lifestyle and genetic differences.
Occurrence and risk assessment of per-and polyfluoroalkyl substances (PFAS) in wastewater and drinking water in Colombia
8 Dec 2025 | ACS ES&T Water
Several PFAS, particularly PFHxA and PFHpA, may present potential health concerns in Colombian drinking water since their estimated intake levels surpassed the United States Lifetime Health Advisory screening level for mixtures.
Unravelling the chemistry of PFAS transfer from packaging to food
8 Dec 2025 | TIFS
PFAS used in paper, paperboard, compostable, and plastic food-contact materials may migrate into food through diffusion, partitioning, and degradation of polymer-bound PFAS, suggesting that these packaging materials may act as overlooked sources of dietary PFAS exposure and warrant closer regulatory attention.
Investigating anaerobic digestion microbiome resilience to high PFOA and PFOS mixtures during cometabolism
8 Dec 2025 | Bioresour. Technol.
High levels of PFOA and PFOS may interfere with how microbes create biogas during anaerobic digestion, which is important for waste-treatment policy because it suggests these chemicals can disrupt sludge processing while showing no clear signs of degradation.
Assessing the impact of perfluoroalkyl substances on liver health: A comprehensive study using multi-donor human liver spheroids
8 Dec 2025 | Environ. Int.
PFHxS, PFOA, PFOS, and PFNA may interfere with liver function in different ways depending on the specific chemical and the sex of the donor cells, potentially contributing to fat buildup in the liver, weakened immune activity, and molecular changes linked to cancer development.
Per-and polyfluoroalkyl substances (PFAS) in fruit flies: Environmental surveillance and hazard characterization of “forever chemicals”
7 Dec 2025 | Environ. Sci. Technol. Lett.
PFAS including PFOA, PFOS, and GenX may disrupt conserved metabolic, neural, reproductive, and developmental pathways in fruit flies at doses that overlap with environmentally relevant human exposures, suggesting shared toxicity mechanisms and possible transgenerational effects.
Development and validation of an LC-MS/MS method for simultaneous determination of 39 PFAS in soil samples: applications to playgrounds in Attica, Greece
4 Dec 2025 | Anal Bioanal Chem
An optimized research method was found to be a useful tool for environmental and public-health decision making by reliably detecting 39 PFAS in playground soils, and the results suggest that some PFAS levels may potentially exceed a precautionary child-health screening value of about 100 ng per kg of body weight per day.
Evaluation of fluorochemical leaching from lithium-ion batteries under simulated solid waste landfill conditions
3 Dec 2025 | Environ. Sci. Technol.
Lithium-ion batteries may release multiple fluorochemicals, including PFAS such as 2,4-difluorobenzoic acid and several fluorinated electrolyte additives, under simulated landfill conditions, suggesting that end-of-life battery disposal may introduce additional PFAS sources into landfill leachate.
Lab-scale insights into the environmental fate of emerging contaminants from airport runoff
1 Dec 2025 | J Contam Hydrol.
Laboratory evidence indicates that only some contaminants in airport runoff are naturally diminished during contact with sediments, whereas PFAS remain largely persistent, raising concerns about whether soil aquifer treatment can adequately protect groundwater from these chemicals.
