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.
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.
Assessing PFAS exposure in Rocky Mountain elk (Cervus canadensis nelsoni) populations adjacent to the former Rocky Flats nuclear site: A preliminary analysis.
1 Dec 2025 | PLoS One
Preliminary analysis finds that PFOS was consistently detected in elk livers at both Rocky Flats and control sites while PFOA was not detected, suggesting that PFOS may accumulate in elk regardless of proximity to known contamination sources and highlighting potential wildlife exposure pathways and implications for game consumption.
Could the Risk of Chronic Degenerative Valve Disease (CDVD) in Dogs Depend on Exposure to Endocrine-Disrupting Chemicals Polluting the Environment?
28 Nov 2025 | Animals (Basel)
A small-scale study found that several endocrine disrupting chemicals, including PFAS such as PFHpA and PFOA as well as parabens and BPA, were found at higher levels in dogs with CDVD, a pattern that could have implications for monitoring environmental contributors to cardiac disease.
Non-destructive surface sampling of PFAS exposure on firefighter protective gears: Potential implications for occupational exposure
27 Nov 2025 | J. Hazard. Mater.
Firefighter turnout gear and self-contained breathing apparatus surfaces may contain notable levels of PFAS, particularly 6:2 FTS, indicating potential occupational exposure through skin contact and inhalation underscoring a need for improved monitoring while noting that minor PFAS signals in blanks may introduce some uncertainty.
Arsenic, Cadmium, Lead, Mercury, and PFAS Exposure During Pregnancy or Lactation and Respective Concentrations in Human Milk: Systematic Review
26 Nov 2025 | Environ Res
Evidence from 46 studies suggests that higher maternal exposure to lead, mercury, PFOA, and PFOS may be linked with higher concentrations of the same contaminants in human milk, potentially exposing infants during critical development windows.
