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.

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.

Nationwide occurrence and flux estimates of PFAS in leachate from waste-to-energy sector: An emerging reservoir linked to short-term waste storage

25 Nov 2025 | Water Res

Chinese municipal solid waste incinerators leachates may act as a concentrated source of short-chain PFAS, particularly PFBA and PFBS, although membrane treatment removes most PFAS, the persistence or even increase of compounds like GenX suggests potential limitations that are important for environmental monitoring and policy decisions.

Bone marrow accumulation of perfluoroalkyl substances (PFASs) predicts post-transplant relapse in acute myeloid leukemia patients and associated with T-cell dysregulation

25 Nov 2025 | Ecotoxicol Environ Saf

Higher early post-transplant levels of PFOA, PFOS, 9Cl-PF3ONS, and PFUnDA in the bone marrow of leukemia patients were linked to patterns of T-cell disruption associated with relapse, pointing to a potential environmental influence on immune recovery after a transplant.
