Mediating role of proteomics in the association between per-and polyfluoroalkyl substance exposure and blood pressure in youth
Science
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.

Investigating anaerobic digestion microbiome resilience to high PFOA and PFOS mixtures during cometabolism
Science
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
Science
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.

Development and validation of an LC-MS/MS method for simultaneous determination of 39 PFAS in soil samples: applications to playgrounds in Attica, Greece
Science
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.

Lab-scale insights into the environmental fate of emerging contaminants from airport runoff
Science
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.
Science
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.

Arsenic, Cadmium, Lead, Mercury, and PFAS Exposure During Pregnancy or Lactation and Respective Concentrations in Human Milk: Systematic Review
Science
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.

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

The unintentional role of chemical regulation in regrettable substitution: The case of PFAS
Science
25 Nov 2025 | ES&P
The authors argue that regulatory systems like TSCA and REACH may unintentionally drive regrettable PFAS substitutions by allowing insufficiently assessed alternatives onto the market, highlighting the policy significance of shifting toward earlier hazard evaluation, coordinated global oversight, and mechanisms to prevent substitution with equally persistent or hazardous chemicals.

‘Toxic Soup’: PFAS and other contaminants surged in French Broad River after Helene
News
24 Nov 2025 | NC Health News
Among the chemicals detected were 11 types of PFAS, including PFOA and PFOS, which the study found at levels exceeding the Environmental Protection Agency’s maximum contaminant levels of 4 parts per trillion.

Regrettable for whom? GenX chemicals as a case study in detrimental chemical substitution
Science
18 Nov 2025 | Environ. Sci. Policy
The example of GenX’s substitution for PFOA shows how structural factors in the US chemical regulatory system, including data gaps, permissive loopholes, and limited oversight, can enable detrimental chemical replacement. These findings underscore the need for stronger policies that prioritize public health.

Asymmetrical contamination of anionic PFAS across global freshwater reservoirs
Science
18 Nov 2025 | Water Research
Freshwater reservoirs across Asia, North America, Europe, Africa, and Oceania show three distinct PFAS contamination stages, including PFOA-dominated, PFOA plus PFOS co-dominated, and short-chain PFBA-dominated profiles, which together point to the need for more coordinated global multi-media PFAS monitoring and governance.

Perfluoroalkyl and polyfluoroalkyl substances contamination in dairy: A global perspective.
Science
17 Nov 2025 | Sci Total Environ
PFOS, PFOA, and other PFAS may contaminate milk and dairy products through polluted water, PFAS-treated feed, food-contact packaging, and fluoropolymer-coated equipment, raising concern for infant and population-wide exposure and underscoring the need for stronger global monitoring and regulatory alignment given highly variable and sometimes inconsistent contamination data.

Concentrations of per- and polyfluoroalkyl substances in Canadian sea otters (Enhydra lutris) are higher near urban centers
Science
4 Nov 2025 | Environ Toxicol Chem
PFAS were detected in all sampled British Columbia sea otters, with liver concentrations over 25 times higher than in muscle tissue and dominated by PFNA, PFOSA, and PFOS.

Childhood exposure to per-and polyfluoroalkyl substances during eating activities: Occurrence, exposure, and developmental risk
Science
3 Nov 2025 | J. Environ. Chem. Ecotoxicol.
Children’s feeding bibs and tablecloths were found to contain multiple PFAS, including PFOA, PFNA, and PFOS. Modeled hand-to-mouth exposure during meals was estimated to approach or exceed safety thresholds for infants that potentially disrupt hormone and developmental pathways.
