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.
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.
The unintentional role of chemical regulation in regrettable substitution: The case of PFAS
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.
Associations between per-and polyfluoroalkyl substances and metabolic dysfunction-associated steatotic liver disease in adolescents and young adults: Modifying roles of age, lifestyle factors, and PNPLA3 genotype
25 Nov 2025 | Environ. Res.
High quality imaging suggests that PFOA and PFHpA, and possibly PFNA and PFHxS in certain subgroups, may be linked to higher risk of adolescent fatty liver disease, with stronger patterns in older youth, smokers, and PNPLA3 carriers, highlighting potential early-life vulnerability.
Exposure to per-and polyfluoroalkyl substances (PFAS) and phthalate metabolites and their association with low estimated glomerular filtration rates in the US population
21 Nov 2025 | Food Chem Toxicol.
Evidence from NHANES data suggests that PFAS degradation product, MPAH and many phthalate metabolites may be associated with reduced kidney function in US adults, highlighting potential nephrotoxic risks that could inform chemical regulation and public health monitoring.
Regrettable for whom? GenX chemicals as a case study in detrimental chemical substitution
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
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.
Nationwide estimate of volatile per-and polyfluoroalkyl substance (PFAS) emissions from US landfills via landfill gas
17 Nov 2025 | Environ. Sci. Technol.
Landfill gas was found to contain notable levels of volatile PFAS, particularly 6:2 and 8:2 FTOH, suggesting that landfills may act as an underrecognized source of atmospheric PFAS emissions and raising policy concerns due to major uncertainties in how effectively these compounds are managed.
Perfluoroalkyl and polyfluoroalkyl substances contamination in dairy: A global perspective.
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.
Development and evaluation of analytical strategies for the monitoring of per- and polyfluoroalkyl substances from lithium-ion battery recycling materials
11 Nov 2025 | Anal Bioanal Chem
The results of this study underline the threat of PFAS emissions from lithium-ion battery waste and recycling activities. Both legacy (PFSA and PFCA) and emerging PFAS were found, with levels of TFA found in every investigated material type.
PFAS-induced immunotoxicity in freshwater fish of inland China: mechanisms and ecological risks
10 Nov 2025 | Comp. Biochem. Physiol. C
PFAS are widespread in China’s freshwater systems, where long-chain and sulfonic types result in suppressed immune responses and higher infection risk. These effects worsen with co-exposure to heavy metals and microplastics.
Associations between per- and polyfluoroalkyl substances and reproductive outcomes among women undergoing in vitro fertilization/intracytoplasmic sperm injection treatment
10 Nov 2025 | Reprod Toxicol
Mixed exposure to long-chain PFAS and emerging chlorinated PFESAs in infertile Chinese women was associated with increased risk of infertility.
