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.

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.

Associations between PFAS in public water system drinking water and serum among Southern California adults
Science
30 Oct 2025 | J Expo Sci Environ Epidemiol
PFAS contamination in drinking water may be a significant contributor to adult serum PFAS levels, even among communities without high level contamination from industrial manufacturing.

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in seafood from Thailand: Levels, geographic distribution, and risk from dietary exposure
Science
27 Oct 2025 | Environ Monit Assess
Short-chain PFAS like PFBS and PFPeA were the most common contaminants found in Thai rivers and irrigation canals, showing that industrial discharge, agriculture, and urban runoff are spreading these persistent chemicals even into areas once considered clean.

Association between maternal exposure to per-and polyfluoroalkyl substances and childhood growth trajectories up to 4 years of age: The Japan environment and children’s study
Science
24 Oct 2025 | Environ Sci Technol
Maternal exposure to PFAS during pregnancy was linked to slower early childhood growth in Japan, with higher PFOS, PFOA, and PFHxS levels associated with lower weight gain and shorter height through age four, suggesting that prenatal PFAS exposure may hinder fetal and postnatal development.

Challenging assumptions: Per-and polyfluoroalkyl substances detected in deep groundwater across southeastern Australia
Science
22 Oct 2025 | ACS ES&T Water
PFAS compounds were detected in deep groundwater across southeastern Australia, including aquifers over 100 meters deep, revealing that even supposedly protected water sources are vulnerable to contamination through surface infiltration, bore leakage, and long-range subsurface transport.

Concentrations of per-and polyfluoroalkyl substances (PFAS) in private well drinking water and serum of individuals exposed to PFAS through biosolids: The Maine Biosolids Study
Science
20 Oct 2025 | Environ. Pollut.
Individuals living near farmland where PFAS-contaminated biosolids were historically applied had elevated PFAS in their private well water and blood, especially PFOA, which showed a strong water-to-serum correlation, demonstrating that biosolids can be a major exposure source and that some people may still have high serum levels even when their current water meets standards.
