From carboxylates to chlorinated sulfonates: Contrasting fate and treatment prospects of GenX and F53B in WWTPs
13 Oct 2025 | Science of The Total Environment
In wastewater systems, GenX was found to largely persist in the aqueous phase with minimal degradation, while F-53B partitions to sludge and undergoes limited breakdown, and advanced treatments like UV with sulfite or electrochemical oxidation outperform conventional processes, though byproducts and limited field data remain concerns.
A review of the key impacts of deforestation and wildfires on water resources with regard to the production of drinking water.
12 Oct 2025 | Hydrology
Deforestation and especially wildfires can release pollutants into water, but wildfires pose an added threat because firefighting foams and burn residues introduce PFAS that contaminate both surface water and groundwater, making drinking water treatment far more difficult and costly.
Per- and polyfluoroalkyl substances exposure in hexavalent chromium exposed workers and the effects of exposure mixtures on oxidative stress and genomic instability
12 Oct 2025 | Environ Pollut
Workers in chrome-plating and similar industries are exposed to toxic hexavalent chromium alongside very high levels of PFAS such as PFOS and PFDA, and this combined exposure is linked to early signs of oxidative stress and DNA changes that may increase the risk of cancer, mitochondrial damage, and impaired DNA repair over time.
An unwanted hitchhiker: Assessment of per-and polyfluoroalkyl substances (PFAS) in vehicle cabin air conditioner and engine filters
10 Oct 2025 | Analytical Methods
Car cabin air filters were dominated by diPAPs and long-chain PFCAs (like PFOA, PFNA, and PFDA), showing far higher PFAS levels than engine filters, which mainly contained fluorotelomer sulfonic acids and some PFCAs, indicating that vehicle interiors are a significant source of PFAS exposure.
Advancing the understanding of PFAS-induced reproductive toxicity in key model species
29 Sep 2025 | Environ Sci Process Impacts
Across model species, PFAS commonly impair reproduction, in rodents they damage ovaries and testes, disrupt sex hormones, and weaken the blood-testis barrier, in fish they reveal reduced fecundity and abnormal development under chronic, environmentally relevant, transgenerational tests, and in C. elegans they cause heritable declines in fertility and locomotion.
Short-chain PFAS predominate in large-scale lithium battery industrial parks, Eastern China: Source apportionment and downstream impact implications
25 Sep 2025 | J. Hazard. Mater.
Lithium battery industrial parks in eastern China release significant amounts of short-chain PFAS into rivers, with urban wastewater, traditional industries, and the battery industry each contributing about one-third of the pollution, leading to ecological risks, in downstream ecosystems.
Field measurement and modelling of PFAS leachability from a contaminated fire training area–whole of pad response to rainfall
24 Sep 2025 | Water Research
Concrete and asphalt at old fire training sites where firefighting foams were used continue to release PFAS into rainwater runoff at levels around 1–4 micrograms per liter, and modeling indicates this contamination could persist for centuries without active cleanup or management.
Assessment of arsenic, cadmium, lead, mercury, and per-and polyfluoroalkyl substances concentrations in human milk and infant formula in the United States: A systematic review
23 Sep 2025 | AJCN
A review of U.S. breast milk and infant formulas found that screening for harmful contaminants such as PFAS and metals are limited or outdated, while public health agencies continue to recommend breastfeeding because of its known benefits.
Per- and polyfluoroalkyl substances and the gut microbiota in infants: A scoping review
23 Sep 2025 | Environ Res
PFAS exposure in infants, often through breast milk, maternal blood, or cord blood, was linked to shifts in gut bacteria diversity and changes in metabolism.
The moderating role of vitamin E in the association between PFAS exposures and diabetes risk: Evidence from the NHANES 2017-2018
22 Sep 2025 | Metabolism Open
Analysis of U.S. NHANES 2017–2018 data showed that higher PFAS concentrations, especially PFOS and PFNA, were linked to increased diabetes risk, but vitamin E significantly moderated these effects by reducing PFAS-related elevations in blood glucose, suggesting antioxidant protection is particularly important for older adults and men.
[Factsheet] PFAS sampling activities in the US Geological Survey national networks
19 Sep 2025 | USGS
The U.S. Geological Survey is monitoring PFAS nationwide by sampling 23 rivers up to 22 times a year, collecting over 1,200 groundwater samples from wells since 2019, and measuring PFAS in rainfall at atmospheric deposition sites to track how these long-lasting chemicals move through water, air, and soil.
Early-life dietary exposure to perfluorooctanoic acid (PFOA) through milk consumption: A systematic review
17 Sep 2025 | J Appl Toxicol
A review of 69 studies (2007–2024) found a wide range of PFOA concentrations in infant formula, commercial milk, and breast milk worldwide, highlighting the urgent need for a more systematic monitoring to protect babies and young children.
PFAS in the textile industry: Sources, fate, detection, and pathways toward sustainable remediation and regulation
15 Sep 2025 | Chem. Eng. J.
Textiles act as long-term reservoirs for PFAS, continuously releasing harmful chemicals into the environment through production, use, aging, washing, and disposal, raising major health and regulatory concerns.
Unveiling the chemical safety of clothing articles, textiles and footwear with regard to the presence of carcinogenic, mutagenic, or reprotoxic substances, endocrine disruptors and skin sensitizers under EU regulatory restrictions
12 Sep 2025 | Contact Dermatitis
Analysis of 111 apparel items focused on fast-fashion and online markets, found to contain chemicals of concern including PFAS, (detected in about one-third of samples), bisphenols, phthalates, PAHs, and isothiazolinones. Nearly a quarter of items exceeded the proposed EU restrictions limits for at least one chemical.
