PFAS concentrations in the blood of Danish surfers
20 Jan 2025 | Int J Hyg Environ Health
PFAS concentrations in the blood of Danish surfers were measured, revealing no significant relationship between the amount of time spent surfing and higher PFAS levels, but male sex and eating meat from free-ranging animals were found to be potential risk factors for increased exposure.
Bone cell differentiation and mineralization in wild-type and osteogenesis imperfecta zebrafish are compromised by per-and poly-fluoroalkyl substances (PFAS)
17 Jan 2025 | Sci Rep
Exposure to PFOS, PFOA, and PFHxA harmed bone development in zebrafish, disrupting bone cell growth, increasing cell death, and affecting fat storage, with more severe effects in the zebrafish with pre-existing bone issues.
Microcontaminants and microplastics in water from the textile sector: a review and a database of physicochemical properties, use in the textile process, and ecotoxicity data for detected chemicals
17 Jan 2025 | Environ Sci Process Impacts
PFAS were a large proportion of more than 500 contaminants found in wastewater treatment plants processing textile factory waste, raising concern for their ecotoxicity as the treatment plants do not effectively remove many chemicals.
Persistent pollutant exposure impacts metabolomic profiles in polar bears and ringed seals from the High Arctic and Hudson Bay, Canada
15 Jan 2025 | Environ Res
PFAS exposure in polar bears and ringed seals from the High Arctic and Hudson Bay was linked to significant alterations in their metabolomic profiles, particularly affecting lipid metabolism, bile acid synthesis, and antioxidant defenses, with ringed seals showing a greater sensitivity to these chemicals than polar bears.

PFAS contamination was found in 84% of e-cigarette refill liquids, with certain compounds detected at significant levels, raising concerns about additional health risks from vaping and PFAS environmental release.
Socioeconomic Disparities in Exposures to PFAS and Other Unregulated Industrial Drinking Water Contaminants in US Public Water Systems
15 Jan 2025 | Environ Health Perspect
Socioeconomic and racial disparities are linked to higher exposures to unregulated industrial contaminants, such as PFAS and 1,4-dioxane, in U.S. public water systems, with more than 97 million US residents being exposed to at least one of four unregulated contaminants.
Levels and oxidative toxicity of microplastics and perfluoroalkyl substances (PFASs) in different tissues of sea cucumber (Holothuria tubulosa)
13 Jan 2025 | Sci Total Environ
Sea cucumbers, as key marine organisms, serve as indicators of environmental pollution, and their exposure to microplastics and PFAS highlights the potential risks these pollutants pose to marine ecosystems and human health through the food chain.
Research on the PFAS release and migration behavior of multi-layer outdoor jacket fabrics
13 Jan 2025 | J Hazard Mater
The release and migration of PFAS from outdoor jacket fabrics, especially those treated with short-chain fluorinated polymers (C6F13-SFPs), increase during aging, abrasion, and washing cycles, posing significant environmental risks through the migration of PFAS into the environment and the release of microfibers that carry these pollutants.
