Bioaccumulation and transfer of legacy and emerging per-and polyfluoroalkyl substances throughout the lifecycle of a tropical amphibian species Fejervarya limnocharis
Science
21 Feb 2025 | Environ. Sci. Technol.
PFAS were detected throughout the lifecycle of the tropical frogs Fejervarya limnocharis, with high concentrations in eggs that decreased in tadpoles and remained stable in juvenile and adult frogs, while specific PFAS with low tendency to bind to proteins showed greater accumulation in tadpoles, suggesting different bioaccumulation patterns influenced by developmental stage and exposure pathways.

Minimizing the use of per-and polyfluoroalkyl substances for textured wetting-resistant surfaces.
Science
17 Feb 2025 | Environ. Sci. Technol.
Textured surfaces made with materials, like polydimethylsiloxane and springtail-inspired structures, were found to have water- and oil-repellent properties similar to those of PFAS, offering alternatives for applications like water purification and self-cleaning textiles.

The stubborn “chemical invader”: Challenges and solutions for per-and polyfluoroalkyl substances (PFAS) in Chinese sewage sludge
Science
17 Feb 2025 | ACS EST Water
Sewage sludge in China acts as both a source and sink for PFAS, with compounds like PFOS accumulating due to limited degradation by conventional wastewater treatments, highlighting the need for innovative extraction, detection, and environmentally sustainable removal methods to reduce associated environmental contamination and health risks.

Surface soil PFAS mixtures dominated by PFOS: Prioritization for ecotoxicity testing and ecological risk assessment at current and former US Air Force Bases
Science
7 Feb 2025 | Environ Toxicol Chem
PFAS mixtures in soil were dominated by PFOS (approximately 82%) but also included 5% to 12% of PFHxS, PFOA, PFOSA, and PFHxA. Additionally the study identified high concentrations but inconsistent prevalence of the 6:2 and 8:2 fluorotelomer sulfonates. These results highlight the need for toxicity testing of mixtures dominated by PFOS but including combinations of other PFAS.
