Distribution and concentration of airborne per-and polyfluoroalkyl substances (PFAS) in indoor and outdoor environments: A systematic review
1 Apr 2026 | Saf Health Work
Airborne PFAS, including fluorotelomer alcohols, perfluoroalkyl carboxylic acids, and perfluoroalkyl sulfonic acids, are found at higher levels indoors and in occupational settings than outdoors.
Impact of regulatory actions to establish maximum contaminant levels on per-and polyfluoroalkyl substances in New Jersey public water systems
30 Mar 2026 | Environ. Int.
State-level actions to establish drinking water limits for PFOA, PFOS, and PFNA were associated with substantial reductions in contamination levels in New Jersey public water systems, suggesting such regulatory approaches may effectively reduce exposure.
Per-and polyfluoroalkyl substances leaching from micro-and nanoplastics and the associated influence of the plastisphere
29 Mar 2026 | Environ Sci Technol
Micro- and nanoplastics, particularly fluoropolymers, may release specific PFAS such as short-chain perfluoroalkyl carboxylic acids (e.g., PFBA, PFPeA, PFHxA, PFHpA) and PFOA into seawater.
Association of per-and polyfluoroalkyl substances (PFAS) exposure with cognitive function in firefighters
25 Mar 2026 | Nature
PFAS, particularly PFOS, may be associated with reduced cognitive processing speed in firefighters based on standardized cognitive testing and statistical modeling of exposure–performance relationships, indicating potential occupational health concerns and the need for exposure reduction.
Per-and polyfluoroalkyl substances (PFAS) in aquaculture feeds and potential dietary exposure to and from aquaculture fish
23 Mar 2026 | Food Chem. Toxicol.
PFAS were detected in multiple commercial aquaculture feeds, with PFOS most consistently present, and feeding trials suggesting contaminated feed may contribute to PFAS accumulation in farmed fish tissues presenting an exposure pathway for frequency seafood consumers.
Early-life exposure to per-and polyfluoroalkyl substances and heavy metals and lower lung function in school-age children: A prospective cohort study
23 Mar 2026 | Environmental Research
Early-life exposure to PFOA, PFOS, PFHxS, PFDA, and PFUnDA, measured in children’s blood alongside metals such as cadmium and mercury, was associated with reduced lung function at school age.
Recent advances and perspectives in UL‐94 V‐0 rated flame‐retardant polycarbonate: Addressing challenges under per‐and polyfluoroalkyl substances bans
23 Mar 2026 | Saf. Sci. & Tech.
Restrictions on PFAS and other halogenated flame retardants in materials such as polycarbonate plastics have led to the development of alternative flame retardants such as phosphorus–nitrogen, siloxane, sulfonate, and nano-based systems.
Fluorinated pesticides are a growing source of PFAS contamination in the environment: An Australian perspective on use, fate and ecotoxicity
23 Mar 2026 | Ecotoxicol Environ Saf
Widespread use of fluorinated pesticides, such as fipronil, trifluralin, bifenthrin, fluazinam, and flonicamid, leads to persistent environmental accumulation and transformation into mobile PFAS byproducts like trifluoroacetic acid, perfluoropropionic acid, and perfluorobutanesulfonate.
Contamination of two drinking water catchments more than 24 years after PFAS foam used to suppress highway fuel tanker fires
22 Mar 2026 | Water
PFOS and PFHxS from aqueous film-forming foams, was found to persist in drinking water catchments and sediments for more than 24 and 33 years after single tanker fire incidents at concentrations that exceeded Australian drinking water guidelines, indicating that without proper remediation measures PFAS will continue to pose a potential risks to human health.
Atmospheric transport and deposition of PFAS in East Antarctica: Evidence from snow transect measurements and a multidecadal record
20 Mar 2026 | Science Advances
PFOA, PFNA, TFA, PFPrA, and HFPO-DA were found to persist in Antarctic snow due to long-range atmospheric transport and ongoing formation from precursor chemicals.
Per-and polyfluoroalkyl substances and adolescent bone mineral density: Assessing periods of susceptibility
17 Mar 2026 | J Endocr Soc.
Higher serum concentrations of PFOA, PFOS, PFHxS, and PFNA during childhood were associated with changes in adolescent bone mineral density, with consistent links between PFOA exposure and lower density in cortical bone.
Contamination profiles of legacy and emerging per-and polyfluoroalkyl substances in various vegetable oils collected in Chinese markets
17 Mar 2026 | J. Environ. Sci.
Several common vegetable oils sold in Chinese markets, including soybean, rapeseed, sesame, sunflower, peanut, flaxseed, rice bran, corn germ, camellia, tea seed, and blended oils, were found to contain legacy PFAS such as PFOA and PFOS and emerging compounds including 6:2 FTS and GenX, with contamination patterns suggesting links to refining processes, packaging, or contaminated crops.
Species-specific profiles and implications of per-and polyfluoroalkyl substances contamination in edible insects
16 Mar 2026 | Food Control
Analysis of commercially available edible insect products derived from crickets, locusts, and mealworms found multiple PFAS, including legacy compounds such as PFOA and PFOS and replacement chemicals like GenX, with species-specific accumulation patterns that suggest insect-based foods may act as a pathway for PFAS exposure.
Perfluoroalkyl compound levels in breast milk of mothers in Riyadh, Kingdom of Saudi Arabia
