Prenatal exposure to per- and polyfluoroalkyl substances (PFAS) and incidence of asthma and wheeze in childhood: A register-based cohort study in Ronneby, Sweden
Science
9 Apr 2026 | PLoS Med
PFAS, including PFOS, PFHxS, and PFOA from AFFF-contaminated drinking water, was associated with increased childhood asthma incidence, while no associations were observed at lower exposure levels, suggesting a possible threshold effect.

Traditional fermentation amplifies PFAS bioaccessibility: Defining fermented fish products as an unrecognized source of dietary exposure
Science
8 Apr 2026 | Environ Sci Technol
Traditional fermentation of fish products may substantially increase the bioaccessibility, and thus potential dietary exposure, of PFAS such as PFOS and PFOA by breaking down proteins and fats during fermentation, which frees PFAS that were previously trapped in the food structure.

Global inventory of fluoropolymer production plants and their associated PFAS environmental contamination
Science
8 Apr 2026 | Environ Sci Technol
A global assessment of industrial sites manufacturing fluorinated polymers indicates that releases of perfluoroalkyl carboxylic acids, perfluoroalkyl sulfonic acids, and ether-based alternatives are commonly detected in air, water, soil, and biota, often at elevated levels and across broad distances.

Associations of serum PFAS with COVID-19 antibody levels among fully vaccinated adults
Science
6 Apr 2026 | Environ. Res.
Higher serum PFAS levels were associated with lower COVID-19 antibody responses in vaccinated adults in a community with historic PFAS drinking water contamination, reinforcing the importance of reducing human exposure through effective policy measures such as establishing and enforcing strong drinking water standards.

Invasive Burmese pythons (Python bivittatus) as sentinels for PFAS biomonitoring in the Greater Everglades Ecosystem.
Science
6 Apr 2026 | Sci Total Environ
PFAS, particularly PFOS along with long-chain PFCAs such as PFOA, PFNA, and PFDA, were widely detected and bioaccumulated in Burmese pythons from the Everglades, suggesting these apex predators may reflect ecosystem-level contamination and exposure risks.

Migration of per‐and polyfluoroalkyl substances in soil under rainfall simulation
Science
3 Apr 2026 | PLoS Med
Rainfall simulation experiments suggest that PFAS such as PFOS, PFOA, and PFHxS, may migrate primarily through leaching with additional transport via runoff, with wetting-dry cycles potentially redistributing PFAS to surface soils and enhancing mobilization.

Chemical exposome patterns in mothers and children across urbanisation levels in five European birth cohorts
Science
2 Apr 2026 | J Expo Sci Environ Epidemiol
Urban versus non-urban living may shape exposure to multiple chemicals during pregnancy and childhood, with some substances like phenols and phthalates higher in urban areas while PFAS associated with agricultural practices such as PFOA, PFOS, PFNA, PFHxS, and PFUnDA may be higher in non-urban children.

Per-and poly-fluoroalkyl substances in lung tissues and their association with lung cancer.
Science
1 Apr 2026 | J. Hazard. Mater.
PFOS, PFOA, PFCAs, and PFSAs, were detected in lung tumor tissues from cancer patients and were associated with cancer biomarkers, suggesting that these chemicals may accumulate in lungs and could be linked to disease processes.

Impact of regulatory actions to establish maximum contaminant levels on per-and polyfluoroalkyl substances in New Jersey public water systems
Science
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
Science
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.

Early-life exposure to per-and polyfluoroalkyl substances and heavy metals and lower lung function in school-age children: A prospective cohort study
Science
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.

Atmospheric transport and deposition of PFAS in East Antarctica: Evidence from snow transect measurements and a multidecadal record
Science
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
Science
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
Science
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
Science
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.
