Volatile per- and polyfluoroalkyl substances (PFAS) and other semi-volatile organic chemicals in indoor air of fire stations: The influence of gear storage conditions
Science
13 Apr 2026 | Environ Sci Process Impacts
Sampling across 11 fire stations identified 14 PFAS and ~120 co-occurring SVOCs in indoor air, with volatile species such as 8:2 FTOH detected at high levels in enclosed gear storage areas, suggesting turnout gear may act as a source of airborne PFAS that could potentially contribute to inhalation exposure and PFOA formation.

Okinawa town finds elevated PFAS levels near Marine base in annual water survey
News
9 Apr 2026 | Stars and Stripes
Three sites near the Ryukyu Hospital showed the highest PFAS levels, including 220 parts per trillion upstream of the hospital, 200 parts per trillion downstream and 130 parts per trillion where streams merged, according to the survey results.

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.

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.

Characterization of per-and polyfluoroalkyl substances in crushed concrete from a source with known AFFF exposure: Outlooks for recycling
Science
6 Apr 2026 | JHM: Organics.
Crushed concrete from sites exposed to aqueous film-forming foams were found to contain elevated levels of PFAS, particularly PFOS and PFHxS, that persist below the surface and can make recycled material unsuitable for reuse, limiting the potential regulatory and management challenges.

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.

Association of per-and polyfluoroalkyl substances (PFAS) exposure with cognitive function in firefighters
Science
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.

Exploring per-and polyfluoroalkyl substances exposure risk in indoor air and PM2. 5: Correlations with respiratory health in university environments
Science
9 Mar 2026 | Env. Poll.
Indoor air and PM2.5 in university environments contained PFAS such as PFPeA, PFOA, PFOcDA, PFHxDA, and PFOS that were also detected in students’ exhaled breath condensate, suggesting inhalation exposure may be linked to respiratory inflammatory responses, though estimated exposure risk was low and results are based on limited observational correlations.

Characterizing per-and polyfluoroalkyl substances (PFAS) exposure in petrochemical workers: Insights from paired blood and urine samples
Science
9 Mar 2026 | Molecules
PFAS exposure in petrochemical workers is elevated relative to the general population but lower than highly exposed industries, with PFOA dominating blood burdens, PFPeA dominating urine, long-chain PFAS accumulating in blood while short-chain PFAS are preferentially excreted, and cumulative exposure primarily driven by years of occupational service.
