Microplastics as vectors of antibiotics, heavy metals, and PFAS from agricultural soils to the food chain: Sources, transport pathways, and human health implications
15 Feb 2026 | J. Hazard. Mater.
PFAS adsorption was generally highest on PET and in polypropylene, indicating that certain widely used polymers may preferentially accumulate PFAS and potentially enhance their transport within agricultural and food systems.
Profile distribution and health risk assessment of per-and polyfluoroalkyl substances in indoor dust from urban households in Uganda, East Africa
3 Feb 2026 | Emerging Contaminants
A mixture of legacy and emerging PFAS was detected in indoor dust, most commonly fluorotelomer alcohols like 10:2 FTOH and 6:2 FOTH, sulfonamide N-EtFOSE, and ionic PFAS, likely originating from consumer products such as food packaging, semiconductors, and textiles.
Atmospheric deposition and co-occurrence patterns of organophosphate flame retardants (OPFRs) and perfluorooctanoic acid (PFOA) in urban snow
3 Feb 2026 | J AOAC Int.
Fresh snow in urban Romania was found to act as a temporary sink for multiple airborne pollutants, such as chlorinated organophosphate flame retardants and PFOA, with potential atmospheric deposition as a pathway for downstream exposure during snowmelt.
Validation of the U.S. Food and Drug Administration's Method for Detection of Per- and Polyfluoroalkyl Substances Analytes in Food and Feed: First Action 2025.06
3 Feb 2026 | J AOAC Int
The U.S. FDA method was found to reliably measure 30 PFAS, such as PFOS, PFOA, PFNA, and PFHxS, across a range of human and animal foods.
Temporal Trends of Per- and Polyfluoroalkyl Substances (PFASs) in Tibetan Plateau Sediment Cores (1952-2020): Tracking Global Emission History and Industrial Transformation in PFAS Production
3 Feb 2026 | Environ Sci Technol
Sediment records from remote Tibetan Plateau lakes indicate PFAS deposition has increased over time and shifted toward short-chain compounds after 2000, likely reflecting global regulation-driven changes.
Assessment of per-and poly-fluoroalkyl substances (PFAS) and polybrominated diphenyl ethers (PBDEs) in surface waters used for urban water supply in Brazil
2 Feb 2026 | Toxics
PFAS and PBDEs were consistently detected in surface waters supplying urban populations in southeastern Brazil, with seasonal patterns suggesting links to urban and industrial influences and highlighting potential drinking water concerns in a country without specific regulatory limits.
PFAS in commercially available organic amendments and food-contact paper products
1 Feb 2026 | Sci Total Environ
PFHxA and other short-chain PFCAs are dominant in composts and food-contact paper products, with PFOS dominant in biosolid-derived fertilizers, suggesting different waste sources may introduce distinct PFAS mixtures into soils used for gardening and agriculture.
Model-based assessment of adsorption and diffusion of PFASs through concrete as continuous Source of PFASs to the environment
28 Jan 2026 | ACS EST Engg.
Modeling of long-term laboratory data suggests PFAS may slowly diffuse into and back out of concrete, making paved surfaces a potentially persistent secondary source to surface runoff even after active releases stop.
PFAS in the buzz: Seasonal biomonitoring with honey bees (apis mellifera) and bee-collected pollen
26 Jan 2026 | Environ. Pollut.
PFAS destruction efforts must be evaluated not only for their effectiveness and efficiency to address commonly used PFAS but also on whether in the process they release other PFAS byproducts.
Longitudinal PFAS exposure and thyroid function trajectories in Taiwanese youth: a 10-year prospective cohort study
26 Jan 2026 | Environ Int
Long-term PFAS exposure in adolescents and young adults was associated with persistently lower thyroid-stimulating hormone and modestly higher free thyroxine over a decade, suggesting PFAS may disrupt hormonal regulation during a sensitive developmental window, with potential implications for long-term health.
Comprehensive assessment of poly-and perfluoroalkyl substances in China: Flows, stocks, and emissions from polytetrafluoroethylene
24 Jan 2026 | Environ Sci Technol
Life-cycle analysis found that nonpolymeric PFAS associated with PTFE production in China may be a dominant source of environmental release and are increasingly shifting from legacy compounds toward emerging alternatives, highlighting production stage controls as possible regulatory leverage points.
Evaluating Legacy and Emerging PFAS in Human Blood Collected from 2003 to 2021
21 Jan 2026 | Environ Sci Technol
Analysis of U.S. blood samples suggests that although phased-out PFAS such as PFOS and PFOA have declined, replacement PFAS including 9Cl-PF3ONS, 6:2 DiPAP, and related phosphonate and phosphate compounds are increasingly detected, raising concerns since their sources, toxicity, and long-term health relevance remain poorly understood.
Whales contribute to novel insight on poly-and perfluoroalkyl substances bioaccumulation in the East China Sea
19 Jan 2026 | Environ. Pollut.
PFAS including long-chain perfluoroalkyl carboxylates and the PFOS substitute 6:2 Cl-PFESA were widely detected across multiple whale species and tissues from the East China Sea, with species- and tissue-specific accumulation patterns suggesting that PFAS exposure and bioaccumulation may be underestimated or biased when marine monitoring relies on a single bioindicator species.
The occurrence, sources, and health risks of per-and polyfluoroalkyl substances (PFAS) in pm 2. 5 in Shihezi, a typical inland arid industrial city
19 Jan 2026 | Atmos. Pollut. Res.
PFAS were widely detected in fine particulate air pollution in an arid industrial city, dominated by short chain compounds linked to industrial emissions and atmospheric transformation, suggesting that airborne PFAS exposure may be underestimated when total human exposure, particularly for children.
Surface energy and pinning forces of fluorine-free, water-friendly coatings for medical devices
19 Jan 2026 | Langmuir
PFAS-free plasma and acid surface treatments may provide medical device coatings with wettability and friction performance similar to fluorinated coatings, indicating a potential pathway to reduce reliance on persistent PFAS while meeting functional requirements.
