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.
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.
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.
Assessment of human exposure to particle-associated organic pollutants in home environments of Lisbon, Portugal
19 Jan 2026 | Environ Res
Particle-bound PFAS including PFBS, PFHxA, PFOA, and PFNA were detected at higher concentrations indoors than outdoors in Lisbon homes, suggesting indoor materials and consumer products may be associated with ongoing PFAS inhalation exposure.
Air emissions during destruction of PFAS-containing materials
15 Jan 2026 | Nature Reviews Earth & Environment
PFAS destruction technologies may still release airborne fluorinated byproducts during treatment, suggesting that commonly used efficiency metrics alone may underestimate environmental and health risks.
Occurrence and sources of organic contaminants of emerging concern in indoor dust: A global perspective
14 Jan 2026 | J Hazard Mater
A global review finds PFAS commonly in indoor dust from homes, offices, and schools, particularly in North America, Europe, and East Asia, and identifies PFOS and PFOA as persistent legacy compounds alongside increasingly reported short-chain PFAS and precursors, suggesting ongoing indoor exposure despite regulation.
Challenges and Opportunities in PFAS Waste Management for Semiconductor Manufacturing
13 Jan 2026 | Environ Sci Technol
PFAS are widely used in semiconductor manufacturing and may be difficult to manage, highlighting the scientific and policy importance of developing industry-specific monitoring and treatment approaches because existing methods may not adequately address the diversity of PFAS as regulations tighten.
Residential proximity to transport facilities as urban determinants of individual-level per- and poly-fluoroalkyl substance (PFAS) exposures: Analysis of two longitudinal cohorts in Singapore
9 Jan 2026 | Environ Health
A longitudinal study of pregnant women in Singapore reports that residential proximity to large transport facilities, especially bus depots, is associated with higher blood levels of specific PFAS, notably PFBS, PFBA, and PFNA, highlighting a potentially important but largely unregulated urban exposure source linked to the widespread use of PFAS in automotive lubricants, hydraulic fluids, coatings, and other vehicle components.
Bioaccumulation of PFOS Isomers in Transporter Proteins
8 Jan 2026 | Chem Res Toxicol
Structural differences among PFOS isomers are associated with differing interactions with fatty acid transporter proteins, with some branched isomers potentially exhibiting comparable or greater bioaccumulation potential than linear PFOS based on combined in vitro uptake and molecular modeling results.
An integrated in vitro and in silico testing strategy applied to PFAS inhibition of antibody production to define a tolerable daily intake
3 Jan 2026 | Toxicol Lett
PFOS, PFOA, PFNA, and PFHxS, may inhibit antibody production, with modeled human-equivalent effect doses that are similar to or lower than existing European Food Safety Authority health-based guidance values.
Fate, bioaccumulation, and toxic responses of PFOA, PFOS, and GenX in the paddy soil-rice system across the full growth cycle
1 Jan 2026 | J Hazard Mater
Analysis of a full growth cycle study in paddy soil suggests that PFOA, PFOS, and the replacement PFAS GenX may disrupt rice growth and induce oxidative stress. GenX is showing greater upward movement into edible tissues, highlighting potential food-chain relevance and informing proposed soil safety thresholds for rice cultivation.
Unforeseen risks due to the use of fluorinated materials for per-and polyfluoroalkyl substance removal
30 Dec 2025 | Nature
Researchers report that fluorinated materials used for PFAS removal may inadvertently release additional fluorinated compounds during production, use, or disposal, suggesting that non-fluorinated alternatives offer safer options for treatment technologies.
