Exploring dog saliva as a non-invasive alternative to blood sampling for chemical exposome studies: analysis of synthetic phenolic antioxidants and PFAS.
Science
2 Feb 2026 | Front Vet Sci
In a pilot study of privately owned dogs, PFNA and both linear and branched PFOS were most frequently detected in saliva, while serum also contained PFOA, PFNA, PFDA, PFUnDA, PFBS, and PFHxS, indicating multi-congener PFAS exposure comparable to humans.

Model-based assessment of adsorption and diffusion of PFASs through concrete as continuous Source of PFASs to the environment
Science
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
Science
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.

High-resolution mass spectrometry analysis of legacy and emerging PFAS in oilfield environments: Occurrence, source, and toxicity assessment
Science
26 Jan 2026 | Toxics
Oilfield sites showed elevated and diverse PFAS contamination associated with displacement agents, and the PFOS substitute p-perfluorous nonenoxybenzenesulfonate appears similarly persistent and bioaccumulative while potentially linked to greater developmental cardiac toxicity than PFOS.

Evaluating Legacy and Emerging PFAS in Human Blood Collected from 2003 to 2021
Science
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
Science
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
Science
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.

Assessment of human exposure to particle-associated organic pollutants in home environments of Lisbon, Portugal
Science
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.

Bioaccumulation of PFOS Isomers in Transporter Proteins
Science
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.
