Unveiling the toxic mechanism of nanoscale tire wear particles to algae: The interplay of particle size, photoaging, and co-existing PFOS
20 Feb 2026 | Water Res
PFOS may amplify the toxicity of tire wear particles in freshwater algae, particularly after nanoscale particles undergo photoaging, which may enhance PFOS bioaccumulation and contribute to oxidative and metabolic stress.
Ionic PFAS in PM2. 5 and dust: Insights on indoor-outdoor profiles and distribution
16 Feb 2026 | Environ. Pollut.
Ionic PFAS were detected widely in indoor and outdoor PM2.5 and dust in Calgary, Canada with findings suggesting long-chain PFCAs may originate from shared indoor sources and partition between air and dust, potentially contributing to inhalation exposure, while short-chain PFCAs may increase during wildfire events and facilitate long-range transport.
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.
Open dumps as a critical source of per-and polyfluoroalkyl substances in agricultural soils of Pakistan: Evidence of trifluoroacetic acid dominance
14 Feb 2026 | Environ Pollut
Open dumps may function as long-term reservoirs of PFAS in nearby agricultural soils, with short-chain compounds such as trifluoroacetic acid dominating contamination and urban areas showing higher burdens.
HFPO-TA provokes greater gill injury than PFOA in Opsariichthys bidens: A toxicological assessment of a next-generation PFAS substitute
14 Feb 2026 | Environ Int
In a controlled fish study, the PFAS substitute HFPO-TA was associated with greater disruption of gill structure, antioxidant defenses, immune signaling, and mitochondrial regulation than PFOA, suggesting it may pose heightened ecological risk despite its use as a replacement.
Impact of Perfluorinated Organic Acids on Bacterial Ice Nucleators
10 Feb 2026 | J Phys Chem B
In a lab study, PFOA and PFOS were found to interfere with bacteria that help initiate ice formation, which could potentially affect how freezing occurs in weather and ecological systems.
PFAS Contamination in Florida Estuarine Fishes: Levels, Patterns, and Estimated Human and Ecological Health Risks
9 Feb 2026 | Environ Res
PFAS were detected across multiple estuarine fish species along Florida’s Atlantic coast, with PFOS often dominating tissue burdens and concentrations in some species potentially exceeding ecological benchmarks such as the EU biota standard and Canadian wildlife dietary guidelines, as well as human exposure thresholds including the EPA PFOS reference dose.
Tracking PFAS across environmental media surrounding fluorochemical industrial park: Insights from nontarget analysis and risk assessment
7 Feb 2026 | Environ. Sci. Technol.
A fluorochemical industrial park in Zhejiang, China identified 112 PFAS across water, sediment, and soil, many of them emerging compounds that may pose ecological and human health risks comparable to or greater than legacy substances, suggesting emissions could contribute to complex and undercharacterized contamination profiles not fully addressed by current monitoring frameworks.
Sustainable PFAS removal from electronics wastewater through a cost-health trade-off framework
6 Feb 2026 | Environ. Sci. Technol.
Upstream treatment of PFAS in electronics and semiconductor wastewater could substantially reduce projected human toxicity at costs that appear modest relative to industry market value, although trade-offs vary by region and removal stringency as manufacturing growth may drive increasing releases.
Association of PFAS, metals, phthalate and organophosphate metabolites with depression among US adults
6 Feb 2026 | Int. J. Environ. Res. Public Health
Using NHANES 2017–2018 data, certain organophosphate and phthalate metabolites were associated with higher depressive symptom scores, with mixture modeling suggesting organophosphates may contribute most strongly to the overall signal, while PFAS and heavy metals showed similar linear associations.
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
