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.
A Componential Evaluation of Per- and Polyfluoroalkyl Substances (PFAS) in Municipal Solid Waste (MSW) Streams
30 Dec 2025 | Environ Sci Technol
PFAS were detected in every major waste component, with PFAS-treated textiles, which make up only about 9 percent of the waste stream, contributed roughly 38 percent of all leachable PFAS, identifying them as a dominant source of PFAS release from municipal solid waste from waste collected from Central Florida.
Per-and polyfluoroalkyl substances (PFASs) contamination and community impact: An interdisciplinary approach to teaching chemistry
29 Dec 2025 | Journal of Chemical Education
Students engaged in an interdisciplinary chemistry module were found to have an improved understanding of PFAS contamination and its ties to environmental inequity, suggesting that integrating socioscientific issues into core chemistry courses may better prepare students to navigate the ethical, cultural, and political dimensions of real world environmental challenges.
Developmental Toxicity of Photolithography-Relevant Per- and Polyfluoroalkyl Substances (PFAS) Reveals Concerns for Less-Studied Functional Groups
24 Dec 2025 | Environ Sci Technol
Several PFAS used in semiconductor manufacturing, including perfluoroalkyl dicarboxylic acids and perfluorosulfonamides, may cause developmental toxicity and disrupt lipid-metabolism genes in zebrafish at environmentally relevant levels, raising concerns for their continued use.
Serum perfluoroalkyl and polyfluoroalkyl substances and the risk of cardiometabolic diseases: Unraveling the mediating role of inflammatory markers
24 Dec 2025 | Eco Environ Health
Combined exposure to several PFAS was associated with increased risk of cardiometabolic conditions, particularly abnormal blood lipids and high blood pressure, with specific PFAS such as PFHxS, PFNA, and PFTrDA emerging as potential key contributors.
Gulls foraging in highly urbanized areas experience disruption in hormones and energetic metabolism
20 Dec 2025 | Environ Int
Urban-breeding ring-billed seagulls exposed to PFAS and halogenated flame retardants show sex-specific associations with thyroid hormones, corticosterone, and lipid metabolism markers, suggesting these chemicals may disrupt hormone regulation and energy metabolism.
Reevaluating PFAS exposure risks from marine fish
18 Dec 2025 | Science
A global modeling analysis finds that legacy PFAS exposure from marine fish may now be low for most countries due to production phaseouts, yet remains higher in places with very high seafood intake such as Greenland and Denmark, offering important insight for refining fish consumption guidance and noting where potential risk persists.
