Quantitative Associations of Per- and Polyfluoroalkyl Substances in Segmented Hair with Serum and Dust: Potential of Hair as a Retrospective Biomarker
Science
23 Feb 2026 | Environ Sci Technol
In a two-year panel of female e-waste workers, concentrations of long-chain perfluorosulfonic acids in segmented hair were positively associated with corresponding average serum levels over matched prior months, suggesting hair may retrospectively reflect internal exposure, while short-chain PFAS showed weaker or inconsistent relationships.

Fish-based pet food may expose cats and dogs to forever chemicals
News
20 Feb 2026 | New Scientist
A survey of 100 commercial foods for dogs and cats revealed that PFAS chemicals appear in numerous brands and types, with fish-based products among those with the highest levels.

Open dumps as a critical source of per-and polyfluoroalkyl substances in agricultural soils of Pakistan: Evidence of trifluoroacetic acid dominance
Science
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.

Tracking PFAS across environmental media surrounding fluorochemical industrial park: Insights from nontarget analysis and risk assessment
Science
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.

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
Science
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.

Longitudinal PFAS exposure and thyroid function trajectories in Taiwanese youth: a 10-year prospective cohort study
Science
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.

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.

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
Science
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.

Childhood exposure to per-and polyfluoroalkyl substances in educational environments: Arising from stationery and implications for health
Science
15 Dec 2025 | J. Environ. Chem. Ecotoxicol.
Several products purchased in China released measurable PFAS including precursors that increased after oxidation and maximum estimated intake from hand to mouth contact with some pen grips approaching the European Food Safety Authority tolerable intake for children.

Nationwide occurrence and flux estimates of PFAS in leachate from waste-to-energy sector: An emerging reservoir linked to short-term waste storage
Science
25 Nov 2025 | Water Res
Chinese municipal solid waste incinerators leachates may act as a concentrated source of short-chain PFAS, particularly PFBA and PFBS, although membrane treatment removes most PFAS, the persistence or even increase of compounds like GenX suggests potential limitations that are important for environmental monitoring and policy decisions.

PFAS-induced immunotoxicity in freshwater fish of inland China: mechanisms and ecological risks
Science
10 Nov 2025 | Comp. Biochem. Physiol. C
PFAS are widespread in China’s freshwater systems, where long-chain and sulfonic types result in suppressed immune responses and higher infection risk. These effects worsen with co-exposure to heavy metals and microplastics.
