National Assessment of PFAS in Landfill Leachate in China: Non-Negligible Ultrashort-Chain Components and Socioeconomic Impacts
Science
20 May 2025 | Environ Sci Technol
A nationwide survey of 70 Chinese landfills found that their wastewater holds sizable amounts of PFAS, mostly newer ultrashort‑chain chemicals, releasing about 419 kg into the environment each year and underscoring the need for stricter waste controls.

A comprehensive analytical approach to monitoring selected emerging contaminant classes in sewage sludge and e-waste from Norway
Science
19 May 2025 | J. Environ. Chem. Ecotoxicol.
Norwegian researchers found that anaerobic digestion of sewage sludge converts PFAS precursors into highly mobile perfluorocarboxylic acids and leaves more persistent long‑chain PFAS, while discarded e‑waste plastics, although less contaminated, still harbor up to 176 ng g⁻¹ of PFAS, indicating that both sludge treatment and electronics recycling inadvertently leak these pollutants.

Evaluating the hypothesis of per-and polyfluoroalkyl substances (PFAS) presence in HDPE geomembranes
Science
22 Apr 2025 | J. Hazard. Mater. Adv.
Ultra-short-chain PFAS (specifically PFPrA) were detected in all tested HDPE geomembranes used for waste containment—potentially leading to elevated PFAS concentrations in landfill leachate.

Elevated PFAS precursors in septage and residential pump stations
Science
25 Mar 2025 | Environ. Sci. Technol. Lett.
Septic systems and residential pump stations—despite lacking industrial input—were found to be significant sources of PFAS contamination, with septic systems showing especially high levels of PFAS precursors like diPAPs, underscoring the need to include precursor analysis in monitoring and to strengthen wastewater treatment strategies for decentralized systems.

Leaching profile of per-and polyfluoroalkyl substances from selected e-waste components and potential exposure pathways from discarded components
Science
17 Mar 2025 | J Hazard Mater
Discarded electronics like cables, keyboards, monitors, and circuit boards can release harmful PFAS—especially PFBA, PFHxA, PFOA, and PFOS—into the environment through leaching, highlighting e-waste as a significant but underrecognized source of long-term contamination and exposure risks.

A Pilot Study of Bis-perfluoroalkyl Sulfonimides in Dust from E-waste and Urban Regions
Science
12 Nov 2024 | Environ. Sci. Technol. Lett.
Dust samples from e-waste recycling sites showed significantly higher levels of bis-FMeSI (median 12 ng/g) compared to surrounding and urban areas, indicating e-waste recycling as a major source of environmental release for this emerging PFAS, which poses potential ecological and human health risks.

Permeation of Per-and Polyfluoroalkyl Substances (PFAS)-Laden Leachate in Landfills as an Outcome of Puncture Failures of High-Density Polyethylene Geomembranes
Science
12 Nov 2024 | Environmental Pollution
Puncture failures in high-density polyethylene landfill liners increase the permeation of hazardous PFAS-laden leachate. Short-chain PFAS, due to their surfactant properties, significantly enhanced permeation rates, highlighting concerns over environmental contamination if proper landfill protections are not maintained.

Identification of Emerging Per-and Polyfluoroalkyl Substances (PFAS) in E-waste Recycling Practices and New Precursors for Trifluoroacetic Acid
Science
23 Aug 2024 | Environ. Sci. Technol.
Soil samples from e-waste recycling sites in Pakistan revealed significant PFAS contamination, dominated by trifluoroacetic acid (TFA) and 6:2 fluorotelomer sulfonic acid, with concentrations up to 367 ng/g, indicating substantial environmental impact from these hazardous recycling practices.
