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.

Landfill Gas: A Major Pathway for Neutral Per- and Polyfluoroalkyl Substance (PFAS) Release
Science
26 Jun 2024 | ES&T L
A study of three landfills found that the mass of fluorine leaving as gas (32–76%) was comparable to the mass leaving as leachate (24–68%). FTOHs were the dominant (87–97%) total neutral PFAS constituents.
