Per- and Polyfluoroalkyl Substances in Food Packaging: Migration, Toxicity, and Management Strategies
Science
19 Mar 2024 | Environ Sci Technol
This study systematically maps evidence of PFAS in migrates and extracts of food contact materials, revealing the presence of 68 PFAS, predominantly perfluorocarboxylic acids and fluorotelomer-based compounds, highlighting the need for international regulations to limit PFAS as a group in food packaging for human and environmental safety.

Evaluation of per- and polyfluoroalkyl substances (PFAS) in landfill liquids from Pennsylvania, Colorado, and Wisconsin
Science
19 Mar 2024 | Chemosphere
Average PFAS levels in landfills from Pennsylvania, Colorado, and Wisconsin were 6,900, 22,000, 280, and 260 ppt in leachate, gas condensate, stormwater, and groundwater, respectively, with variations attributed to landfill design and local climate and higher PFAS levels in leachate exposed to open air and in groundwater near landfills without bottom liners.

Per-and Polyfluoroalkyl Substance Exposure Risks in US Carceral Facilities
Science
15 Mar 2024 | AJPH
To evaluate the risk of exposure to PFAS among the US incarcerated population, this study analyzed the geographic proximity of carceral facilities to known or likely PFAS contamination sites, finding that 5% of facilities are located within the same watershed boundaries as PFAS contamination sources, with implications for health inequities and the need for environmental monitoring in prisons.
