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.

Predictors of Serum Per- and Polyfluoroalkyl Substances Concentrations among U.S. Couples Attending a Fertility Clinic
Science
19 Mar 2024 | Environ Sci Technol
PFAS concentrations among couples seeking fertility treatment in the U.S. were correlated within couples and with factors like race, body mass index, and dietary habits, particularly fish and shellfish consumption, shedding light on potential interventions to mitigate exposure in the preconception period.

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.
