In a new study published in Environmental Science and Technology Letters, fluorinated high-density polyethylene plastic containers — used for household cleaners, pesticides, personal care products and, potentially, food packaging — tested positive for PFAS.

“Not only did we measure significant concentrations of PFAS in these containers, we can estimate the PFAS that were leaching off creating a direct path of exposure,” said Graham Peaslee, professor of physics in the Department of Physics and Astronomy at Notre Dame and an author of the study. In 2021 the EPA announced its PFAS Strategic Roadmap — promising to act on widespread exposure to PFAS. The plan includes developing a more comprehensive understanding of the health and environmental effects of PFAS exposure, preventing further contamination of air, land and water, and addressing the need for cleanup of PFAS already in the environment.
Analysis of the containers found parts-per-billion levels of PFAS that could migrate into both solvents and food matrices in as little as one week.
