- New study traces PFAS in Great Lakes food webs over 40 years
A University of Notre Dame study analyzed 42 years of data to track PFAS chemicals in the Great Lakes food web, finding lower concentrations in Lakes Michigan, Huron, and Superior compared to Ontario and Erie. The study noted a decline in PFOS levels over two decades following its industry phase-out but highlighted bioaccumulation in predators like salmon and eagles.
