42-Year Study Tracks 'Forever Chemicals' Contamination in Great Lakes Wildlife

A comprehensive 42-year study by University of Notre Dame researchers has tracked the movement and impact of per- and polyfluoroalkyl substances (PFAS), commonly known as 'forever chemicals,' across the Great Lakes region. The analysis of extensive biological records reveals how these persistent chemicals have infiltrated various wildlife populations. PFAS are known for their resistance to degradation, leading to long-term environmental contamination. The study highlights the widespread presence of these chemicals in the ecosystem and their accumulation in animals. This long-term tracking provides critical data on the environmental fate and biological effects of PFAS. The findings underscore the persistent challenge of 'forever chemicals' in aquatic environments. This research is vital for informing policy and remediation efforts aimed at protecting the Great Lakes.
