New research traces how ‘forever chemicals’ move through the Great Lakes and into people

This research sheds light on how persistent and harmful "forever chemicals" called PFAS travel through the Great Lakes ecosystem and eventually end up in human bodies. By analyzing over 40 years of data, scientists mapped how PFAS levels change across various species in the region's food chain. This work is crucial because PFAS are linked to serious health issues, and understanding their movement helps authorities devise better strategies to mitigate their impact on both wildlife and human health. The findings underscore the need for stricter regulations to prevent further contamination of our water sources.
