Notre Dame researcher Graham Peaslee reveals how man-made PFAS (per- and polyfluoroalkyl substances)—commonly known as forever chemicals—end up in our food and, eventually, the environment. These chemicals persist for thousands of years, posing a significant environmental threat and health risk.In the first of a three-part video series titled "PFAS: The Forever Problem," we discuss how PFAS is quickly becoming one of the largest environmental problems the U.S. has ever faced and the cutting-edge techniques the University of Notre Dame is developing to measure and mitigate their impact on our environment and health.
