In the United States, PFAS chemicals are so ubiquitous — found in everything from frying pans to skincare — that nearly all of the country’s population likely has measurable levels of the so-called “forever chemicals” in their blood. It’s only in the last few decades that the public and scientists started untangling the health and ecological risks associated with some of the manufactured compounds, which earned their nickname because they don’t break down easily in the environment.
Now, new research from the University of Notre Dame has deepened our understanding of how PFAS can filter through ecosystems and move up the food chain to get to people.
