PFAS present throughout the Yadkin-Pee Dee river food chain

Researchers from North Carolina State University have found per- and polyfluoroalkyl substances (PFAS) in every step of the Yadkin-Pee Dee River food chain, even though the river does not have a known industrial input of these compounds. The study examined the entire aquatic ecosystem for PFAS compounds and identified strong links between ecosystem groups that lead to biomagnification, the process that leads to greater concentrations of these substances in animals that sit higher on the food chain—including humans.
