Per- and polyfluoroalkyl substances (PFAS) are a group of highly persistent chemicals that are known to bioaccumulate (become concentrated inside the bodies of living things) in food webs (food chains that show the feeding relationships within an ecosystem). Lab and field studies suggest that exposure to PFAS may be harmful to avian (bird) reproduction although exposure and effects are poorly understood.

In this presentation, Abby Odegard, Emily Pavlovic and Allie Pesano will discuss a current project which focuses on understanding the exposure and effects of PFAS on three species of nesting songbird in the Twin Ports region of Minnesota.

Six sites with variable levels of environmental PFAS contamination have been established and were monitored during the summer of 2022.
