Birds of prey act as sentinels to warn of forever chemicals

A new paper investigates how raptors, or birds of prey like hawks and eagles, act as a sentinel species that can reveal the level of forever chemicals in the local environment. The forever chemicals, or PFAS, are especially high in species that eat fish. The review titled, "Raptors as Sentinels: Unveiling the Environmental and Health Risks of Pfas Contamination," published in Toxicology Mechanisms and Methods, provides a comprehensive analysis of the current scientific data on per- and polyfluoroalkyl substances (PFAS), a persistent environmental contaminant of global concern.
