Raptors at the top of the food chain are particularly susceptible to chemical pollutants, especially the so-called “legacy pollutants” like DDT which are banned but still present in the environment. SFU PhD student Kate Fremlin will present results of her research on how toxins like DDT move up the earthworm – robin – Cooper’s hawk food chain. She sampled these creatures (or their eggs, in the case of the hawks) throughout Metro Vancouver and analyzed the tissues for legacy toxins and newer toxins of emerging concern. Learn about the basics of biomagnification from Kate and how this process can affect top-level predators, including us.
