At the invitation of the Helmholtz Center Hereon, experts exchanged views for the first time at a workshop on the problems caused by pollution in Polar regions.

Food preferences determine pollution levels in orcas

Dr. Michael Wenger

In the case of orcas in the Arctic, individual food preferences determine how heavily an animal is contaminated with pollutants.
