The Detectives: Hunting toxic chemicals in the Arctic

Baby grey seals. Polar bears. Zooplankton on painkillers. How do toxic chemicals and substances end up in Arctic animals — and as it happens, native people, too?

Our guests on today's show are Bjørn Munro Jenssen, an ecotoxicologist at NTNU, Jon Øyvind Odland, a professor of global health at NTNU and a professor of international health at UiT —The Arctic University of Norway, and Ida Beathe Øverjordet, a researcher at SINTEF.

One of the most useful websites on arctic pollution is the Arctic Monitoring and Assessment Programme, AMAP. Rachel Carson's book is Silent Spring.

Here's a selection of articles from today's episode:
