In the Arctic Deep, Clues to Mercury in the Food Supply
Thousands of kilometers north of anywhere, Dr. Lars-Eric Heimbürger is studying the problem of mercury contamination in Arctic animals. His research is focusing on the microbial transformation of inorganic mercury into its most toxic form, methylmercury, which biomagnifies along the food chain, from water, to plankton, ultimately reaching harmful levels in predatory fish, but also ringed seals, beluga whales and polar bears. As human activities change the climate and mercury emissions, his research will help us understand and anticipate the impact on fish stocks and people's exposure via the food supply.
