Contamination of the Arctic associated with persistent organic pollutants (POPs) and mercury poses a grand challenge to environmental scientists due to their persistency, potential to bioaccumulate in the food web and possible adverse effects on the ecosystem.
This symposium will focus on the sources, transport and fate processes, bioaccumulation and toxicity of POPs and mercury in the Arctic.
The number of participants is limited to 30.
