Mercury is emitted to the atmosphere from natural and anthropogenic sources such as volcanic activities and burning of fossil fuel. In the atmosphere, Hg is transported to pristine environments, such as the Arctic Ocean, where it accumulates as methylmercury in aquatic food webs to concentrations that are of concern for human to wildlife health. The aim of this project is to evaluate data on gaseous mercury (Hg) in ambient outdoor air collected during the Arctic 2018 expedition using the Swedish icebreaker Oden as platform. Back trajectories of air masses from adjacent European areas will be used in order to trace origins of Hg and local and regional point sources. This project is done in collaboration with Lisa Gustafsson och Josefin Gunnarsson (masterstudents, Chalmers University of Technology).
