Total Mercury Distribution in the Barents Sea and the Arctic Ocean Surface Sediments
Kull, Laura Maria (Master thesis, 2022)Mercury (Hg) has been a trace metal of interest for decades due to its neurotoxic effects on humans and other organisms coupled with its ability to bioaccumulate and biomagnify. Areas like the Arctic and the ocean floor ...
