Carbon dynamics control comtemporary mercury burial in Arctic Ocean sediments Open
Mercury (Hg) contamination is a familiar concern in the Arctic. However, this study shows that variations of Hg concentration in 30 sediment cores collected across the North American Arctic Margin (NAAM) and in the deep central Arctic Ocea…

Mercury Accumulation Pathways in a Model Marine Microalgae: Sorption, Uptake, and Partition Kinetics Open
The accumulation of dissolved mercury (Hg) by phytoplankton is the largest concentration step along aquatic food chains. However, the cell uptake mechanisms remain unclear. In this study, the marine haptophyteTisochrysis lutea, a mo…

Mercury in Marine Mussels from the St. Lawrence Estuary and Gulf (Canada): A Mussel Watch Survey Revisited after 40 Years Open
Various species of marine mussels have been used, in the last 50 years, as sentinel organisms for monitoring metal contamination along marine coasts. There are two main reasons for this: these mollusks concentrate metals in their soft tiss…
