TL;DR: The diagenetic behavior of anthropogenic mercury accumulated in sediments of the Saguenay Fjord (Canada) was investigated in this article, where box-cores taken along its main axis and in the St. Lawrence estuary were analyzed for bulk sediment and porewater total and methyl-mercury concentrations as well as a number of other chemical variables.

TL;DR: An epidemiologic study was carried out on an isolated population of beluga whales residing in the St. Lawrence estuary (Quebec, Canada) and major findings were a high prevalence of tumors, a high incidence of lesions to the digestive system, and some evidence of immuno-suppression.

TL;DR: The first high-resolution profiles of methylmercury concentrations in pore waters extracted under rigorous oxygen-free and trace metal clean conditions from organic-rich contaminated marine sediments were reported in this paper.

TL;DR: In this paper, the Saguenay Fjord sediments were collected along the main axis of the fjord and the acid-volatile sulphides (AVS) to pyrite ratio was found to exceed 1 and reaches values as high as 7.

TL;DR: Interaction between selenium and mercury in aquatic organisms is real but the true antagonism between these two elements has not yet been clearly shown.
