Although mercury (Hg) is toxic at all valence states, organic Hg, especially
monomethylmercury (MeHg, CH3Hg+, methylmercury), is more toxic than inorganic Hg (Hg …

Recent studies have shown that climate change is already having significant impacts on
many aspects of transport pathways, speciation and cycling of mercury within Arctic …

It was discovered in 1995 that, during the spring time, unexpectedly low concentrations of
gaseous elemental mercury (GEM) occurred in the Arctic air. This was surprising for a …

The widely accepted conceptual model of mercury (Hg) cycling in freshwater lakes
(atmospheric deposition and runoff of inorganic Hg, methylation in bottom sediments and …

Methylation of inorganic mercury in the aquatic environment has been considered to be
largely the result of biological processes, primarily involving sulfate-reducing bacteria …

Mercury in the Arctic is an important environmental and human health issue. The reliance of
Northern Peoples on traditional foods, such as marine mammals, for subsistence means that …

There has been increasing concern about mercury (Hg) levels in marine and freshwater
organisms in the Arctic, due to the importance of traditional country foods such as fish and …

The release of organic contaminants from melting snow poses risks to aquatic and terrestrial
organisms and to humans who rely on drinking water and food production from regions that …

Environmental context. Mercury (Hg) occurs at high concentrations in Arctic marine wildlife,
posing a possible health risk to northern peoples who use these animals for food. We find …

Methylmercury is a potent bioaccumulating neurotoxin that is produced by specific
microorganisms that methylate inorganic mercury. Methylmercury production in diverse …
