Methylmercury bioaccumulation in benthic invertebrate assemblages in the Beaufort Sea

This study investigated methylmercury (MeHg) concentrations in Arctic benthic invertebrates from two shelf sites in the Canadian Beaufort Sea. A combination of carbon, nitrogen and sulfur stable isotopes and fatty acids were used to examine the influence of diet on MeHg concentrations in 476 individuals from 51 taxa of benthic invertebrates representing three different feeding guilds.
