Description:
Mercury methylation typically occurs along the redox boundary between oxic and anoxic conditions in the sediment and water column of surface waters. Previous studies have suggested that the dominant zone of methylation in lakes and reservoirs shifts from the sediment into the water column during periods of anoxic stratification, however, studies measuring methylmercury (MeHg) production in both sediment and the water column simultaneously remain limited. Understanding the importance of sediment methylation on water column MeHg concentrations has implications for management strategies aimed at reducing MeHg production.
