sediment microbial community structure and mercury methylation in mercury-polluted clear lake, california.spatial and temporal variations in sediment microbial community structure in a eutrophic lake polluted with inorganic mercury were identified using polar lipid fatty acid (plfa) analysis. microbial community structure was strongly related to mercury methylation potential, sediment organic carbon content, and lake location. pore water sulfate, total mercury concentrations, and organic matter c/n ratios showed no relationships with microbial community structure. seasonal changes and changes potent ...200010742230
sediment microbial community composition and methylmercury pollution at four mercury mine-impacted sites.mercury pollution presents a globally significant threat to human and ecosystem health. an important transformation in the mercury cycle is the conversion of inorganic mercury to methylmercury, a toxic substance that negatively affects neurological function and bioaccumulates in food chains. this transformation is primarily bacterially mediated, and sulfate-reducing bacteria (srb) have been specifically implicated as key mercury methylators in lake and estuarine sediments. this study used phosph ...200314502415
