The role of organisms on the fate of mercury in aquatic environments was evaluated. Objectives were to quantitate transformations of mercury in water-sediment systems, to investigate the fate of elemental mercury in microbial growth systems, and to measure the concentration of total and methylmercury in food chain organisms. In anaerobic water-sediment systems spiked with calcium acetate and mercuric chloride, elemental mercury was produced in larger quantities than methylmercury. In water-sediment systems, added elemental mercury was oxidized and deposited in the sediments where small amounts of methylmercury were formed. Six pure cultures of bacteria oxidized elemental mercury, but none formed methylmercury. In a stream receiving mercuric ion, mosquito fish contained more methylmercury than did tadpoles, snails, and aquatic insects. Algae did not contain methylmercury, even though their total mercury levels were high.
