Description:
A mercury-contaminated freshwater pond, Reality Lake (RL), was investigated in the vicinity of Oak Ridge, Tennessee. he original source of contamination was a nuclear weapons plant where elemental mercury was used from the 1950s to 1970s to enrich lithium isotopes for the production of hydrogen-bombs. astewater draining from the plant contained mercury concentrations at ug/L levels, and as a result, fish in the creek downstream from RL occasionally contain Ch3Hg(I) at concentrations above the regulated level of 1 mg/L. nitial results indicated that active bacteria originally isolated from RL affected the speciation and concentration of mercury in flask incubations and in microcosms that simulate the cycling of mercury in the pond. hus, treatment of such contaminated aquatic systems with active organisms may be a feasible approach to in situ mercury remediation.
