Abstract |
This report is a review of environmental levels of mercury based on published reports and other information sources. Mercury levels are reported for the atmosphere, surface and ground waters, drinking water, sediments, soil, terrestrial and aquatic biota, and man. The behavior of mercury in the environment is also discussed. Higher than ambient levels of mercury are found near mercury mines, geothermal steam fields, power plants, incinerators, sewage treatment plants, some industrialized areas, and indoors where mercury is used. The release of mercury from natural sources to air and water is double the man-related losses to these media. The levels of mercury in biota are variable, depending on food habits and environmental conditions. The highest levels occur in animals at the top of the trophic structure. Mercury levels in tissues of humans are elevated in chlor-alkali industry workers, in dentists, in people from areas with natural mercury deposits, and in urban populations as compared with the rural. |
