摘要：

A survey of mercury levels in river water and sediments, forest soils, fish, air and human hair is presented for the Madeira River watershed in southwest Amazonia, Brazil. Mercury levels appeared particularly high in tributary rivers close to major gold-mining areas. High Hg levels in fish (up to 2.7 ppm) were also found in such areas. Atmospheric Hg levels were mostly close to background, but can reach high values (3.2 mg/m3) in the proximity of the Hg-Au reburning complex. Human-hair levels, however, reach values up to 26.7 ppm, indicating high exposure rates of the local population.
