摘要：

Total mercury concentrations were determined in muscle, liver and kidney of Cichlia ocellaris and Colossoma macropomum sampled at Tapajos and Carnapijo Rivers in Amazon ecosystem during the flood period of 2009. In background area the highest levels of mercury were observed in liver of piscivorous (0.3 +/- 0.03 ug/g dry wt) and non piscivorous fish (0.20 +/- 0.1 ug/g dry wt), but in contaminated area the highest level of mercury in piscivorous fish was detected in liver (0.45 +/- 0.27 ug/g dry wt) and in muscle (0.26 +/- 0.05 ug/g dry wt) of non piscivorous fish. These results suggested that the presence of anthropogenic source plays a key role in the pattern of mercury distribution in fish tissues.
