摘要

The mercury content in 158 fishes and 28 mussels in the Second Songhua river were detected. The rangeof mercury concentrations in fishes and mussels was 0.02-0.66 mg/kg and 0.002-0.056 mg/kg，respectively. Thehistory change of mercury content in fishes was analyzed in this paper. From upstream to downstream, the averagemercury concentrations in fishes increased with the increase of the distance to the headstream，then decreased in thedownstream of Wujiazhan town (sampling site). The fact illuminated that the source of mercury contamination wasmercury in sediment. In the different species of fishes，the mercury concentration in Parasiburus asvtus was the high-est and the order of mercury distribution in fishes was: the mercury value in fishes in the river bottom ＞ that in fishesin the surface and that in predacious fishes ＞that in herbivorous fishes. In the investigation, there were amount of fish-es whose mercury value exceeded the criterion for that in fishes that suggested that the mercury contamination in theSecond Songhua River have not completely been eliminated until now.
