【Abstract】 This paper analysed concentrations of heavy metals contained in the body of fishes, algae, zoobenthos ect. hydrobios which lived in sewage treatment system of Nanxishan hospital of Guilin. The biological enrichment constants have been calculated. It is found that the enrichment capability sequece of different kind of fishes, enrichment capabilityof same kind of fishes and enrichment capability of different organ of fishes is different to five kinds of heavy metals.更多还原
