| 摘 要： | 在实验室条件下以不同浓度Cr^6 (0．122、0．670、1．219、3．657、10．971和32．913mg／L)水体染毒鲤鱼种40d，微核试验结果表明：处理组铬浓度的提高，其嗜多染红细胞微核率相应提高。鲤暴鳝于Cr^6 3．66～32．91mg／L时，铬处理鱼微核细胞率较对照组鱼有明显差异。鱼肌肉、鳃、肝和肾组织内的Cr^6 残留量同其微核率呈正相关关系。

| Abstract: | The Carps were exposed to Cr 6+ at concentrations in the range from 0.12, 0.67, 1.22, 3.66, 10.93 and 32.91 mg/l for 40days. The results of the micronuclei test were showed that the polychromatocytes micronuclei frequencies of Carps which the Carps were exposed at the chromium higher dose. When Cr 6+ were exposed to dose 3.66to 32.91 mg/l, the micronuclei frequencies were significantly increased than the control fish. The residue of Cr in the Carps' musuts,gills,liver and kidney in well correlated with their micronulei frequeclies. |
