| 摘 要： | 利用六价铬离子(Cr6+)染毒泥鳅(Misgurnus anguillicaudatus),采用微核试验法,以外周血红细胞的微核率为指标,研究Cr6+对泥鳅的遗传学毒性。结果显示,Cr6+对泥鳅具有一定的毒性;当浓度增加或染毒时间延长,均会引起微核率增加,而且高浓度(160～200 mg/L)和长时间染毒(8 d)均出现了显著性差异,微核率与染毒浓度以及与处理时间之间均有较为明显的正相关性,即具有剂量效应和时间效应;研究表明含铬废水排入环境对水生生物会造成不同程度的影响。

| Abstract: | Abstract :Effects of Cr6+ on outerblood corpuscle micronuclei in erythrocyte of loaches were studied. The result s showed that the Cr6+ can poison loaches in some conditions.There are significant correlation between rate of the micronuclei and the concentration , and so did the micronuclei rate and the treating time. |

| Keywords: | Cr6+ Misgurnus angullicaudatus micronuclei rate |
