| 摘 要： | 采用红细胞微核和观察生长指标分析的方法探讨Pb2+、Cu2+、Hg2+三种重金属离子对青蛙蝌蚪生长发育的毒性影响。结果表明:Pb2+、Cu2+、Hg2+使黑斑侧褶蛙蝌蚪红细胞核异常率明显提高,其平均红细胞核异常率分别达到3.51‰、2.20‰、2.52‰,与对照组相比增长了6.02、3.40和4.04倍。重金属离子在一定的处理时间和质量浓度下对蛙蝌蚪红细胞有显著的诱突变作用。另外,实验组的体长、尾长均低于对照组,Pb2+处理组中的蝌蚪出现了明显的畸形现象。

| Abstract: | The Toxic effect of heavy metal ions on the growth and development of the tadpoles of Pelophylax nigromaculatus is examined through analyzing micronuclei of red blood cells and observing the growth index.The result shows that Pb2 +,Cu2 + and Hg2 +could raise the erythrocytes of abnormal nucleus remarkably and their average rates are 3.51‰、2.20‰、2.52‰ respectively.Compared with the control group,the erythrocytes of abnormal nucleus rate increased to 6.02,3.40 and 4.04 times respectively.The experiment indica... |
