废旧干电池对泥鳅的致毒作用

Toxicity of Used Cells on Loach

以抗污染能力强的泥鳅(Misgurnus anguillicadatus)为实验材料,研究了废旧干电池污染的水源对水生生物的毒害作用。结果表明,泥鳅受毒害程度与水体中废旧干电池的数量和暴露时间成正相关关系;对受毒害但未死亡的个体断尾取血,显微镜下观察血红细胞的形态、结构,发现在废旧干电池污染的水体中残存的个体,其血红细胞的变异率远远超过生活在正常水体中的个体。

We researched the toxicity of used cells on hydrobiology such as Loach, which has a strong ability of adjusting itself to polluted environment. The result showed that the degree of toxicity on Loach was well correlated with the number and the time of used cells exposed in water; For those suffered but not died animals, their red blood cells under the microscope were investigated, we found that the rate of red blood cell nuclear abnormity of those animals living in the water polluted by used cells well exceed those living in normal water.
