摘要
采用微核试验法,对贯穿淮安城市中心、边缘、外围的3条主要河流里运河、废黄河、盐河水质诱发蝌蚪红细胞微核及核异常进行了比较研究.每条河水样又分为100%原样、50%,33.3%3个浓度组,以暴气后的自来水为对照.实验结果显示,毒染1周后,里运河、废黄河水质诱发蝌蚪红细胞微核率及核异常率均大于对照组(P<0.01),里运河水组诱发微核细胞率明显高于废黄河水组和盐河水组(P<0.01).而盐河水组诱发微核率及核异常率(33.3%浓度组)与对照组之间差异不显著(P>0.05).实验结果提示,淮安城区中心地段河流水质诱发蝌蚪红细胞微核率的影响明显高于外围,其水体中存在致突变物质.
By the method of tadpole micronuclei assay, the results of water quality inducing red blood corpuscle＇ s micro nuclear and abnormal core from three resources, water of center inner canal, abolished water in edge river and salt water of peripheral river, were compared. In each river water quality study, 100%, 50% and 33.0% of the original water concentration were divided with aired drink water as blank assay. Results shows that tadpole red blood corpuscles nuclear cell rate and core unusual cell rate from abolished inner canal water and Yellow River water show higher rote than contrasted group （ P 〈 0.01 ） after one week （ P 〈 0.01 ）. Especially for rote of the inner cannel water, it is marginally higher that the other two groups water （ P 〈 0.01 ）. Tadpole red blood corpuscles nuclear cell rate and core unusual cell rate in Salt River were not statically higher than that of the contrasted group. From the experimented resulted, it is concluded that there are mutational substances in inner cannel water.
