摘要
本文使用蝌蚪红细胞微核率作为指示器研究明通河污水和用污水土地处理系统处理后水质的致突变性。蝌蚪在各种水样品中暴露7天。采心脏血制片。在对照组中,微核率分别为4.40‰和4.68‰。1/4明通河污水组诱发蝌蚪的微核率是17.01‰。同对照组相比有明显的差异。
In this paper, we used frequency of micronueleated erythrocytes in the tadpoles as the indicator to study the mutagenicity of wastewater of Mingtong River and various water quality treated with SLDS. The tadpoles were exposed in various water sample for 7 days. Smears of the cardiac blood samples were prepared. The frequencies of micronueleated erythrocytes in two control groups were 4.40‰ and 4.68‰, respectively. The frequency of tadpole miero-nucleated erythocytes induced by wastewater from Mingtong River was 17.01‰. There was significant difference in comparison with control groups.
