摘　　要：通过对水样重金属、溶解氧、总氮、氨氮等水质指标的测验,以蚕豆种子为研究材料,采用根尖细胞微核实验和有丝分裂实验方法,研究电厂废水的毒性效应和环境的影响.结果显示:电厂废水各指标均达标,水质良好,对周围生态环境影响较少,但可抑制蚕豆根尖细胞有丝分裂和染色体损伤,具有一定的遗传毒性.Based on the test of the heavy metals, dissolved oxygen, total nitrogen, ammonia nitrogen and other water quality indexes of the water sample, the study is conducted through micronucleus experiment of root tip cell of fava and mitosis experiment method, using the fava seeds as research material, to research the toxic effect of power plant wastewater and the environment. The results show that every indicator of power plant wastewater reaches the standard; the water quality is good, which has less impact on the surrounding ecological environment. However, such wastewater could cause mitotic inhibition and chromosome damage in the root - tip cells of fava, which has a certain genotoxicity.
