摘要
目的 研究电镀厂的生产用水、未处理的生产废水以及已处理水对蚕豆胚根根尖的细胞遗传学毒性效应。方法 采用蚕豆根尖细胞的微核试验方法和染色体畸变试验方法 ,以电镀厂的生产用水、未处理的生产废水以及已处理水为诱变剂 ,测定蚕豆根尖细胞的微核率和染色体畸变率。结果 诱发蚕豆根尖细胞的微核率和染色体畸变率的大小均依次为未处理的生产废水 >已处理水 >生产用水。结论 该电镀厂的未处理的生产废水以及已处理水对植物根尖细胞具有遗传毒性效应 。
Objective The cytogenetic toxic effects of waste water fr om plating plant on the cell of vicia faba root tip were studied. Methods As mutagen of the productive water,the productive waste water and the treated water,the micronucleus test and chromosome aberrati on test were used to assay the rate of micronucleus and chromosome aberration. Results The rate of micronucleus and chromosome aberratio n of vicia faba root tip cell in turn were the productive waste water,the tr eated water and the productive water. Conclusion The productive waste water and the treated wat er of this plating plant had some cytogenetic toxic effects,and induced differen t kinds of chromosome aberration.
