蚕豆根尖细胞微核技术监测实验室有机废水的污染研究

目的]对生物及化学类实验室的有机废水进行遗传毒性和污染效应的研究。方法]将实验室条件下制备环己酮时所排有机废水逐级稀释成8个梯度浓度，采用蚕豆（Viciafaba）根尖细胞微核技术进行检测。结果]不同浓度梯度的实验室有机废水对蚕豆根尖细胞有遗传毒性，在一定浓度范围内，随着废水处理浓度增大，蚕豆根尖细胞微核率、污染指数和有丝分裂指数逐渐增加；但浓度过高，反而会抑制蚕豆根尖细胞微核的形成和有丝分裂的进行。结论]实验室有机废水有明显的遗传毒性和环境污染效应，可以利用蚕豆根尖细胞微核技术对其污染效应进行监测和评价，实验室废水必须进行合理的处理（稀释或吸附消除重金属）方能排出。

Study on Organic Wastewater Monitoring of Laboratory Using MCN Test of Vicia Faba Root Tips

Objective] The genetic toxicity and pollution effects of biological and chemical organic wastewater were studied. Method] Organic wastewater which was formed during the preparation of cyclohexanone were diluted eight concentration gradients and detected using MCN test of Vicia faba root tips. Results] The results showed that different concentration gradients of organic wastewater had genetic toxicity. In certain concentration range, with the rising of organic wastewater treatment concentration, rate of m...
