摘　　要：应用蚕豆根尖细胞微核技术,对大庆市4个采油厂聚驱的石油采出水遗传毒性进行分析研究。结果表明:经聚合物驱油的石油采出水处理过的蚕豆根尖细胞,其染色体均发生异常,出现断片、桥以及滞后染色体等现象,有明显的微核效应和遗传毒性,加水稀释对于减轻其毒性的作用甚小,如果不加处理地排放将会给生态环境造成危害。Horsebean root tips were selected as materials to detect micronucleus causing by polymer-flooding waste water sampled from four oil production plants in Daqing city. The results showed that at certain concentration,the four samples all could incite Vicia faba root tip ceils to produce chromosomal abnormalities such as fragments, bridge and lagging chro- mosomes. All these resuhs proved that there was great genotoxicity to organisms caused by oil produced water,and therefore could not discharge it to ecological environment arbitrarily in order to avoid causing great harm.
