| 摘 要： | 利用姐妹染色单体交换率（ＳＣＥ）的增加与否，作为细胞遗传毒理学的指标来评价一些理化因子的诱变性，是检测化学致突的方法之一，通过对某碳素厂接触生产性煤焦沥青烟气的工人人体外周血淋巴细胞ＳＣＥ观察表明，车间接触组工人ＳＣＥ明显高于非接触组工人（约１．６７倍）；在接触线组中，在者ＳＣＥ高于非吸烟者；同为吸烟者，接触组工人ＳＣＥ高于非接触组工人（约１．４８倍）。结果提示示煤焦沥青烟尘能引起工人ＳＣＥ的改变

| Abstract: | Using either increased or not of sister chromatid exchange as an index of genetical toxicology to evaluate mutation of physical and chemical factors, it can be used as one of the method for determination of chemical mutagen. Through observation of SCE of exposed people in certain carbon black factory, it showed that: the SCE of exposed people was obviously higher than non-exposed people (about 1.67-fold). Among the group of exposed people, the SCE of cigarette smoking people was higher than that of non-smoking one. |
