摘要
采用人体外周血淋巴细胞体外培养的方法，对兰州市不同地区５个采样点大气总悬浮颗粒物（ＴＳＰ）有机提取物进行了姐妹染色单体交换（ＳＣＥ）试验。结果表明，５个样品对ＳＣＥ率均有不同程度的影响，并具有较好的剂量－反应关系。其中铁路局和西固点ＳＣＥ率增高尤为显著，对照点榆中则增高微弱。
he effect of TSP in Lanzhou region on SCE in human peripheral blood lymphocytes was detected in vitro.The result indicated that TSPinduced SCE frequencies were increased with definite doseresponse relationships and that SCE frequencies induced by TSP in Lanzhou railway Bureau and Xigu were higher than Yuzhong.
