摘要
本研究用原子吸收分光光度法测定肺癌高、低发矿山矿尘中12种致、抗癌微量元素的含量,用单个元素相比的致/抗比值和多个致、抗癌元素相比的综合效应比值分析肺癌发生的危险性。结果发现肺癌高发矿矿尘中铁、镉、铅、锑、砷和锌的含量较高;而粉尘中硒和锰的含量较低,综合效应比值也高于对照矿。提示矿工的肺癌高发与矿尘中致癌微量元素含量过高有一定关系。
The contents of eight carcinogen elements and four anticarcinogen elements in the tin mine dust were determined by the atomic absorption srectrometry. The single ratio(SR) standed for that the content of one carcinogen element was compared with one anticarcinogen element (such as As/Se). The comprehensive effect ratio (CER) was that the total quantities of carcinogen elements were compared with those anticarcinogen elements. The results showed that in change Po tin miner (high lung cancer incidence mine) the contents of Fe, Cd, Pb, Sb, As, and Zn in the mine dust, no matter SRs or CERs, were significantly higher than those of control. It suggested that there would be some relationship between the carcinogen elements in mine dust and the lung cancers of miners.
