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。
In this study, atomic absorption spectrophotometry was used to determine the content of 12 kinds of anti-cancer trace elements in mine dust with high and low incidence of lung cancer, the ratio of anti-cancer to anti-cancer Comprehensive effect ratio analysis of the risk of lung cancer. The results showed that the contents of iron, cadmium, lead, antimony, arsenic and zinc were high in mine dust with high incidence of lung cancer, while the content of selenium and manganese in dust was low, and the comprehensive effect ratio was also higher than that of control mine. Prompt miners of lung cancer and mine dust in carcinogenic microelement content has a certain relationship.
