摘要
目的 研究金属矿工与煤工尘肺尸检肺内粉尘、游离二氧化硅及元素的含量。方法 3 6例矿工尸检双肺样品 ,分别用Guert法、红外分光扫描法、原子吸收分光光度法测定肺内粉尘、游离二氧化硅及金属元素含量。结果 随肺内滞留粉尘、游离二氧化硅含量的增加 ,尘肺病变加重 ;相同期别的金属矿工与采煤工尘肺 ,肺内粉尘量前者低于后者 ,游离二氧化硅量二者基本接近 ;肺组织中元素含量金属矿工高于采煤工 ,并与尘肺期别无关。结论 肺内粉尘、二氧化硅含量与尘肺病变程度呈一致性 ,在采煤工尘肺病变因素中 。
Objective To study the contents of dust,free silica and metal elements in the lungs of metal and coal miners in autopsy.Methods Specimens of both lungs were collected form 36 miners in autopsy.Contents of dust,free silica and metal elements in the lungs were determined by Guert method,infrared photospectrometric scanning and atomic absorption spectrometry.Results With increase in contents of dust and free silica detained in the lungs,silicosis exacerbated.Dust content in the lungs was less in metal miners than that in coal miners and that of free silica was basically equal in both of them.Contents of metal elements were greater in metal miners than that in coal miners,independent of their staging of silicosis.Conclusion Contents of dust and free silica in the lungs coincided with severity of silicosis.Silica dust plays a more important role than coal dust does in pathogenesis of coal worker pneumoconiosis.
