肺癌矿工肺组织中蓄积矿物的研究

Study of Minerals of Lung Cancer in Tin Miners

应用 X线衍射及能谱方法分析患肺癌的云锡矿工27例和当地居民3例肺组织中蓄积的矿物。结果表明,矿工肺内蓄积的矿物量比居民大,成分复杂。云母与滑石最多见,次为石英与赤铁矿,未检出含砷矿物。原子荧光法检出了元素砷,不少矿工肺砷量与居民接近,未见肺砷量与井下采矿工龄的平行关系。

A mineral retention study was conductedon 30 pathologic specimens in order to findthe relationship between the minerals deposi-tion with occurrence of lung cancer. The spe-cimens were collected from Yunnan Tin mi-ners. X-ray diffractional method and analyicalelectronmicroscopy (EDXA) showed moreminerals in the miners lung than that in oth-ers. Most of dusts contained mica, talc, andthen haematid and Quartz. Arsenic were notfound. Atomic fluorecentmetry showed arse-nic but its level about the same as the popu-lation around the mining area.
