根据推溶性多金属含砷矿、氧子体及吸烟是导致云锡矿工肺癌高发的主要因素，开展了云锡矿工人群及动物的细胞遗传毒理学实验，用不同成份、不同剂量、同类矿山矿尘，分别对大鼠气管灌注和吸入不同剂量的氧及氧子体，氧、尘复合，被动吸烟加灌尘，10批71组2560只大白鼠遗传毒理 According to the solubilization of polymetallic arsenic minerals, oxygen seeds and smoking, which are the main factors leading to the high incidence of lung cancer among Yunnan tin miners, the cytotoxic genetic experiments of the workers and animals in the Tin Tin Mine were carried out using different compositions, different doses, and similar mines. Dust, respectively, rats tracheal infusion and inhalation of different doses of oxygen and oxygen, oxygen, dust compound, passive smoking plus dust, 10 batches of 2 670 rats of 71 groups of genetic toxicology
