锗属于稀有元素，主要存在于煤中，广泛应用于电子工业，如半导体的生产。冶炼中除接触大量的煤尘外，还产生一些有毒物质，如ＣＯ、Ｈ２Ｓ、ＮＯ２、ＨＣｌ等。我们对云南省某锗冶炼厂的作业工人进行了职业危害调查，报告如下。１对象和方法１．１对象随机抽样选择了１０... Germanium is a rare element mainly found in coal and is widely used in the electronics industry, for example in the production of semiconductors. Smelting in addition to contact with a large number of coal dust, but also produce some toxic substances, such as CO, H2S, NO2, HCl and so on. We conducted a survey on occupational hazards of workers at a germanium-smelting plant in Yunnan Province. The report is as follows. 1 objects and methods 1.1 random sampling of objects selected 10 ...
