本文采用 ILO 国际尘肺分类法对两个锡冶炼厂冶炼工人 X 线片,两类小阴影形态大小(p、q、r,s、t、u)和密集度与其粉尘性质和剂量作相关分析,为确定该粉尘危害性质提供依据。一、一般情况此次调查的甲、乙两个厂分别于1952、1958年后改鼓风炉炼锡为反射炉炼锡。鼓风炉炼锡烟尘很
In this paper, ILO international pneumoconiosis classification was used to analyze the correlation between the two small stencil shape sizes (p, q, r, s, t, u) and their intensities with the properties and dosages of dust of two tin smelters, In order to determine the hazardous properties of the dust to provide the basis. First, the general situation The investigation of A, B two plants in 1952, 1958 after the blast furnace to make tin for the refiner smelting tin. Blast furnace smelting tin is very dust
