矽肺发病与粉尘吸入量有密切关系,而粉尘中游离二氧化矽含量的高低及其分散度的大小,又是决定矽肺发病的重要因素。为了给修订卫生标准提供依据,我们采用寿命表法对重庆钢铁公司耐火材料厂及贵州汞矿的接尘工人发病资料进行了分析,以期能为我国研究矽肺发病与接尘量的关系在方法上提供几个实例。
Silicosis and dust inhalation is closely related to the amount of free silica in the dust content and the size of its dispersion is an important factor in determining the incidence of silicosis. In order to provide the basis for the revision of the hygiene standards, we used the life table method to analyze the incidence data of dust-exposed workers in refractory plants of Chongqing Iron and Steel Company and mercury mine in Guizhou in order to study the relationship between the incidence of silicosis and the amount of dust- Provide a few examples.
