摘要
本文在某钨矿进行了呼吸性矽尘与矽肺的暴露～反应关系的研究。首先对该矿井下呼吸性粉尘与息扮尘浓度的关系进行了研究,把历史接尘资料中总粉尘浓度转换为呼吸性粉尘浓度。最后用Logistic多元回归模型对1151名工人的接尘资辩进行了处理,推算出在一定接尘条件下,呼吸性矽尘的容许浓度为0.24mg/m^3。
Study on exposure-response relatonship between respirable silica dustand silicosis was carried out.Firstly,the relationship between respirabledust concentration and total dust concentration was studied and data oftotal dust concentration in history converted to respirable dust concen-tration.Finally,allowable concentration for respirable silica dust (0.24mg/m3) was estimated by using logistic multiple regression model.
