摘要
在测定目前各作业点粉尘浓度,收集历年粉尘浓度测定结果和接触石棉尘工人石棉肺发病情况的基础上,计算累积接尘量与石棉肺发病关系,用寿命表分析法和Logistic回归模型,预测石棉肺发病趋势。若工人工作30年,容许石棉肺患病率为3%,接触剂量为40~58根/年,车间空气中石棉纤维容许浓度为13~20f/ml。要达到此目标。
After measuring the
current concentration of all workplaces,collecting the past mass concentration records and
investigating the prevalence of asbestosis among chrysotile workers,and after transferring the
past mass concentration into fibre concentration,the dose\|response relationship is established.
The prevalence of asbestosis is predicted by the analytical method of life table and the model
of logistic regression.The 3% predicted prevalence of asbestosis corresponds to an exposure
of 4058 f/yr.Suppose workersworking age being 30 years,a recommendation for a maximum
allowable concentration of 1\^32\^0 f/ml would be appropriate.If so,effective dust control
measures must be taken.
