接触砂岩粉尘工人的尘肺病预测研究

A Study of Forecasting on Pneumoconiosis Morbidity Level among Workers Exposed to Silica Dust

目的：对玻璃生产原料开采和加工粉尘作业工人尘肺发病水平进行预测，为制定有效防护措施提供科学依据。方法：应用寿命表法求得接尘剂量与发病水平的关系。结果：发病水平随接尘剂量的增高而增高，求得了两者之间的回归方程。结论：如果把发病概率控制在５％以下时，在粉尘浓度１ｍｇ／ｍ３的条件下，工作年限不应超过３７年；如控制在２ｍｇ／ｍ３，工作年限不应超过１８．５年。

Objective: Forecast morbidity level among workers exposed to dust of glass raw and processed material and provide scientific data for making the effective proventive measure.Methods: Seek interrelation between dust dose and morbidity level with the method of life table. Results: The morbidity level increased with dust dose increased and we obtained an equation of regression between them.Conclusion: Service munber of years of workers can not exceed 37 years under dust concentration 1 mg/m3 circumstance if morbidity probability is limited to 5% and service number of years cannot exceed 18.5 years under dust concentration 2 mg/m3.
