本文对白云鄂博铁矿破碎车间粉尘和尘肺发病资料进行了回顾性调查。用寿命表法分析了该铁矿粉尘和尘肺发病的剂量—反应关系。结果表明,累计发病概率随接尘量的延长呈增长趋势。建议该矿山粉尘允许浓度以8mg/m~3为宜。
This paper retrospectively investigated the data of dust and pneumoconiosis in the Baiyunebo iron and steel mine crushing workshop. The life-table method was used to analyze the dose-response relationship between iron dust and pneumoconiosis. The results showed that the cumulative incidence of disease increased with the increase of dusting amount. The proposed mine dust concentration to 8mg / m ~ 3 is appropriate.
