为探讨包头铝厂含铝粉尘与铝尘肺的剂量—反应关系,推算该类粉尘的容许浓度估计值,预测铝尘肺的发病趋势,预期尚存健康人数和患病剂量,我们对该厂铝尘肺的患病情况进行了调查。现用寿命表法分析如下。 To investigate the dose-response relationship between aluminum-containing dust and aluminum pneumoconiosis in Baotou Aluminum Plant, the allowable concentration of this kind of dust was estimated, the trend of occurrence of aluminum pneumoconiosis was predicted, and the number of remaining healthy and the expected sickness were expected. The prevalence of illness was investigated. The current life table method is as follows.
