肺中的粉尘含量和肺的病理学变化的关系,是了解引起工人临床疾病的空气污染物的组成和数量的基础。 关于死亡的煤矿工人肺中粉尘含量及其与放射学、病理学和生理学研究的关系的报告已有许多。相反,有关硬岩石矿工肺中粉尘含量或其他有相似环境接触的职业团体(如对翻砂工人)的研究还很少。 仅在安大略有机会研究吸入矽尘后的作用,因为在这里所有接触矽尘的工人每年进行一次X线胸片检查的惯例已有多年了。现在,每年还进行一次呼吸功能检测。本文报告了8名已故的硬岩石矿工尸检肺中粉尘含量与放射 The relationship between the amount of dust in the lungs and the pathology of the lungs is the basis for understanding the composition and amount of air pollutants that cause clinical disease in workers. There have been many reports on the dust content of lungs in coal miners who died and their relationship with radiological, pathological and physiological studies. In contrast, there is very little research into the dust content in the lungs of hard rock miners or other occupational groups that have similar environmental exposure, such as flip-flops. It is only in Ontario that there is an opportunity to study the effects of inhalation of silica dust since it has been a practice for all workers exposed to silica dust to perform annual X-ray examination here for many years. Now, there is an annual respiratory function test. This article reports the autopsy of the dust content and radiation in eight of the late hard rock miners
