Abstract

Data on respiratory symptoms and pulmonary function were obtained for 2736 Portland cement plant workers and 755 controls. Personal dust samples contained a geometric mean concentration of 0.57 mg/m3 for respirable dust and 2.90 mg/m3 for total dust. Cement workers and controls had similar prevalences of symptoms, except that 5.4% of the cement workers had dyspnoea compared with 2.7% of the controls. The mean pulmonary function indices were similar for the two groups. Among cement plant workers, the prevalence of chronic phlegm increased with tenure whereas the prevalence of wheezing increased with both tenure and current dust level. Other symptoms and pulmonary function indices were not significantly related to exposure.

摘要

我们获取了2736名波特兰水泥厂工人和755名对照人员的呼吸道症状及肺功能数据。个人粉尘样本中,可吸入粉尘的几何平均浓度为0.57毫克/立方米,总粉尘的几何平均浓度为2.90毫克/立方米。水泥工人和对照人员的症状患病率相似,不过有5.4%的水泥工人出现呼吸困难,而对照人员中这一比例为2.7%。两组的平均肺功能指标相似。在水泥厂工人中,慢性咳痰的患病率随工作年限增加而上升,而喘息的患病率则随工作年限和当前粉尘水平的增加而上升。其他症状及肺功能指标与接触情况无显著关联。
