Abstract
Chest x rays, smoking histories, and pulmonary function tests were obtained for 171 men employed in the manufacturing of silicon carbide. A lifetime exposure to respirable particulates (organic and inorganic fractions) and sulphur dioxide was estimated for each worker. Chest x ray abnormalities were related to respirable particulates (round opacities) and to age and smoking (linear opacities). Pulmonary function was affected by respirable particulates (FVC) and by sulphur dioxide and smoking (FEV1). Pleural thickening was related to age. No exposures exceeded the relevant standards; we therefore conclude that the current standards do not provide protection against injurious pulmonary effects, at least in this industry.
摘要
对171名从事碳化硅制造工作的男性进行了胸部X光检查、吸烟史调查和肺功能测试。估算了每位工人一生中可吸入颗粒物（有机和无机部分）和二氧化硫的接触量。胸部X光异常与可吸入颗粒物（圆形阴影）、年龄和吸烟（线性阴影）有关。肺功能受可吸入颗粒物（用力肺活量）、二氧化硫和吸烟（第一秒用力呼气量）影响。胸膜增厚与年龄有关。没有任何接触量超过相关标准；因此我们得出结论，现行标准至少在该行业无法预防肺部损伤效应。
