Besides the two groups of exposed workers (building workers and workers of a steel mill), a reference group of age-matched (40--60 years) unexposed workers was studied. They were examined by the same procedures (interrogation by ESC questionnaire, vital capacity, forced expiratory volume in 1 sec residual volume, apnea CO test and steady-state Co test at rest and exercise of 40 W. Results are presented according to age and smoking habits. They are compared with results observed in the two exposed groups, and discussed.
除了两组暴露工人（建筑工人和钢铁厂工人）外，还研究了一组年龄匹配（40 - 60岁）的未暴露工人作为参照组。他们接受了相同的检查程序（通过欧洲呼吸学会问卷进行询问、肺活量、1秒用力呼气量、残气量、静息和40瓦运动时的呼吸暂停一氧化碳测试以及稳态一氧化碳测试）。结果根据年龄和吸烟习惯呈现。将这些结果与在两组暴露组中观察到的结果进行比较并展开讨论。
