Spirometric tests of 3280 Ottawa residents in 1969-71 and 2208 Sudbury residents in 1972-73 showed that the mean ratio of forced vital capacity to forced expiratory volume in 1 second was lower in Sudbury, where sulfur dioxide concentrations in the air tend to be appreciably higher than in Ottawa. This difference was significant for both males and females considered separately, and held true when age and smoking habits were taken into account. The prevalence of symptomatic chronic bronchitis was significantly higher in Sudbury males than in Ottawa males, but no such difference could be detected in females.
1969年至1971年对3280名渥太华居民以及1972年至1973年对2208名萨德伯里居民进行的肺活量测定试验表明,在萨德伯里,用力肺活量与1秒用力呼气量的平均比值较低,而萨德伯里空气中的二氧化硫浓度往往明显高于渥太华。分别考虑男性和女性时,这种差异均具有显著性,并且在考虑年龄和吸烟习惯时也是如此。有症状的慢性支气管炎在萨德伯里男性中的患病率显著高于渥太华男性,但在女性中未检测到这种差异。
