A health study was conducted in three communities in the greater Montreal region; the first two were characterized by relatively high particulate and sulfur dioxide levels, respectively, and a third community without major industrial pollution. In each community, 300 men and women 45 to 64 yr of age were studied. Residents of the two more polluted communities exhibited a higher prevalence of respiratory symptoms and mean lung function evaluated by various tests was lower than in residents of the less polluted community. When intercity differences in age and smoking were accounted for, no statistically significant intercity differences in health status could be shown. Given the limitations of this study, the results provide no evidence to suggest that current Canadian standards for sulfur dioxide adequately protect human health as measured by the indices used in the study, for adults in the age range of 45 to 64 yr.
在大蒙特利尔地区的三个社区开展了一项健康研究；前两个社区分别以较高的颗粒物和二氧化硫水平为特征，第三个社区没有 major industrial pollution。在每个社区，研究了300名45至64岁的男性和女性。两个污染更严重社区的居民出现呼吸道症状的患病率更高，通过各种测试评估的平均肺功能低于污染较轻社区的居民。当考虑到城市间年龄和吸烟差异时，未发现城市间健康状况存在统计学上的显著差异。鉴于本研究的局限性，研究结果没有证据表明，就本研究中使用的指标而言，加拿大现行的二氧化硫标准能充分保护45至64岁成年人的健康。
