本研究选择上海市区飘尘污染轻，而二氧化硫污染程度不同的三个地区，通过准历史性前瞻的流行病学调查方法，采用多因素回归分析探讨二氧化硫对人体呼吸道慢性疾病发生的影响。结果表明大气二氧化硫污染与慢性咽炎和慢性支气管炎的发生有关，大气二氧化硫浓度每增加６０μｇ／ｍ３，上述疾病发生的优势比为１．３８和１．３２。
In this study, we selected three regions with light dust pollution and different levels of sulfur dioxide pollution in Shanghai, and used multivariate regression analysis to investigate the influence of sulfur dioxide on chronic respiratory diseases in China through quasi-historic prospective epidemiological investigation. The results showed that the atmospheric sulfur dioxide pollution was related to the occurrence of chronic pharyngitis and chronic bronchitis. For each 60 μg / m3 increase of atmospheric sulfur dioxide, the odds ratios for the above diseases were 1.38 and 1.32.
