本文通过收集资料和现场调查的形式，以成都市污染程度不同的两区为对比，分析了硫酸盐化速率与呼吸道疾病的动态变化关系。结果发现硫酸盐化速率与呼吸道疾病的发生呈明显正相关，尤以高浓度污染区更明显；且硫氧化物对慢性呼吸道疾病的影响比对急性呼吸道疾病的影响更加敏感、更密切相关。
This paper compares the two areas with different levels of pollution in Chengdu by collecting data and field surveys, and analyzes the relationship between the rate of sulfation and the dynamic changes of respiratory diseases. The results showed that the sulfation rate was positively correlated with the occurrence of respiratory diseases, especially in high-contamination areas. The effects of sulfur oxides on chronic respiratory diseases were more sensitive and closely related to the effects of acute respiratory diseases.
