目的：调查温州市区冬春季节空气污染物浓度及其与儿童呼吸道疾病的相关性。方法2013年1月—4月,实时记录温州市区空气质量检测数据,收集温州医学院附属第二医院育英儿童医院儿童门﹑急诊患者就诊数据,分析空气污染物与儿童呼吸道疾病的相关性。结果调查期间温州市区PM2.5﹑ PM10﹑ NO2的平均浓度值均处于较高水平； CO的平均浓度较低,空气污染物浓度在二月份最低。 NO2浓度与总门诊量及儿童呼吸道感染关系最为密切,根据回归分析, NO2浓度每上升10μg/m3,门诊总量可能增加3.5%左右,上呼吸道感染增加4%左右,下呼吸道增加8%左右。 PM2.5与哮喘急性发作密切相关, PM2.5浓度每增高10μg/m3,哮喘急性发作病例可能增加10%。结论温州市区冬春季节首要污染物为PM2.5, PM10及NO2的浓度也严重超标。 PM2.5浓度变化与儿童哮喘急性发作相关性最大,对儿童呼吸道感染影响最大的可能是NO2。

Objective To investigate the levels of different air pollutants in Wenzhou city in winter-spring season, and determine their relationship with airway diseases in childhood. Methods During January and April, 2013, the live air quality data from Wenzhou city were obtained, and the data from visits to the pediatric outpatient and emergency department in the Second Affiliated Hospital & Yuying Children’s Hospital of Wenzhou Medical University were also collected. The correlation analysis was performed to investigate the relationship between air pollutant levels and respiratory diseases. Results During the study period, the average concentrations of PM2.5, PM10 and NO2 stayed in high level, and the level of CO was lower. The levels of air pollutants were lowest in February. Correlation analysis indicated that NO2 had the closest relationship with airway infection. Regression analysis revealed that 10 μg/m3 increase of NO2 might result in 3.5%increase of total outpatient visit quantity, 4%increase of upper airway infection and 8%lower airway infection. PM2.5 closely related to acute exacerbation of asthma. An increase of 10 μg/m3 of PM2.5 might result in 10%increase of clinic visits due to acute asthma attack. Conclusion PM2.5 is a major pollutant in Wenzhou city in winter-spring season, and the concentration of PM10 and NO2 are also much higher than acceptable level. The change of PM2.5 has the closest relationship with acute asthma attack, and NO2 might be the most important risk factor for airway infection.
