摘要
目的探讨深圳市主要大气污染物与儿科呼吸系统疾病住院人数的关系。方法收集深圳市某医院2006年1月1日-2006年12月31日儿科呼吸系统疾病(上呼吸道感染、肺炎)住院人数资料,结合同时期环境监测和气象资料,进行直线相关回归分析,分析大气污染物对儿科呼吸系统疾病住院人数的影响。结果大气中的可吸入颗粒物(PM10)、NO2和O3月浓度与儿童上呼吸道感染住院人数呈正相关(r为0.650,0.820和0.766,P<0.05);大气中的NO2和O3月浓度与儿童肺炎住院人数呈正相关(r为0.719和0.692,P<0.05)。PM10浓度每增加10μg/m3,儿科上呼吸道感染住院人数增加0.135%;NO2浓度每增加10μg/m3,儿科上呼吸道感染和肺炎住院人数分别增加0.254%和1.129%;O3浓度每增加10μg/m3时,儿科上呼吸道感染和肺炎住院人数分别增加0.173%和0.794%。结论深圳市大气污染物PM10、NO2和O3污染对儿童呼吸系统造成一定的损伤,并导致相应疾病住院人数的增加,可能与NO2和O3的关系尤为密切。
Objective To know the relationship between air pollution and the number of pediatric respiratory disease hospitalization in Shenzhen.Methods Based on the data of 2006,concentrations of PM10,NO2 and O3 and the hospitalization of children with upper respiratory tract infection and pneurmonia were analyzed with linear regression.Results There was a significant positive correlation between the levels of PM10,NO2and O3 and the number of children suffering from upper respiratory tract infection with the correlation coefficients of 0.650,0.820 and 0.766（P〈0.05）.There was also a significant positive correlation between the levels of NO2 and O3 and the hospitalization of children suffering from pneumonia with the correlation coefficients of 0.719 and 0.692（P〈0.05）.A 10 μg /m^3 increase in PM10 was associated with a 0.135% increase of hospitalization of upper respiratory tract infection;a 10 μg /m^3 increase in NO2 was associated with 0.254% and 1.129% increases of hospitalization of upper respiratory tract infection and pneumonia.A 10 μg /m^3 increase in O3 was associated with 0.173% and 0.794% increases in upper respiratory tract infection and pneumonia.Conclusion The inerease of PM10,NO2 and O3 pollution could lead to a corresponding increase in the hositalization of children with respiratory diseases.
