太原市PM_(10)与SO_2空气污染对儿童肺功能的影响

Study on the Effect of PM_(10) and SO_2 Air Pollution on Children's Pulmonary Function in Taiyuan City,China

[目的 ]探讨太原市空气PM10 和SO2 污染对儿童肺功能的影响。 [方法 ]应用Dockery公式计算PM10 和SO2个体接触量EPM1 0 、ESO2 。应用多元线性回归分析个体接触量EPM1 0 、ESO2 与儿童肺功能指标间的相关性。 [结果 ]在采暖期ESO2 在 0 .0 995～ 0 .5 83 5mg/m3 范围波动时 ,均与五项肺功能指标显著相关 ;在非采暖期 ,EPM1 0 在 0 .13 2 4～ 0 .42 14mg/m3 的范围波动 ,均与 4项肺功能指标显著相关。性别分析显示 ,女性儿童的肺功能与PM10 和SO2 显著相关。 [结论 ]太原市的空气污染已对儿童肺功能 ,特别是对女性儿童肺功能造成一定的影响 ,采暖期儿童肺功能显著降低。提示今后太原市应注重PM10 和SO2

Objective] To study the association between the air pollution of PM 10 and SO 2 and childrens pulmonary function. [Methods] EPM 10 and ESO 2 (PM 10 and SO 2 exposure dosage) were calculated according to Dockerys formula,and the association between the air pollution of PM 10 and SO 2 and childrens pulmonary function was analysed by using multiple linear regression. [Results] When ESO 2 ranges from 0.099 5 to 0.583 5 mg/m 3,the correlation between ESO 2 and all indicators of childrens pulmonary function is significant in the heating period. In the non heating period,however,when EPM 10 varies from 0.132 4 to 0.421 4 mg/m 3,it correlated with 4 of 5 indicators significantly. Compared male with female children,the results suggested that female childrens pulmonary function was affected more significantly. [Conclusion] The air pollution has affected childrens pulmonary function,especially female childrens pulmonary function in Taiyuan city. In the heating period,childrens pulmonary function decreased significantly. Therefore,countermeasures should be taken so as to bring PM 10 and SO 2 air pollution under control.
