摘要
为观察北京市空气污染对居民健康的影响，本研究在北京市四个城区选择５６４名儿童为研究对象，进行了肺功能测定和问卷调查。用多元回归分析建立模型后，以残差值为统计量分析。结果显示，西城区和石景山区儿童的大、小气道功能均有不同程度的下降，西城区儿童的ＣＶ和ＭＶＶ及石景山区儿童的ＭＶＶ显著低于海淀区，且肺功能的下降与大气中ＴＳＰ和ＮＯｘ有相关关系，而与ＳＯ２关系较小。西城区资料分析显示，室内燃煤可能与儿童小气道功能下降有关；燃气，特别是天然气可能与儿童大气道功能较低有关。结果表明北京市大气污染已对儿童的肺功能产生一定的影响。
This paper present the association between the air pollution and the pulmonary function of populations.We observed 564 pupils aged 9～11 in the four primary schools of districts in Beijing respectively. ANOVA were showed a significant different on the levels of VC and MVV between the four districts(P<0.05).The pulmonary function was decreased by the higher level of air pollution. The results of residual analysis on FEV1,MVV,MMFF,and the ratio of FEV1 /FVC were showed there were significant different between the coal and natural gas burning,the risk factors were TSP and NOx,and there was a weakly relationship with SO2.Thus,we could see the out or in-door air pollution are harmful for the pupils’pulmonary function.
