Abstract:
Objective To explore the effect of the meteorologic factors on air pollution in the summer in Xian, China. Methods The data of SO2?NO2 and PM10 concentrations in the air and the related meteorologic factors [maximum temperature(tmax), minimum temperature(tmin), average air pressure(P) and relative humidity(H)) from April 1st to June 30th in 2005 were collected. The correlation between the air pollutant level and related meteorologic factors was analyzed by the elements time diagram and multiple regression models with SPSS 11.0 software. Results A significant correlations between the meteorological elements and air pollutants was seen, the regression models for air pollutants were as follows, lnSO2=-3.352+0.019 tmax-0.026 tmin, lnNO2=-3.448-0.003H+0.012 tmax-0.015 tmin and lnPM10=-2.197+0.011 tmax-0.021 tmin. Conclusion The meteorologic factors have some effects on the air pollution levels and then impact human health in some degree.
