摘要: Abstract Spatiotemporal variations of SO2, CO, NO2, O3, PM2.5, and PM10 concentrations their associated sources in three provincial capitals northern China from 2014 to 2015 were examined reveal the association between heating seasons criteria air pollutants. Air pollutant during season significantly higher than those non-heating season, with exception O3. Moreover, without dust storm events was divided into aerosol windstorm respectively. During fossil fuel-based industry motor vehicle emissions respectively account for a major contribution particulate matters gaseous pollutants, Chinese Ambient Quality Standard (CAAQS) attaining rates these pollutants exhibited following order: PM2.5 CO > SO2 > O3. The findings this study are helpful understanding influence anthropogenic natural activities which may improve effectiveness tackling pollution broader way.
