Abstract:
The impact of air quality assurance measures on urban air quality is studied by taking the air quality during First Jiangsu Development Summit(Nanjing,May 2017)as an example. According to surface meteorological observations,pollutant mass concentration observations and pollutant emission inventory,the change of air quality is analyzed using time series analysis. According to the pollutant emission inventory of 2012 and the detailed pollution control measures of First Jiangsu Development Summit,the potential changes of pollutant emissions in Nanjing during the summit is estimated,and the result shows:the emissions of PM2.5 and PM10 decrease by 57%~60%,followed by CO(36%),NMVOC(35%),SO2(33%)and NOx(26%); the observed daily mean concentrations of CO,NO2,SO2,PM2.5 and PM10 decrease by 22.5%,30.1%,30.9%,3.94% and 19.0%,but O3 increases by 32.1%; after the summit,the observed daily mean concentrations of the major atmospheric pollutants except O3 increase with no emission control actions. The major atmospheric pollutants except O3 in Nanjing are mitigated effectively by the emission control actions under stable meteorological conditions.
