摘要: 利用2014年和2015年春节期间南京市城区与郊区主要污染物(PM10、PM2.5、SO2和NO2)浓度监测资料和气象观测资料,分析了禁燃烟花爆竹对南京市空气质量的影响。结果表明:2015年春节期间禁燃烟花爆竹对南京市空气质量改善显著。2015年春节期间,南京市AQI同比2014年春节期间下降了20%-30%,除夕至正月初三期间空气质量为优良;同时,SO2和NO2质量浓度变化幅度较小且均达到空气质量二级标准;PM10和PM2.5质量浓度变化趋势与2014年春节期间相反,且变化幅度比SO2和NO2质量浓度大,变化幅度分别为13.0-234.5 μg·m-3和17.5-320.4 μg·m-3。PM10和PM2.5是造成南京市春节期间空气质量污染的主要污染物,其中PM2.5所占比重较大,但2015年春节期间PM10和PM2.5最高小时浓度分别占2014年春节期间的51.0%、40.0%。此外,2015年春节期间南京市城区与郊区PM2.5浓度比2014年春节期间均降低且差异较小。春节期间气象因素对南京市污染物扩散具有较大影响,但禁燃烟花爆竹对PM2.5浓度的降低起决定性作用。

Abstract: Based on monitoring data of main pollutant (PM10,PM2.5,SO2,and NO2) concentrations and meteorological data from urban and suburban areas in Nanjing during the Spring Festival of 2014 and 2015,the effects of fireworks forbidden on air quality were analyzed.The results indicate that fireworks forbidden during the Spring Festival of 2015 result in improving air quality effectively in Nanjing.Air quality index (AQI) decreases 20%-30% during the Spring Festival of 2015,comparing to that during the same period in 2014.Air quality remains in a good level from New Year's Eve to January 3,2015 according to the lunar calendar.During the Spring Festival of 2015,SO2 and NO2 concentrations vary relatively small and reach the secondary level according to Chinese air quality standard.However,PM10 and PM2.5 concentrations show an opposite variation with those in 2014 and have relatively larger range of variation,varying from 13 μg·m-3 to 234.5 μg·m-3 and from 17.5 μg·m-3 to 320.4 μg·m-3,respectively.The main pollutants that cause air pollution during the Spring Festival in Nanjing are primarily PM2.5,and then PM10.The maximum hourly mean concentrations of PM10 and PM2.5 during the Spring Festival of 2015 only take up 51% and 40% to that of 2014,respectively.In addition,PM2.5 concentrations in urban and suburban areas reduce obviously in the Spring Festival of 2015,but the difference between the two areas is small.Meteorological factors greatly influence pollutant diffusion during the Spring Festival in Nanjing;however,the fireworks prohibition has a dominant effect on the reduction of PM2.5 concentration.
