摘    要:根据南京城区草场门与远郊固城湖大气观测点PM2.5质量浓度及组分监测结果,分析了2012年春节期间烟花爆竹燃放对城市气溶胶细粒子的影响。结果表明,春节除夕和初五烟花爆竹集中燃放时段,草场门观测点PM10和PM2.5均出现同步异常突升,且细颗粒物占比较大,PM2.5最大峰值同比远郊固城湖观测点分别高出2.79倍和6.02倍;PM2.5各化学组分中,城区草场门观测点水溶性离子K^+、Cl^-和SO4^2+以及微量元素K、Al、Mg、Fe、Ba等值同比远郊固城湖明显偏高,春节烟花爆竹燃放对南京城区空气质量影响显著。

关 键 词:燃放烟花爆竹  细颗粒物  化学组分  南京

Abstract:The study analysed the effect of firecracker setting-off on the fine particle pollution in city during the Spring Festival, based on the data of the mass concentration and the component of PM25 on Caochangmen(CCM) monitoring station in urban Nanjing and Guchenghu(GCH) monitoring station in suburb Nanjing. The results indicated that, during the firecracker setting-off on the New Year's Eve and the 5th of Jan. In the lunar calendar period, the mass concentration of PM2.5 rose abnormally on CCM station, and its actually hourly maximum concentration were 2.79 and 6.02 times higher than the concentration on GCH station. The concentration of water-soluble ions ( K^+、Cl^- , SO4^2 +) and the elements ( K, A1, Mg, Fe, Ba) of PM2.5 on CCM station were higher than the concentration on GCH station. As a result, the firecracker setting-off can dramatically affect the air quality in urban Nanjing during the Spring Festival.
