摘要 于2013年2月9日—2月16日在南京城区连续观测PM10、PM2.5、PM1的质量浓度、能见度、PM2.5中水溶性离子浓度等参数,探讨了因春节期间烟花爆竹的燃放导致大气中颗粒物浓度出现短时峰值,同时能见度急剧降低,空气质量下降的原因。研究发现:因烟花爆竹的燃放,PM2.5局地短时间浓度可达863μg/m3,能见度仅为1.2km;PM2.5中Cl-、K+与SO2-4浓度短时间上升,这与烟花爆竹中氧化剂、还原剂等组分的燃烧释放有关。由春节期间观测结果统计发现,因烟花爆竹燃放对PM2.5中水溶性离子的贡献约占50%。 Mass concentration, visibility of PM10, PM2.5, PM1, and water-soluble ion concentration of PM2.5 and other parameters have been continuous observed, from February 9 to February 16, in 2013, in Nanjing City. Discussed the reason for the reduction of visibility and decline of air quality while a short term peak appears during the Spring Festival with fireworks. The study found that, due to the discharge of Fireworks, the concentration of PM2.5 reached 863μg/m3 in some area in a short period of time, and the visibility is only 1.2km. At the same time, PM2.5 in Cl-, K+ and SO2-4 rose dramatically in a short time, which to some degree is relating to the release of oxidants, reducing agents and other components in fireworks. Observations during the Spring Festival Statistics found that the contribution of the fireworks discharge to water-soluble ions in PM2.5 is about 50%.
