| 摘 要： | 使用β射线测尘仪、EMS污染气体监测系统、安德森9级采样器和IC型离子色谱分析仪对2013年8月10~28日南京市亚青会期间PM2.5、污染气体和水溶性离子进行了观测分析.结果表明,在亚青会期间PM2.5、NO2、O3和CO的浓度分别为37.0、19.3、48.1和0.7×103μg·m-3,分别比亚青会前降低了26.0%、42.6%、36.1%和46.1%.亚青会期间,细粒子段主要水溶性离子为Na+、NH+4、Ca2+和SO2-4,占80.6%;粗粒子段主要水溶性离子为Na+、Ca2+、NO-3和SO2-4,占77.9%.Ca2+、Mg2+和NO-3在亚青会期间为双峰型分布,其余离子为三峰型分布;亚青会前和后水溶性离子均为三峰型分布.由NO-3/SO2-4的值判断亚青会前和后南京市SO2和NOx主要来自于移动源,在亚青会期间主要来自固定源.
