Abstract:

为比较北京城区与远郊区大气颗粒物中水溶性无机离子的组成特征,2012年4月,利用Andersen分级撞击式采样器同时在2个采样点进行大气颗粒物分级采样,样品采用离子色谱分析.结果表明,城区和上甸子大气颗粒物中水溶性无机离子总浓度分别为(83.7±48.9)μg·m-3和(75.5±52.9)μg·m-3,NO3-、SO42-和NH4+是最主要的水溶性无机离子,分别占总离子浓度的81.2%和84.2%.粒径分布显示,Mg2+和Ca2+在5.8—9.0μm的粒径范围出现峰值,Na+、NH4+、Cl-在0.43—1.1μm和4.7—9.0μm的粒径范围出现双峰,K+、NO3-和SO42-在0.65—2.1μm的粒径范围出现峰值.后向轨迹簇分析表明,气团来自南方时,城区和上甸子二次离子浓度分别为(92.4±40.0)μg·m-3和(95.0±35.4)μg·m-3,来自其他方向时,分别为(24.0±10.8)μg·m-3和(13.3±10.6)μg·m-3.
