Abstract基于颗粒物化学组分监测仪(Aerosol Chemical Speciation Monitor, ACSM)的在线实时观测,对北京春季亚微米气溶胶(PM_1)的化学组分和特性进行分析,并利用PMF & ME-2 (Positive Matrix Factorization & Multilinear Engine)源解析模式对其中的有机物进行来源解析。结果表明,在观测期间PM_1的浓度变化范围为2.40-249.10 μg·m~(-3),平均浓度58.0 μg·m~(-3),其中有机物为主要组分,占比41.4%。有机物的来源包括四个一次源:机动车排放源(hydrocarbon-like organic aerosol, HOA)、烹饪源(cooking organic aerosol,COA)、燃煤燃烧源(coal combustion organic aerosol,CCOA)、生物质燃烧源(biomass burning organic aerosol, BBOA)和一个二次有机源(oxygenated organic aerosol,OOA)。通过不同污染事件的对比结果表明,二次气溶胶在重污染期所占比重会明显上升,并且静稳气象条件也对污染的形成产生重要影响。
