哈尔滨道路附近大气可吸入颗粒物浓度及其成份分析
Concentration and Composition Analyzing of Atmospheric Inhalable Particles near the Road in Harbin
【摘要】 采集了2005年8月具有代表性的道路附近空气中可吸入颗粒物(PM10),分析了PM10中的离子、重金属及碳成分含量。结果表明,哈尔滨市道路附近PM10离子组分中SO42-、NH4+、Ca2+浓度较高,其主要来源于交通尘污染;富集因子法表明元素Cr、Zn和Pb来源于人为污染;EC/TC大于0.36,主要来自于汽车尾气等一次污染源的排放。
【Abstract】 PM10 in atmosphere was sampled in August 2005 near the roads of Harbin.The contents of ions,heavy metals and carbon ingredients of PM10 were analyzed.The results showed that concentrations of SO2-4,NH+4,Ca2+ were higher,their main pollution sources came from traffic dust.Enrichment factor indicted that Cr,Zn and Pb were from man-made pollution.EC/TC>0.36 indicted carbonaceous contents mainly came from primary particulate pollution emissions,such as motor vehicles.
