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。
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 SO4^2-, NH4^＋ , Ca^2＋ 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.
