摘要
对常州市城市扬尘、煤烟尘、机动车尾气尘、建筑水泥尘、钢铁冶炼尘等主要PM_(2.5)排放源进行采样、分析,建立相应的化学成分谱数据库。分别利用等离子体原子发射光谱法、离子色谱法和光热分析法对其进行其化学组分分析,确定各类PM_(2.5)排放源的化学组分特征和标识元素。研究初步建立了常州市大气PM_(2.5)主要排放源的化学成分谱,结果表明,常州市城市扬尘、煤烟尘、机动车尾气尘、建筑水泥尘、钢铁冶炼尘的标识元素分别为Si,Al,OC,Ca,Fe。
PM_（2.5） from urban fugitive dust, coal dust, motor vehicle exhaust dust, construction dust and steel dust of Changzhou were sampled and analyzed. Then relevant source profiles are constructed. According to their chemical composition analysis,characteristics and marker elements of these PM_（2.5） sources are acquired. The chemical composition of the main emission sources of PM_（2.5） in Changzhou city was preliminarily established in this study. The results indicated that markers of urban fugitive dust, coal dust, motor vehicle exhaust dust, construction dust and steel dust are Si, Al, OC, Ca, and Fe respectively.
