摘　　要：为研究三明市市区大气颗粒物污染情况,采集市区内典型区域的大气颗粒物样品,然后进行分析检测,并采用化学质量平衡受体模型(CMB模型)进行源解析研究.研究结果表明,三明市市区大气颗粒物污染中TSP指标较好,PM_(10)的达标情况偏差,且"三钢"和"三化"是市区内大气颗粒物污染的主要排放来源,其排放的煤烟尘和冶金尘为三明市市区大气颗粒物污染的主要源类.To investigate the pollution of atmospheric particulates in Sanming downtown area,the samples of atmospheric particulates was collected from representative region in urban area and put into analysis,in which chemical mass balance receptor model was adopted to the conduction of source apportionment. The results showed that the TSP index of the pollution caused by atmospheric particulates was better than that of PM10 and it should be noted that Sangang and Sanhua were the main emissions of the atmospheric particulates. The soot of coal combustion and metallurgical engineering which were released by the above two constituted the main source class of the particle pollution in urban area.
