| 摘 要： | 通过采集武汉市土壤风沙尘、建筑水泥尘、城市扬尘、餐饮源、生物质燃烧源、工业煤烟尘和电厂煤烟尘等7类源样品，并分析其碳组分、水溶性离子组分和无机元素组分，建立PM10和PM2.5源成分谱.研究表明，地壳元素Si、Ca、Al以及Fe等是土壤风沙尘的主要特征组分，其中Si是含量最高的成分，也是土壤风沙尘的标识组分.无组织建筑水泥尘中Si和Ca元素含量较高，将Ca元素作为无组织建筑水泥尘区别其他源类的重要元素，而有组织建筑水泥尘中OC、SO42-含量比无组织建筑水泥尘高.城市扬尘中Ca的含量相对较高，表明城市扬尘受到建筑水泥尘影响较多.生物质燃烧源成分谱中OC的含量远高于成分谱中其他组分，另外Cl-和K的平均含量也较高，K一般为生物质源的特征元素.

| Abstract: | PM10 and PM2.5 from soil dust,construction dust,urban fugitive dust,catering sources,biomass combustion sources,industrial coal dust,and power plant coal dust were collected,and their carbon components,water-soluble ion components,and inorganic element components were analyzed to establish their source profiles.Studies have shown that the crustal elements Si,Ca,Al,and Fe are the main characteristic components of soil dust,among which Si is the component with the highest content and is also the marker component of soil dust.The contents of Si and Ca were higher in unorganized construction dust.Ca was regarded as an important element that distinguished unorganized construction dust from other sources,while the contents of OC and SO42- in organized construction dust were higher than those in unorganized construction dust.The content of Ca in urban fugitive dust was relatively high,which indicated that urban fugitive dust was more affected by construction dust.The content of OC in the source profiles of biomass combustion sources was much higher than that of other components in the source profiles.In addition,the average contents of Cl- and K were higher.K was the characteristic element of biomass combustion sources. |
