太原市大气总悬浮颗粒物来源的鉴别

Identification on the source of atmospheric partile in Taiyuan

作者测定了太原市大气总悬浮颗粒物（ＴＳＰ）中１６种化学元素的含量，用化学元素平衡法对太原市大气总悬浮颗粒物的污染来源进行了鉴别。结果表明，太原市５个主要污染源中，土壤和燃煤对大气总悬浮颗粒物的贡献最大，其次是建筑材料和冶金，汽车燃油贡献最小。

Total suspended particulate(TSP) samples were collected at six sites in Tai Yuan and analyzed for 16 elements. The polluation patterns were interpreted by using chemical element balances(CEBs)for five sources:soil, coal,limestone,metallurgical industry and motor-vehicle emissims. The ressults showed that in five sources, soil and coal made the greatest contribution to the primary TSP. Limestone and metallurgical industry made less pollution than soil did motor-vehicle emissions made the least contribution to the primary TSP.
