摘要
应用受体模式的化学质量平衡法 (CMB) ,对南京市城区 7个环境监测点环境空气中的总悬浮颗粒物 (TSP)进行污染源的源解析 ,得出 4类主要污染源对TSP的平均贡献率 :建筑尘 39 8% ,煤烟尘 2 5 7% ,土壤尘 1 9 2 % ,冶炼尘1 8%。同时 ,对该市城区的地面尘也进行了源解析 ,结果表明地面尘与环境空气中TSP的构成相近。
The pollution source of TSP in urban atmosphere of Nanjing from seven environmental monitoring sites were analyzed by the chemical mass balance method (CMB) based on receptor model. The average contribution of four pollution sources to TSP were that: building dust was 39.8%, coal smoke dust was 25.7%, soil dust was 19.2%, smelting dust was 1.8%. The source of land surface dust was also researched, and is constitution was as same as TSP in atmosphere.
