【摘要】 本文使用受体模型中的化学元素平衡法（ＣＭＢ）对南京市的大气总悬浮颗粒物（ＴＳＰ）来源进行解析研究，同时对地面积尘进行解析。结果表明建筑尘对ＴＳＰ的贡献为３１％～４５％，位列第一，其次是煤烟尘（２０％～３８％），土壤尘（１５％～２３％），冶炼尘（＜３％）。对地面积尘的解析结果也与ＴＳＰ相同。该文的结果为污染物的防治提供决策依据。更多还原

【Abstract】 Chemical Element Balance has been applied to identify sources of total sus- pended particles and accumulated dusts,which were from city of Naming. The results show that 31-45% of the aerosols came from lime.stone,which is the main source, 20-38% from coal ash, 15-23 % from soil dust and 1-2. 5 % from refined dusts. The study of accumulated dusts has the same results. The results have significance of prevention and cure in atmospher- ic environment.更多还原
