我国若干地区总悬浮颗粒物和沉积尘来源解析

使用受体数学模型中的化学元素平衡法（CEB）对西安市的总悬浮颗粒物和市区地面以及北京郊区、湖北黄石工业区、河南平顶山工业区、陕西枣园的积尘进行了来源解析。结果显示几类源中，土壤上贡献是最主要的，其次是煤烟尘和建筑尘，再次是冶炼尘，汽油尘最小。各源贡献出现的地区、季节差别，主要是与工业活动和人们生活使用的材料和燃料相一致。这些结果反映了我国大气颗粒物来源的基本状况，对大气环境防治有指导意义。

SOURCE APPORTIONMENT FOR CHINESE AEROSOL AND ACCUMULATED DUST

Chemical Element Balance(CEB)has been applied to identify sources of total suspend particles, which were from city of Xi'an, and accumulated dusts, which were from suburbs of Xi'an, industrial areas of Huangshi in Hubei province, industrial areas of Pingdingshan in Henan province and city of Zaoyuan in Shanxi province. The contribution of sources to aerosols is soil dusts,coal ash,limestone particles,refined dusts,and petrol dusts.The differences of areas and seasons between contribution of sources to aerosols are consistent with activity of human beings and industrial exhaust. These results reflect the basic condition of China,and have significance of prevention and cure in Atmospheric Environment.
