长期的工业生产和独特的地理气候条件使兰州市成为我国大气污染较为严重的城市之一。本研究于2009年12月冬季采暖期在兰州市内4个城区和榆中县(位于兰州市郊区)进行了TSP采样
测定了样品TSP含量
为进一步研究TSP样品的成分
对样品进行了PIXE分析
得到了TSP样品的元素浓度。关键词总悬浮颗粒物
重金属元素
质子荧光分析
Because of the unique geographic environment and climatic conditions in Lanzhou in northwest China
and its long-time petrochemical and metallurgical industrial activities
it has become a seriously air-polluted city
especially in winter.Winter aerosol samples were collected in four urban areas in Lanzhou and Yuzhong County(located in outskirts of Lanzhou).Their TSP contents were measured
and heavy metal elemental concentrations were analyzed by PIXE analysis.The results were discussed.
