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.
