摘要
The paper calculates and analyzes physical and chemical characteristics of total suspended particles(TSP),including mass concentration,absorption coefficient,optical refraction index imaginary unit and chemical composition based on observational data of atmosphere aerosol in Xi'an and Nanjing from 1997 to 1999.Enrichment characteristic of TSP elements and sources of pollution are discussed via statistical treatment of enrichment factor of elements and correlation analysis.The result shows that aerosol particles exist remarkable differences in physical and chemical.The highest enrichment in TSP is Pb,Zn,S and As,which comes from different kinds of pollution.
