INAA in Combination with Other Analytical Techniques in the Study of Urban Aerosol Sources

摘要: Concentrations of elements in fine and coarse PM10 samples collected Ho Chi Minh City were determined by INAA for the purpose characterising air pollution sources using multivariate receptor modeling techniques. Seven common to identified. Resuspended soil dust is dominant accounting 41% particulate mass. In samples, vehicle emissions coal burning are most important about 20% each. Although a great number included input data modeling, interpretation emission was not always straightforward. Information on other source markers needed. Therefore, polarography method used quantifying lead, recently, ion chromatography became available secondary sulphates, nitrates water soluble ions.
