EV-94-10 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science, School of Environment, Resources & Development Thesis (M.Sc.) - Asian Institute of Technology,1994 Apportionment of aerosol pollution sources was completed by two Target Transformation Factor Analysis (TTF A) programs for Beijing urban area. The two programs are TTF A with test vectors compiled by MATHCAD software and TTFA with unique vectors compiled by QUICK BASIC 4.5. It was possible to find out major aerosol pollution sources using these two programs. The data used in this study were mainly collected from Beijing Municipal Institute of Environmental Protection Science. The results from TTF A with test vectors show that soil plus coal burning, building material and petroleum are major aerosol pollution sources, which account respectively for 70%, 9%, 14% of Total Suspended Particles (TSP with diameter<lOOæm). The· program of TTF A with unique vector only identified tree or four pollution sources. The results are consistent with the structure of Beijing's energy consumption. In this study, aerosol pollution source investigation has been successfully integrated with factor analysis to explore a strategy of aerosol pollution control. Aerosols Su, W.
