The possibility of using a two step method of identifying and quantifying air pollution emissions in an urban environment was examined in this paper. The procedure uses a numerical model called Target Transformation Factor Analysis (TTFA) to estimate source emission profiles using ambient trace element air concentration data. The profiles estimated by TTFA are then employed in a Chemical Mass Balance (CMB) source apportionment analysis for an air shed. The results show that TTFA can be used to provide quantitative estimates of air pollution source profiles for an urban center in China. TTFA can identify source categories of airborne pollution for specific locations, as well as give quantitative data on the composition of the emissions from those source types. Including source profiles estimated by TTFA in a chemical mass balance analysis provides a comprehensive source apportionment methodology which can help researchers more accurately characterize the air pollution source types that pose the greatest concern to human health.
