Abstract

Source apportionment of CO, SO9, and in urban atmosphere by speciated volatile organic compounds A. Pelliccioni, P. Buttini, A. Latella Eniricerche - Via Ramarini 32, 00016 Monterotondo Scalo, Rome, Italy ABSTRACT Receptor modeling is used to identify the sources that contribute to atmospheric concentration of pollutants in a busy street of Milan (Italy). Eight volatile organic compounds (VOC) were selected by cluster analysis in order to recognize the typical antropogenic sources. These compounds were successively elaborated with Target Trasformation Factor Analysis (TTFA) and Chemical Mass Balance (CMB) to obtain the sources' apportionment. The sources' VOC fingerprints were then used to calculate the emission ratios to primary pollutants (CO, SO,, NOx). This methodology was integrated in an air quality survey network so that hourly contributions were calculated automatically both for VOC and primary pollutants. INTRODUCTION The kn
