Correlations among inorganic and organic elements in particulate matter (pm_10) in urban area of venezia-mestre

摘要

Concentrations of inhalable particulate matter(PM_10)Pb Zn Pt Ce Cd Se and of Benzo(a) pyrene (BaP) were determined in three locations near Venice from September 2000 to September 2001 Meteorological conditions were considered during the sampling winter except for Cd and Se in the two sites at Mestre.Spatial adn temporal variations were observed.There were correlations between Pb and Zn and PM_10 Cd and Se Pband BaP adn in the main street sampling site also between BaP and Pt.Therir possible sources of emission are discussed on the basis of correlations among elements.
