Abstract:
The concentration of more than 25 trace elements have been determined in total air particulate matter and in the size segregated fractions from the
urban area of Pavia (North Italy). The PM10 fraction was also collected and analyzed. A study of the solubility in water and in physiological
solution of the trace elements contained in the PM10 was also carried out. The resulting solutions were further submitted to column
chromatography using Chelex 100 to perform a preliminary chemical characterization. INAA was used as the main analytical technique. ET-AAS
was used for all Pb and Cd measurements and, in some cases, for the analysis of V, Mn, Cu and Ni.
