Abstract
The summertime composition of particulate matter in the atmosphere of some Italian towns (Florence, Genoa and Milan) has been studied by means of Ion Beam Analysis (IBA) techniques. The aerosol has been collected simultaneously by two-stage continuous streaker samplers, which separate and collect the PM10 particulate matter in two fractions. The hourly concentrations in air of about 20 elements have been extracted in the fine and coarse fractions of PM10 by Particle Induced X-ray (and Gamma-ray) Emission, PIXE (and PIGE) analysis. Absolute Principal Component Factor Analysis (APCFA) has been used to obtain the apportionment of the sources of particulate matter.
