An aerosol sampling campaign has been carried out in the town of La Spezia, Italy, from 10th to 31th March 1999, using two-stage continuous streaker samplers that provide, in conjunction with proper IBA techniques, a hourly resolution of aerosol concentration and the separation of the particulate matter in two fractions. Particulate analysis was performed by PIXE at the INFN Van de Graaff accelerator of the University of Florence extracting hourly concentrations for elements from Na to Pb, The total particulate concentration in the two fractions has been determined as well by an optical analysis of the deposition. The statistical analysis of the concentration time series obtained by PIXE and by optical scanning of the streaker frames is presented. The contribution of some pollution source to the local aerosol composition is also discussed.

Abstract
An aerosol sampling campaign has been carried out in the town of La Spezia, Italy, from 10th to 31th March 1999, using two-stage continuous streaker samplers that provide, in conjunction with proper IBA techniques, a hourly resolution of aerosol concentration and the separation of the particulate matter in two fractions. Particulate analysis was performed by PIXE at the INFN Van de Graaff accelerator of the University of Florence extracting hourly concentrations for elements from Na to Pb, The total particulate concentration in the two fractions has been determined as well by an optical analysis of the deposition. The statistical analysis of the concentration time series obtained by PIXE and by optical scanning of the streaker frames is presented. The contribution of some pollution source to the local aerosol composition is also discussed.
