Abstract
Streaker aerosol samplers allow an hourly time resolution in the particulate elemental concentrations and are a useful tool for studying air pollution in complex urban areas. We have tested this device for collection efficiency and aerodynamic diameter separation. Our evaluations have been based on the simultaneous exposure of two streaker samplers in the same site (equipped. respectively. with one and two substrates) and of a seven stage Battele impactor. Ah the filters and the impaction plates have been analysed by PIXE at the INFN accelerator in the University of Florence, Italy. The size distribution of the more abundant elements and the collection efficiency have been evaluated by comparison among the three samplers.
