| Abstract: | The secondary ion mass spectrometry method (ToF-SIMS) has been applied to the analysis of some mineral and organic species
on the surface layers of airborne urban particulates. Particulate matter was collected on aluminum sheets of the 8-stage Anderson
type cascade impactor from three different sampling sites in the city of Lodz, Poland, which were different in terms of aerosol
source apportionment. The obtained results show that vehicle combustion products occur mainly in fine fraction with aerodynamic
diameters below 1μm. The main contribution to the mineral components comes from direct and traffic related soil resuspension.
