Aerosol samples were daily taken simultaneously on Nuclepore filters in suburban Budapest and at the regional background air pollution station (K-puszta) 80 km far from Budapest. The samples were analysed among other elements for V, Cr, Co, Ni, Cu, Zn, As and Pb by means of PIXE method. The cases with constant air mass flow between the source and the receptor determined on the basis of radiosonde observation for 925 hPa level carried out in Budapest and Szeged were chosen for modeling consideration. K-puszta station is located between these two cities. A simple source-receptor model of Lagrangian-type was used for the simulations. Budapest was considered as an area source for the elements mentioned above. Aerosol concentration data measured in suburban Budapest were applied as input parameters altogether with the actual mixing heights, precipitation intensities, dry deposition velocities and washout ratios. It was assumed that there are no anthropogenic sources between the two points - except for Pb where road transport has been taken into consideration. Dry and wet cases were separately examined. The aerosol concentrations computed for K-puszta were compared to the data measured there.
