SHORT-RANGE TRANSPORT OF AEROSOLS EMITTED BY A POINT SOURCE OF MIXED CHARACTER AT PÁLHÁZA, HUNGARY

Longitudinal distribution of ground level aerosol concentrations have been measured in the neighbourhood of an emission source of mixed character by the PIXE method. The source was located in a valley in hilly terrain. The elements observed are divided into two groups according to the magnitude of the fine-to-coarse concentration ratio. The elements of small ratios are crust-related elements and the concentration of these elements show strong decrease with transport distance. The elements of large ratios are oil-related elements and the concentration are relatively stable during short-range transport.
