The samples of the solid aerosol were taken in umava mountains (SFR/FRG frontier) to be analyzed by PIXE or XRF methods in the frame work of air pollution import investigation. To evaluate differences in the results and to minimize discontinuities in the time series, some analyses of the same samples were done by both methods. The peak areas of Al, Si, S, K, Ca, Ti, Cr, Mn, Fe, Cu and Zn were compared to establish the degree of correlation for separate elements. On the basis of the comparison, the multiplicative factors were determined to estimate the XRF peak areas from the PIXE ones. Relative element concentrations and other data were derived from both determined and estimated peak areas and taken into account in the preliminary stage of research.
