A qualitative and quantitative analysis of atmospheric deposition samples has been carried out by XRF method in Debrecen city over a long period. Seasonal variations in the fluxes of 14 elements such as Si, S, Cl, K, Ca, Ti, Mn, Fe, Cu, Zn, Br, Sr, Zr and Pb have been determined. Ca, Si and S elements had the greatest yearly average flux compared to other elements. The atmospheric deposition of most of the elements have higher values in summer than in winter season. Results are compared with literature data.
