Abstract: Fifteen soil profiles were selected from agricultural areas in Zitny ostrov, and sixty one samples were analysed for their total contents of several trace elements, viz. Ag, As, B, Ba, Be, Cd, Co, Cr, Cu, Ga, Hg, Ni, Pb, Sn, Sr, V, Zn, and Zr. In addition, other soil characteristics have also been determined, viz. particle size, organic carbon, carbonate, cation exchange capacity, and pH. The relations of trace elements with these characteristics were studied using statistical multivariate analysis. Generally, most of the trace elements show strong association with the clays and particularly the organic matter. Consequently, they exhibits strong positive correlation with the cation exchange capacity. They also show strong inter-element relationships which reflect their common occurrence in the clays and organic matter. Sr alone occurs in the carbonate fraction, and Zr in the sand fraction. Vertical distribution of all studied parameters within the soil profiles also proves these conclusions.
