Chemical speciation was used to characterize the environmental conditions of bottom sediment of rivers in the catchment area of the Lake Balaton. The fractionation by a selective sequential leaching process has the advantage of simulating, to a certain extent, the various natural environmental factors. In the study a four step leaching process was applied, and samples were taken in three seasons at 8 sampling points from rivers. The fractions were (1) exchangeable/bound to carbonate, (2) bound to Fe/Mn oxide, (3) bound to organic matter/sulfides, and (4) acid soluble residue. The results, in general, showed that there was no serious metal contamination in the sediment samples.
