Abstract
The article presents the results of research on concentrations of heavy metals (Cd, Cr, Cu, Ni, Pb and
Zn) in fluvial sediment samples collected in the flood plains of the Odra River. The samples were collected from
the presently flooded area and from the area which was formerly flooded. The extraction of sediment samples
was conducted using aqua regia and four other extractants: 0.01M CaCl2, 0.1M HCl, 0.005M DTPA and 0.02M
EDTA. The analysis of the results revealed different concentration values for particular sample collection sites
situated along the course of the Odra River. The differentiation of metal concentrations in the investigated samples
depending on the extractants was also observed. The concentrations of metals were determined using the
technique of atomic absorption spectrometry with flame atomization (F-AAS).
