Abstract
At the beginning of August 1997, 72 samples of flood sediments were taken along the Upper and Middle Odra river and its tributaries. The concentrations of Zn, Pb, Cu, Cd, Co, Ni, Cr, Mn, and Fe in the bulk samples and in the <20 mu m fraction were determined by AAS method. The contents of metals vary in wide ranges and are significantly higher in the <20 mu m fraction of sediments. The range concentrations vary as following: Zn 274...3 656 mg/kg, Pb 79...1 773 mg/kg, Cd 1.7...11.8 mg/kg, Cu 38...2 244 mg/kg, Cr 14...384 mg/kg, Co 4...73 mg/kg, Hg 0.2...3.9 mg/kg, Mn 214...6 972 mg/kg, and Fe 1.5...16.3%. The highest amount of; the metals was found in the Wroclaw and Glogow regions. The mobile (exchangeable and carbonatic fractions) portions of metals reached up to 50% of Zn, 40% of Pb and Cu and 60% of Mn.
