ABSTRACT
The aim of this study was to analyze the heavy metals transport in a river-reservoir system. Sediment
samples from 25 locations (9 from the Powa River and 16 from the Stare Miasto Reservoir) were analyzed
for trace metals contents (Cr, Ni, Cu, Zn, Cd, and Pb). The relationships between heavy metal concentrations
and bottom sediment physical properties were determined with the use of the multivariate statistical
techniques cluster analysis (CA), principal component analysis (PCA), and canonical correspondence
analysis (CCA). The results showed that concentrations of heavy metals in the sediments of the reservoir
were higher than those in the bottom sediments of the river. Concentrations of heavy metals in bottom
sediments in the river above the reservoir were characterized by lower spatial variability. Decisive influence
on heavy metal concentrations of bottom sediments had silt, clay, and total organic matter content.
