abstract:
The concentrations of Cu, Zn, Pb, Cd have been determined in bottom sediments of Syczyńskie, Sumin and Rotcze lakes located in the Łęczna-Włodawa Lakeland, eastern Poland. There was observed differentiation of heavy metals content in the bottom sediments of studied lakes. The heavy metals concentrations decreased in order Zn>Pb>Cu>Cd. The average Cu, Cd, Zn contents were relatively low. Only Pb occured in higher concentration than the accepted toxic levels for macrophytes. The degree of concentration of heavy metals in lakes Sumin and Rotcze correspond in general to the content of organic matter.
