abstract:
The research was aimed at evaluating the total contents of copper and its fractions in soils situated on a moraine slope in Siedlce Upland. Sequential fractionation was carried out according to the Zeien and Brümmer method. The speciation analyses indicate that the metal was bound to different parts of the soils’ solid phase. The highest copper content was found in the residual fraction (F7) in mother rock, and the lowest in the easily soluble (F1) and exchangeable (F2) fractions. In soils of transect A and B the correlation coefficients demonstrated that the amounts of copper in separated fractions showed a significant correlation with the total content of copper, fraction of clay, sorption capacity, organic carbon content and organic fraction (F4).
