Therefore, our main
objectives were (1) to investigate the effects of the major
physicochemical soil properties on the sorption of Cu(II)
and Zn(II), (2) to provide a more detailed understanding of
the sorption mechanisms between typical agricultural soils

and selected metals, and (3) to provide knowledge in order
to reduce the risk of contamination of the soils in this
region. Furthermore, the results of the detailed analysis of
the parameters involved in sorption processes will be
useful for other soils with similar physicochemical characteristics
in other regions of the world.
