The contaminated sediment serves as a long-term source of toxic elements, since that
mobility and transport in the environment of these elements are strongly influenced to
associated solid phase. In this study, the modified Tessier sequential extraction procedure
was applied for the fractionation of Cd, As, Hg, Cu, Zn, Cr, Pb, Ni and V in the sediments
(Tisa River and canal sediments-Danube alluvial formation), to obtain an overall
classification of trace element pollution in these areas through its spatial distribution …
