The different chemical forms of metals in soils have generally-been investigated using sequential extraction procedures, indicating that the chemical form of the metals and soil characteristics largely affect their extractability (1). Because only certain forms of heavy metals are available to plants, one could expect, that extractable and available are the same. The purpose of this study was to assess the relative efficiency of different soil extractants for determining heavy metals in dredged material-soil mixtures and to determine if a single extractant could give a reliable prediction of plant-available Cd, Cu, Pb, Ni, Mn, and Zn.
