| Abstract: | Characteristic levels of metal ions in post dredged sediment and dredged sediments materials of a municipal creek in the Niger
Delta show that significant concentrations of heavy metals are found to be accumulated more on the surface (0–15cm depth)
of the dredged material as compared to the sub surface (15–30cm) and post dredged sediments. The distribution patterns were
in the following order Fe > Mn > Zn > Cu > Pb > Ni > Cd and Fe > Mn > Zn > Pb > Cu > Ni > Cd for the post dredged sediment
and dredged sediment materials respectively. The levels of the various metals were far below the EPA screening levels for
open water disposal, consequently total levels of heavy metal found in these sediments pose no problem by open-water or upland
disposal |
