| Abstract: | The availability of heavy metals in contaminated sediment evaluated for beneficial reuse, before and after chemical amendment, was evaluated using poultry manure as the amendment. The dredged sediment was only slightly contaminated with heavy metals. Availability tests on the amended sediment showed an increase in heavy metals, most likely because of poultry feed amendments passed to the manure. There would be difficulty finding one chemical amendment to reduce the availability of a number of heavy metals because the metals exhibit different chemical properties. © 2001 John Wiley & Sons, Inc. |
