Abstract

Heavy metals pollution in sediments is a major concern, yet limited information is available about the distribution of heavy metals in the sediments of the western Basin of Lake Erie. Four sampling sites in the Western Basin of Lake Erie were selected for this study, according to historical input in the basin, and core sediment samples were collected. A sequential extraction procedure was utilized to determine the concentrations of As, Cd, Co, Cr, Cu, Ni, Pb and Zn as (1) adsorbed on surface of sediments, (2) bound to organic matter, and (3) bound to Fe-Mn oxides. The total concentrations of metals were compared with the allowable regulatory limits, for fresh water sediments, to assess the extent of contamination at these locations. Some remediation techniques have been reviewed to evaluate the possibility and the applicability of these techniques in the water environment. Selection of the most suitable remediation technique is a site-specific decision, which requires a multi-stage study as well as laboratory treatability tests in order to achieve the required degree of remediation.
