Abstract
Although sediments generally are considered to provide beneficial effects in terms of water quality movement through the 'sorption' of pollutants from the water column, contaminated sediments also may result in adverse effects. The interactions of both metals and organic contaminants with suspended and bed sediments significantly affects the transport and transformation of these pollutants in streams and lakes. Information about these interactions is important in assessing hazards of pollutant exposure in freshwater systems. In the paper, research into the fate and transport of sediment-associated contaminants is reviewed. An overview of contaminant modeling is provided along with model descriptions of chemical and biological transformation processes. Research on the physical movement of contaminated sediment is presented, including near bed sediment transport and advective-dispersive transport in the water column.
