Sediment Quality Assessment: Chemical and Biological Approachesnsfer of chemicals from sediments to organisms is now considered to be a major route of exposure for many species. These issues are focusing attention on sediment contamination and highlight the fact that sediments are an important resource (Adams et al. 1992).

Interaction of Pesticides with River Sediments and Characterization of Organic Matter of the Sedimention in the liquid phase of natural waters will be low compared to the particulate phase. The chemicals can be sorbed on the sediments as well as on the suspended matter (colloids). A short review about the concentration of typical organic pollutants in sediments is given by Förstner (1989). The mec

Ecotoxicity of Certain Heavy Metals Affecting Bacteria-Mediated Biogeochemical Pathways in Sedimentss have had to cope with elevated concentrations of non-essential and toxic heavy metals. As a result, effective mechanisms of resistance to heavy metal ions have evolved (Beveridge 1989). Ecotoxicity of heavy metals via the main biogeochemical pathways of assimilation and dissimilation of carbon in

Bioassays on Sediment Toxicitys for both sediments and water ecosystems. The different approaches currently applied in such environmental impact assessment programs appear to vary. The presently practised approaches to conserve aquatic sediment quality need to be re-evaluated in order to establish a uniform and meaningful criter

Trace Element Diagenesis in Polluted Sediments of the River Elbe Estuaryticulate matter which is transported into the sediment by flocculation and sedimentation (Irmer et al. 1985). During high water discharge and storm events trace metals are remobilized from the sediments into the river water by the resuspension of particles (Wilken et al. 1991). In addition to this e
