ABSTRACT
Pollution problems in aquatic sediments can be quite varied — from the widespread contamination of a coastal bay receiving untreated urban or industrial discharge to the local leakage from underground petroleum tanks or pipelines. The variation of such problems is further expanded by the range of sediment characteristics in which they occur. Sediments particles can be carriers, receptors and sources for contaminants. The effectiveness of these roles is largely related to their adsorptive capacity; governed mainly by particle size, mineralogy and organic matter, as well as site-specific geochemical conditions. Sustainable management requires a source-to-sink system perspective in order to prescribe remedial actions. The relationships between sediment parameters and pollution problems are summarized and then briefly illustrated using the environmental sedimentology of three harbors: Bergen (Norway), Gothenburg (Sweden), and Ventspils (Latvia).
