Description: Das Projekt "PRE-ENVPROT 3C, Comparative Studies on Heavy Metal Pollution in Selected Regions of European Seas" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Forschungszentrum Jülich GmbH.Objective: Assessment of levels, fate, behaviour and mass balance of toxic trace metals in coastal and estuarine ecosystems. General Information: Applying suitable Volta metric methods the speciation of dissolved toxic trace metals, particularly Cd, by the chelation with dissolved organic material (DOM) will be clarified under sea water and estuarine water conditions taking into account he decreasing salinity gradient. Particularly the contribution of humic and fulvic material to metal speciation will be assessed. In collaboration with the delta-institute, Yerseke, (Netherlands), the levels, fate, behaviour and mass balance of trace metals in the ooster-and wester scheldt estuary will be studied taking into account seasonal and tidal influences. The atmospheric metal input by precipitation will be measured as well. Additionally, the uptake of Cd and Hg and other toxic metals from soil by certain types of salt marsh plants will be measured to complete an ongoing study which is included in the Dutch delta plan. Already started research on the content, fate, behaviour and mass balance of trace metals in estuaries and coastal waters of the ligurian and tyrrhenian coast will be continued, including a study on the toxic metal burden on risk groups, e.g. fishermen. Also here the trace metal input from the atmoshere with precipitation will be determined.
