Exchange processes in estuaries such as the Westerschelde, an overview
Duursma, E.K.; Merks, A.G.A.; Nieuwenhuize, J. (1988). Exchange processes in estuaries such as the Westerschelde, an overview. Hydrobiol. Bull. 22(1): 7-20. dx.doi.org/10.1007/BF02256777
A short overview is presented on the principles of exchange processes of metals and PCBs for the Westerschelde, the estuary between the river Schelde and the North Sea. Critical reference is made to the commonly used interpretation of concentration-salinity mixing curves of dissolved material, and to the application of stability and distribution constants (coefficients) for metal species partitioning between dissolved, complexed and solid phases. A discussion is given on the specific PCB congener distribution, the impact of Kds on the solid/liquid percentual distribution in an estuarine system and the approach to determining the residence times of substances in an estuary.
