Water, suspended and bottom sediment samples in the western part of the Dutch Wadden Sea have been analyzed for their metal content (Cu, Zn, Mn, Fe). For sediment samples the total amount, the exchangeable and leachable (according to Chester and Hughes) fractions of these metals were determined. For suspended samples only the leachable fraction was determined. 0.1 N HCl appeared to be the most preferable leaching agent to determine the leachable fraction. It caused 5% clay mineral lattice breakdown. The levels of metals in water show a non-conservative character. The levels of metals in suspended matter cannot be explained by particle size differences (fraction<16µm according to De Groot).
