In estuaries the decrease in adsorption of dissolved metals to suspended particulate matter is counteracted by more or less simultaneous increases in turbidity, pH and by the formation of new particulate matter. Experiments on the behaviour of cadmium and zinc under artificial estuarine conditions show that the processes in the region of 0–5% chlorinity are most important.
