Abstract
Trace metals are present in, and transported through, aquatic systems both in dissolved and particulate forms. This duality of phase contributes to the complexity in the understanding of their environmental geochemistry. Turekian (1977) stressed the significance of solid particles which, from soils to marine sediments, via rivers and winds, are the vectors of trace metals during the course of their geological migration. The relative mobility of a trace metal depends on its physical form (dissolved versus particulate). Similarily, the physical form, more than the distribution of the dissolved species might be responsible for its toxic or beneficial effect on biota (e.g., filter feeders and seizers will respond predominantly to particulate species).
