||This study tested the hypothesis that mercury, cadmium and chromium become bound to or within the exopolymers of aquatic microbial biofilms, where they can be concentrated to the extent that they block or retard oyster settlement. Mercuric chloride, methyl mercury chloride, cadmium chloride and potassium chromate were used to test .
