ABSTRACT: This research was carried out at two locations, Ada and Aveglo at the Volta Estuary, Ghana to evaluate the importance of sediments as regulatory media in controlling the levels of four metals, Manganese (Mn), Zinc (Zn), Iron (Fe) and Mercury (Hg) in the tissues of the clam, Galatea paradoxa (Born 1778) and to investigate the possible relationships between the concentrations of the metals in the sediments and the clams. The clams were categorized into three size classes as follows: small (25 - 40 mm), medium (41 - 55 mm), and large (above 55 mm). To understand the possible relationships between the concentrations of the studied metals in the sediments and in the tissues of the three clam size classes, the monthly concentrations of the studied metals were graphed and subjected to Pearson correlation analyses (p
