Abstract: Abstract The relationship between gonadal development and the concentrations of four heavy metals Mn, Zn, Fe and Hg in the tissues of the clam Galatea paradoxa was evaluated at the Volta estuary, Ghana, over an 18-month period. Metal concentrations in the clam tissues were highly variable over the sampling period and seemed to be influenced by the reproductive cycle of the clam. Mn concentrations varied over a wide range from 49 to 867 lg/g and exhibited a significant positive correlation with gonadal development (p = 0.0146, r2 = 0.3190). Zn and Fe concentrations ranged from 13 to 59 lg/g and 79 to 484 lg/g, respectively and both revealed negative relationships between gonad development and metal accumulation (Zn (p = 0.0554, r2 = 0.0554) and Fe (p = 0.1040, r2 = 0.1567)). Hg concentrations ranged from 0.026 to 0.059 lg/g over the sampling period and exhibited a slight positive relationship between gonadal development and metal accumulation (p = 0.0861, r2 = 0.1730).
