The objectives of this study were to investigate the concentration of Lead (Pb) and Cadmium (Cd) in commercial Donax faba sourced from spatially different coasts and to determine the risk of the selected heavy metals to human health. The spatial differences were represented by the North coast (Gian Beach) and the South coast (Slopeng Beach) of Sumenep Regency, Madura Island, Indonesia. The Pb and Cd concentrations of the clam samples were measured in an Atomic Absorption Spectrometer. The health risk potential from the consumption of D. faba clams was calculated by Total Hazard Quotient by determining the Average Consumers (AC) and the High Consumers (HC). Based on the result of independent t-test, significant differences of Pb and Cd concentrations between the North coast and the South coast of Sumenep (p < 0.05). The highest concentration of Pb and Cd was found in the South coast, 0.796 ± 0.071 mg/g and 0.057 ± 0.009 mg/g, respectively. The calculation of health risk potential showed no health effect from the consumption of D. faba clams for both the AC and the HC, thus safe for human consumption. |
