Abstract: An assessment of marine contamination due to heavy metals was made in the mangrove areas based on marine bivalves and sediment collected in Tok Bali, Kelantan during 30 August 2007. Sediment samples were analyzed for sedimentological characteristic, heavy metals, and organic carbon. Whereas, the marine bivalves were analyzed for heavy metals contents. Concentrations of Mn, Cu, Zn and Sr were ty pically high in sediments compared to the bivalve. The average concentration of Cr, Mn, Cu, Zn, Sr, Ba and Pb in sediment is 83.7 67 µg/g, 139.400µg/g, 1 l.450µg/g, 82.9 12µg/g, 45.17 0µg/g, 3 l.473µg/g and 35.087 µg/g. The average concentration of Cr, Mn, Cu, Zn, Sr, Ba and Pb in bivalve is 2.1 42µg/g, 47.845 µg/g, 4.67 0µg/g, 79.97 6µg/g, 34.380µg/g, l.423µg/g, and l.606µg/g. The percentage of organic carbon in station 1, station 2, station 3, station 4, station 5 and station 6 is 1.08%, 0.81 %, 0. 84%, 0.93%, 1.31 % and 0.89% respectively. Result on normalization showed that all the studied elements (Cr, Mn, Cu, Zn, Sr, Ba and Pb) were derived from natural sources or terrigenous origin.
