ABSTRACT

A study on the bioaccumulation behaviour of four trace essential metals (Cu, Fe, Mn and Zn) by the freshwater snails, Turritella sp. collected from three rivers in Danum Valley Forest Conservation area and Sarawak was carried out. The concentrations (µg g^-1) of Cu, Fe, Mn and Zn determined in the whole body of the snails was 31.6-63.1, 368.7-741.4, 107.6-926.7 and 119.9-716.4, respectively. This study has shown that under natural environment, Turritella sp. is capable of bioaccumulates trace essential metals, especially Zn and Cu. The results have shown that Turritella sp. can accumulate Cu and Zn up to 1-2 times higher than that determined in sediments. The accumulation behaviour was strongly dependent on the amount of trace metals in the sediment and this indicated that ingestion may be the main route to the uptake of these essential metals. Most of the trace essential metals were accumulated in the viscera, followed by soft tissue and snail shell.
