TRXRF ANALYTICAL EVALUATION OF HEAVY METALS IN THE MALAYSIAN BRACKISH BIVALVE, GELOINA CEYLONICA (LAMARCK)
用TRXRF分析法测试马来西亚微咸水中双壳类软体动物Geloina ceylonica(Lamarck)中的重金属

The trend in aquaculture of bivalves in Malaysia appears to be intensified extending-from the bloody cockles, Anadara granoss L., mussels, Perna viridis L., and possibly to consider a brackish water bivalve species, Geloina ceylonica(Lamarck). Lately, the natural resource of this species is depleting and is attributed to industrial pollutants in the aquatic ecosystem. Analysis of shellfish meat of Geloina ceylonica from mangrove swamp areas of Sungei Puyu, Butterworth, P.W., Malaysia, employing the latest technique of Total Reflection X-ray Fluorescence Activation Analysis indicated that the toxicity effects of such metals, i.e. As, Ba, Br, Cd, Co, Cr, Cu, Fe, Ga, Hg, Mn, Ni, Pb, Rb, Se, Sr, Ti, V and Y are negligeable. Hence, this warrants indepth studies from various approaches to restock the freshwater shellfish species natural resource which is high in nutritive values.
