Geochemical partitioning of trace metals in the potential culture-bed of the Marine Bivalve, Anadara granosa
- Univ. of Malaya, Kuala Lumpur (Malaysia)
The relative distribution of trace metals in coastal sediment geochemical phases has received considerable attention as a mean of assessing the degree of trace metal pollution. Metals in the non-residual fraction (exchangeable, carbonate, easily reducible, moderately reducible and organic phases) have been demonstrated to be strongly correlated with tissue-metal concentrations in various benthic organisms. Among these phases, the oxides of manganese (easily reducible phase) and iron (moderately reducible phase) and organic matter have been emphasized as important scavengers of available trace metals. Therefore, these phases are undoubtedly among the criteria that should be considered explicitly when assessing the potential bioavailability of metals. The marine bivalve Anadara granosa is commercially cultured in the tidal mudflats along the western coast of the Peninsular Malaysia. The purpose of this study was to provide an assessment of the geochemical partitioning of trace metals in the sediments collected from a culture-bed of A. granosa. The selected area is thought to receive minimal or restricted impacts of trace metal pollution. The present investigation is of significance as a baseline of information for comparative studies with other aquaculture areas in the region. 15 refs., 3 figs., 2 tabs.
