Trace Metals in Littoral Sediments from the North East Coast of the Bay of Bengal along the Ship Breaking Area, Chittagong, Bangladesh

Mohammed Ashraful Azam Khan and Yusuf Sharif Ahmed Khan

ABSTRACT

The composition of trace metals (Cd, Cu, Zn, Fe, Mn, Cr and Pb) in the sediments of the intertidal zone of ship breaking area of the north east coast of the Bay of Bengal has been determined using Flame Atomic Absorption Spectrophotometer. The mean values of trace metals are 0.88 μg.g‾1 for Cd, 32.91 μg.g‾1 I for Cu, 33.54 μg.g‾1 for Zn, 5272.13 μg.g‾1 for Fe, 556.10 μg.g‾1 for Mn, 78.09 μg.g‾1 for Cr and 23.18 μg.g‾1 for Pb. The levels of trace metals in the sediments of the study area have been compared with the recommended values unpolluted sediments. Correlations coefficients of different trace metals have ranged between 0.05 to 0.87 and it is observed that Cd is negatively correlated with virtually all the trace metals present. Geoaccumulations of metals indicate that, Cd is the most enriched metal followed by Pb and Cu. This high level of Cd indicates Cd might contaminate the sediments through anthropogenic sources. As per analysis and subsequent determinations, the beach of the ship breaking area has been indicated as polluted zone.
