Concentration, Distribution and Geochemical Speciation of Copper in Surface Sediments of the Straits of Malacca

C.K. Yap, A. Ismail and S.G. Tan

Abstract:
The geochemical partitioning of copper (Cu) in surface sediment of two sampling cruises from the Straits of Malacca have been studied. The results show that the total concentrations of Cu in sediments ranged from 2.48 to 11.95 μg g‾1 and 2.59 to 13.3 μg g‾1 for the first and second sampling cruises, respectively. Nonresistant fractions (EFLE, acid-reducible and oxidisable-organic) covered 60.43% (first cruise) and 46.21% (second cruise) of total Cu concentration in the sediments. This indicated that although the total Cu concentration in sediments were relatively low, the geochemical study revealed that about 50% of the total Cu found in the sediment could be due to anthropogenic inputs besides natural origins. Among this nonresistant fractions, the oxidisable-organic fraction contributed about 81-86%.
