Heavy metal speciation and mineralogy in sediment off Pahang coast, Malaysia during pre-and post north east monsoon seasons

Abstract

Twenty six surface sediment samples were collected from the near-shore area of Pahang coast, South China Sea during the pre- and post- Northeast monsoon periods. The concentrations of Cr, Fe, Mn, Ni, Pb and Zn of five chemical fractions in the sediment were determined using the fractionation scheme of Tessier et al. (1979). The mean concentrations of total metals studied were considered low compared to cmstal value and regional studies.
