Abstract

This investigation was conducted to determine metals contamination from anthropogenic sources in sediments of Klang Estuary. Surface sediments from Klang Estuary were analyzed for metals (Cd, Zn, Ni, Cu, Pb and Fe), organic carbon and particles sizes. Quality assessment of sediments was evaluated using modified degree of contamination (mCd) and pollution load index (PLI). A comparison was also made with sediment quality guideline values. The present study showed that highest concentrations of metals were found in stations with high anthropogenic discharge. The mCd and PLI suggested that degree of metals contamination in surface sediments could be classified as “low to moderate degree of contamination.” With the rapid economic development and urbanization around the Klang Estuary, ongoing monitoring studies on heavy metals contamination should focus on contaminant sources within the estuary.
