Abstract

Dredging is a necessary procedure to remove unwanted sediments from the seabed. However, the material was disposed back to the sea. Some of the material was contaminated due to industrial waste, sewage runoff and agricultural discharge. Metals is inorganic pollutant which is undegradable and can be toxic to marine ecosystem. The aim of this study is to determine the metal concentration in the material and evaluate the degree of the contamination. Four dredged marine sediments samples were retrieved from Malaysian waters. X-ray fluoresnce was used to determine the metal concentration and contamination indices were used to evaluate the degree of contaminant of the material. There were six metals detected by x-ray fluorescene; As, Cr, Cu, Pb, Ni and Zn. Based on the contamination degree, all the dredged marine sediments were found to be considerably low degree contamination.
