Both natural and anthropogenic activities are responsible for the abundant of heavy
metals in the environment. The objectives of this study are to determine the
concentration of heavy metal in core sediment and to assess the environment sources
of sediment based on the establish metal indexes. The samples were analyzed by
using Inductively Coupled Plasma- Optical Emission spectrometry (ICP-OES). The
sediments were digested by using Teflon bomb acid digestion. The order of average
elements concentration was arranged in descending order: Mg< K< Na< Fe< Al< Ca<
Co< Pb< As< Zn< Mn. The vertical profile for most elements showed the decreasing
concentration toward the surface except for As, Ca, Ba and Na. The elemental ratios
were greatly showed the origin of sediment from anthropogenic and oceanic sources.
This study is useful to provide more information in the future for heavy metal index
as a sources indicator in marine environment.
