Contamination of the natural environment by metallic elements is an overall issue. The<br />

aims of this study were to estimate concentration of metallic elements in sediment<br />

during dry and wet season and to determine the pollution level in Sungai Setiu. The<br />

selected metallic elements (As, Cr, Cu, Pb and Zn) were detected by Inductively<br />

Coupled Plasma Mass Spectrometry (ICPMS) had been used to determine the metals<br />

and were undergoes digestion method using Teflon bomb previously. The result in<br />

this study showed that the concentration of Cr is higher during dry season compared<br />

to wet season while As, Cu, Pb and Zn enriched. The PLI mean value for wet season<br />

and dry season were 0.698 and 0.882 respectively which showed that Sungai Setiu<br />

surficial sediment are in unpolluted condition. The outcome of this study show the<br />

status of Sungai Setiu which has been exposed to contaminants.<br />
