Vertical profile of selected heavy metals (Al, Ba, Ca, Cr, Fe, K,Mg, Na, Pb and Zn) was<br />

determined. The objectives of this study are to determine the vertical profile of<br />

selected heavy metals in core sediment from Kelantan waters and to assess the<br />

pollution status of core sediment from Kelantan waters. This study was carried out by<br />

using Teflon Bomb acid digestion method and analysed using ICP- OES. The<br />

concentration of selected heavy metals can be arranged in decreasing order as follows,<br />

Ba > Cr > Zn > Pb > Al > Ca > Fe > K > Na > Mg. Pearson’ correlation and elemental<br />

ratio suggest that metals are derived from anthropogenic sources. Enrichment factor<br />

shows extreme severe enrichment of Ca but PLI value indicates that the sediment is<br />

not polluted. This study is important as a baseline study and provide reliable<br />

information about pollution status in Kelantan waters.<br />
