Abstract

A 150 cm core sediment from the mangrove forests of Kuantan, Malaysia were analyzed for Pb, U, Zn and Mn using Inductively Coupled Plasma Mass Spectrometry (ICPMS). Generally, heavy metal concentrations recorded in this study were below levels found in polluted estuaries, even though some relatively high concentrations of metals were observed at several depths. In this study, Pb, U and Zn have an enrichment values (EF) significantly greater than unity and may therefore be considered to have some influenced from the anthropogenic input whereas Mn which have EF values about unity are considered to be predominantly terigenous in origin.
