Abstract
Heavy metals in the mangrove sediments of Chuuk and Kosrae, Federated States of Micronesia were analyzed to examine the pollution levels of heavy metals using enrichment factor (EF) and pollution load index (PLI). The mean concentrations of Cr, Ni, Cu, Zn, As, Cd and Pb in surface mangrove sediments were 642, 125, 46.9, 149, 15.6, 0.14 and 8.55 μg, respectively. Kosrae mangrove sediments showed the highest concentrations of Cr and Ni while Chuuk contains more of other metals such as Cu, Zn, As, Cd and Pb. Compared to those from other mangrove regions of the world, Cr, Ni and As levels in mangrove sediments from Micronesia were at higher levels whereas Cu, Zn, Cd and Pb were at lower to median levels. In core sediment of Chuuk, metal concentrations in the upper part were higher than those in the lower part. Based on the EF and PLI values, As is evaluated as the heaviest contaminant in the surface sediment from Micronesia whilst other metals (Cr, Ni, Cu, Zn, Cd and Pb) are present at slightly lesser levels.
