The distribution of selected metals in the surface sediment of Langkawi Coast, Malaysia
Surface sediment samples were collected from five stations covering 25 sampling points from the Langkawi coastal waters. Concentration of metals such as Zn, Cu, Pb, Cd, and Cr were determined using an Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The detected concentration range of Zn, C...

| Summary: | Surface sediment samples were collected from five stations covering 25 sampling points
from the Langkawi coastal waters. Concentration of metals such as Zn, Cu, Pb, Cd, and Cr were
determined using an Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The detected
concentration range of Zn, Cu, Pb, Cd, and Cr were 41.02-137.1 μgg-1, 14.36-46.32 μg.g-1, 14.4-
38.6 μg.g-1, 0.6-2.4 μg.g-1, and 40.5-84.5 μg.g-1 dry weight respectively. Enrichment factors (EF)
analysis showed that the source of Zn, Cu and Cr in the sampling areas were predominantly of
terrigenous in origin while the source of Pb and Cd were slightly of anthropogenic in nature. |
