A Study of Heavy Metal Accumulation in Sediments at Phuket Bay, Saphan Hin, Phuket Province
Kaimook Jaileak and Pensiri Akkajit
Abstract—The concentrations of heavy metals (Sn, Pb, and Zn) were investigated in two sediment cores at Phuket bay, Phuket, Thailand. The analysis of heavy metal content was carried out by using aqua regia digestion and measured by using inductively coupled plasma optical emission spectrometer (ICP-OES). The concentrations of Sn, Pb, and Zn were ranged from 49.9 to 167 mg kg-1, 9.6 to 58.7 mg kg-1 and 45.4 to 144 mg kg-1, respectively. The degree of pollution in sediments assessed by Geo-accumulation index (Igeo) indicated that the sediment samples in this study were either not contaminated or moderately contaminated with Zn and Pb (-1.40 to 0.26 and -1.24 to 0.97, respectively). In addition, the accumulation of heavy metals was evaluated using Enrichment Factor (EF) and the results showed that sediment samples are minimal to significant enrichment from anthropogenic activity (Pb and Zn: 1.6 to 6.2 and 2.1 to 6.9, respectively).
