Determination of heavy metal in water, sediment and fishes in the Rajang River at Pelagus area
In this study, Pelagus area in Rajang River was studied to determine its heavy metal pollution level. Water, sediment, and fish samples were collected from upstream to downstream of the river at Pelagus area. All the samples were prepared by acid digestion and analyzed for Al, Cu, Fe, Mn, Ni and Zn...

In this study, Pelagus area in Rajang River was studied to determine its heavy metal pollution level. Water, sediment, and fish samples were collected from upstream to downstream of the river at Pelagus area. All the samples were prepared by acid digestion and analyzed for Al, Cu, Fe, Mn, Ni and Zn by Atomic Absorption Spectrometer while the Hg concentration was measured by Mercury Analyzer. For water, the mean concentration of studied metals was decreased in an order Fe > Al > Mn > Ni > Zn > Hg. The concentration of Fe was the only one that over the limit of drinking water standard level. Zn, Ni and Hg refused to show significant differences (pÈ0.05) between the mean concentrations for all the sampling stations. All the selected metals were successfully detected in sediment. Sediment present in decreasing order as follows Al > Fe > Mn > Zn > Ni > Cu > Hg. The results of the three types of the assessment of sediment contamination status (CF, lgeo, PLI) indicated that the sediment is under low contamination and unpolluted condition. All the mean concentrations of study metals showed significant variation (p<0.05) with the sampling stations. The highest wet weight concentration of Al, Fe, Hg, Ni and Zn were present in P. micronemus, B. schwanenfeldii, M. wyckill, C. armatus and R.borneensis respectively.
