Assessment of Trace Metals Distribution in Lake Kenyir, Malaysia

摘要

Measurements of dissolved and particulate trace metals (Cd, Cu, Pb, Fe and Zn) were made on water samples collected from Lake Kenyir, Malaysia. Samples were taken monthly from the same stations during August-October 2010. Comparison with the National Water Quality Standards (NWQS), Malaysia showed that all dissolved trace metals were classified as Class I (clean status) for all surface waters, although some of the trace metals displayed slightly higher concentrations at the eastern part of the lake. No comparison based on NWQS could be made for particulate trace metals as they are not listed in this classification. When comparing with other selected lakes in Malaysia, the trace metals in this study area were among the lowest concentrations.
