Abstract
Seven sampling stations surrounding Banding Island, Temenggor Lake were chosen to
evaluate the status ofTemenggor Lake's sediment quality. A total set ofsediment samples from each
station were collected during December 2010. An experimental technique was involved to analyze
the sediment particle size (sand, silt and clay), pH, conductivity, total organic carbon, total organic
matter, total hydrocarbon and some selected metals. The texture analysis study revealed that the
sandy type sediment was the predominant fractions in Temenggor Lake. In this study, chemical
characteristic of the sediment in Temenggor Lake has shown total organic carbon (0.07- 0.62%),
organic matter (0.20- 1.83%) and hydrocarbon (0.01 - 0.39%). Metals concentrations in lake
sediment were found to be in the following order Fe > Mn > Pb > Cr > Zn > Cu > Cd. All metal
studied in Temenggor Lake were generally low and in the range of natural concentration when
compared with Interim Sediment Quality Guidelines (ISQG). It was also noted that the Mohd Shah
Resort Station is a predominant potential to be polluted compared to other sampling locations.
