Abstract

Concentrations of hexachlorocyclohexane were determined in Cameron Highlands Catchment, Malaysia. A total of 96 surface water and sediment samples at eight sites were collected along the rivers in dry and wet seasons of 2011. Concentrations of total HCHs in surface water and sediment ranged from "not detect" to 25.029 ng/L and from 0.002 to 59.124 ng/g dry weight respectively. However, those in the Bertam River were approximately higher than Telom River. The spatial distribution of HCHs revealed the obvious historical usage and new inputs of these pesticides. Among alpha, beta, gamma and delta isomers, gamma was the most dominant compound in the sediment and water as well. Furthermore, results reflect different contamination patterns among sampling seasons. Hardly, it can find a good correlation between the concentration of HCHs in sediment and water samples. The results provide important information on the current contamination status in the one of key aquaculture area in Malaysia and it emphasizes the importance of cease using persistent agrochemicals such as lindane.
