A PRELIMINARY STUDY OF THE DISTRIBUTION OF PHOSPHORUS AND SILICON COMPOUNDS IN TASIK KENYIR, HULU TERENGGANU, MALAYSIA

Abstract

A preliminary study of phosphorus and silicon compounds in lake water was conducted at the Tasik Kenyir, Terengganu, Malaysia. Monthly water samples were taken from August to October 2010. In general, higher concentrations of both nutrients were recorded at the western part of the lake. The results also showed that the nutrient concentrations were lower compared with other selected study areas. According to the National Water Quality Standards (NWQS) classifcation for Malaysia, the concentrations of dissolved inorganic phosphorus and silicon were in Class I, indicating a natural level which is suitable for the conservation of the natural environment, water supply without any treatment, and fishery activities.
