Oxygen Demand of the Sediment from the Semariang Batu River, Malaysia
The Semariang Batu River is located near the city of Kuching, with residential and shrimp farming activities which may impact the quality of the sediment. However, sediment of this river had not been investigated. Therefore, the objectives of this study were to determine the sediment oxygen demand (...
