INDUSTRIAL SPATIAL DISTRIBUTION AND HEAVY METAL CONCENTRATION OF RIVER WATER IN PALEMBANG CITYSYNTIA RAHUTAMI, M. SAID, EDDY IBRAHIM AND HERPANDI
Water is very important for human life, especially drinking water. River is a water resource that is used to supply drinking water for households and residences. There are several activities and industries in the Musi River, Komering River, Ogan River and Keramasan River. These various activities have the potential to contribute to pollutants such as heavy metals. The industries located along the river in the city of Palembang are The Crumb Rubber Industry, PT. Pertamina, PT. Pusri, PT. Bukit Asam and PT. Semen Baturaja as well as fabric coloring. Some activities that have the risk of producing liquid waste containing heavy metals are coal mining industry and dyeing fabrics. Several parameters that exceed the quality standard are temperature, turbidity, water color, pH, and organics (KMnO4). Heavy metals concentration is still in accordance with the required quality standards. Sediment serves as an absorber as well as a source of heavy metals. Heavy metals in sediments can be lost or re-suspended to cause secondary pollution in water bodies. Accumulation of heavy metals in sediments directly affects organisms. Therefore, it is very important to study the accumulation of heavy metals in sediments and organisms such as shellfish.
