摘要：The Musi River is one of the biggest river of twelve big rivers in South Sumatra Province. Water quality of this river affects the water quality in the estuary and biological health in its surrounding so that it is important to determine the Cu and Pb concentrations. The purposes of this study were to analize distribution of heavy metals (Cu and Pb) and to determine the water quality status in March and September 2014. The water and sediment samples were collected from eight stations along the Musi River from downstream to the estuary. Heavy metal concentration was analized by employing USEPA 30050B method using AAS Spektra plus variant with air mixure flame – acetylene. Dissolved Cu and Pb concentrations in March were 0,002 - 0,006 mg/l and 0,002-0,003 mg/l, respectively, while in September were 0,001-0,010 mg/l for Cu and 0,001-0,005 mg/l for Pb . Cu and Pb concentrations in sediment detected in March were 6,92-16,4 mg/l and 1,9-11,4 mg/l, respectively, while in September were 2,3-13,9 mg/l for Cu and 4,29-9,95 mg/l for Pb. Student test analysis showed that was no significant differences between Pb and Cu concentrations (dissolved and sediment) between March and September. Generally, the concentration of heavy metals Cu and Pb in Musi River estuary were still below specified quality standards.
