CONCENTRATION HEAVY METALS (Cu AND Pb) IN MUSI RIVER ESTUARY

Abstract

<jats:p>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/lfor Cu and 0,001-0,005 mg/lfor 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.Keywords: heavy metal, Cu, Pb, the Musi River, estuary</jats:p>

Logam Berat Cd di Sungai Musi Bagian Hilir, Sumatera Selatan

“…Beberapa hasil penelitian sebelumnya menemukan akumulasi beberapa jenis logam berat di kawasan Sungai Musi bagian hilir. Putri et al (2015) menemukan bahwa logam Cu terlarut berkisar antara 0,001-0,010 mg/l dan logam Pb berkisar 0,001-0,005 mg/l. Adapun konsentrasi Cu dalam sedimen berkisar 2,3-16,4 mg/kg dan Pb berkisar 1,9-11,4 mg/kg.…”

Cu AND Pb CONCENTRATIONS IN WATER COLUMN AND PLANKTON OF DOWNSTREAM SECTION OF THE MUSI RIVER

“…Hal ini dibuktikan dengan beberapa penelitian sebelumnya Setiawan et al, 2013) yang menemukan adanya akumulasi logam Cd dan Hg dalam sedimen Sungai Musi bagian hilir. Selain itu, logam Cu dan Pb juga ditemukan terkonsentrasi dalam air dan sedimen di sepanjang aliran Sungai Musi bagian hilir hingga muara (Putri et al, 2015). Hasil penelitian terbaru (Putri et al, 2016) menemukan akumulasi logam Cu dan Pb dalam organ hati, daging dan insang ikan seluang (Rasbora sp) dan ikan belanak (Mugil chepalus) yang hidup di kawasan tersebut.…”
