“…Data curah hujan bulanan (Tahun 1991(Tahun -2013 alihan 1 (premonsoon). George (1993);McComb et al (2014) mengemukkan adanya pola musiman yang unik dimana konsentrasi logam berat tertinggi ditemukan selama musim hujan dan konsentrasi terendah ditemukan saat musim peralihan (premoonson). Hal ini diduga karena adanya masukan yang berasal dari run off daratan sekitar selama musim hujan (Mitra, 1998;McComb et al, 2014).…”

Selain dari daratan, atmospheric deposition yang terjadi di udara kemudian terdeposisi di tanah dan perairan, dapat berkontribusi terhadap peningkatan konsentrasi logam berat di estuaria (USEPA, 2006).…”

The Musi River is one of the biggest river of twelve big rivers in South Sumatra ABSTRAKSungai Musi merupakan satu diantara dua belas sungai besar di Provinsi Sumatera Selatan. Kualitas air sungai Musi ini mempengaruhi kualitas air perairan di muara sungai dan kehidupan disekitarnya untuk itu perlu diteliti konsetrasi Cu dan Pb. Tujuan penelitian ini adalah mengetahui distribusi logam berat Cu dan Pb dan status mutu perairan pada bulan Maret dan September 2014. Sampel air dan sedimen dikumpulkan dari delapan stasiun penelitian yang tersebar di Sungai Musi bagin hilir hingga muara. Logam berat Pb dan Cu dianalisis menggunakan metode USEPA 30050B dan diukur menggunakan AAS jenis varian spektra plus dengan menggunakan flame campuran udara -asetilen. Konsentrasi Cu dan Pb terlarut pada bulan Maret berturut-turut adalah 0,002 -0,006 mg/l dan 0,002-0,003 mg/l, bulan September adalah 0,001-0,010 mg/l Cu dan 0,001-0,005 mg/l Pb. Konsentrasi Cu dan Pb dalam sedimen pada bulan Maret berturut-turut adalah 6,92-16,4 mg/l dan 1,9-11,4 mg/l, pada bulan September 2,3-13,9 mg/l Cu dan 4,29-9,95 mg/l Pb. Hasil pengujian dengan uji-T menunjukkan bahwa konsentrasi Pb dan Cu (terlarut dan sedimen) pada bulan Maret dan September tidak berbeda nyata. Secara keseluruhan, konsentrasi logam berat Cu dan Pb di Sungai Musi bagian hilir masih dibawah beberapa baku mutu yang ditetapkan.

“…Terrestrial heavy metals are usually washed into the aquatic ecosystem through industrial and municipal runoffs and therefore, makes estuaries and coastal ecosystems the major recipient and accumulators of aquatic pollutant (McComb et al, 2014). Human activities such as oil and gas exploration, boat fabrication and maintenance and other industrial activities have also led to the input of these elements into the ecosystem (Freije, 2015;Turner, 2014;Turner and Rees, 2016).…”

This study evaluates the levels of Pb, Cd, Cr and Ni and the potential ability of water hyacinth (Eichhornia crassipes) plant to bioaccumulate these metals in Woji Creek, Rivers State, Nigeria by collecting water and water hyacinth samples along a 1.3 km stretch of the creek between 2018 and 2019 for analysis. Water samples and plants were collected from five stations across the creek from June to October of both years. The trend of metal concentration in the surface water is Pb > Cr > Ni > Cd in 2018 and Pb > Ni > Cr > Cd in 2019. In 2018, metal concentration in the root are in the order: Cr > Ni > Pb > Cd, while the trend for the shoot is Cr > Pb > Ni > Cd. In 2019, Cd was detected in the roots ranging from 1.009 ± 0.001 to 9.545 ± 0.006, while Pb ranged from 0.298 ± 0.006 mg/kg to 121.006 ± 0.005 mg/kg. There was substantial bioaccumulation of Pb, Ni and Cr in the roots with most plant roots having BCF > 1. In the shoot, BCF was > 1 for Pb and Cr only, while Ni had BCF < 1. The findings from this research also assert that the E. crassipes can be used in the application of rhizofiltration as phytoremediation technique in Woji creek.

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
