Study of water and sediment surface quality on defilement of heavy metals Pb & Cd at a downstream section of Musi River, South Sumatera, Indonesia

This research (1) analyzed the content of Pb and Cd in water sediment; (2) physical chemical parameters water; (3) determined enrichment factor accumulation index sediments; (4) to identified quality based on Pollution Index (IP) STORET. The analysis was carried out using PCA (Principal Component Analysis) Pearson's correlation, conducted downstream section Musi River, Palembang, a random sampling technique. Based analysis, it found that waters had surpassed standard whereas contents both heavy metals sediment still met standard. It also several variables did not meet criteria. Enrichment Factor (EF) Accumulation (Igeo) Cd, river been defiled. pollution values IP STORET indicated heavily polluted. PCA, three factors which affected were found.
