    ANALISIS KANDUNGAN LOGAM BERAT Cd, Pb, DAN Mn PADA SEDIMEN KOLAM TPA MUARA FAJAR PEKANBARU
    (2014-03-27) Panjaitan, H.; Bali, S.; Hanifah, T. A.
    The concentration of three heavy metals (Cd, Pb, and Mn) had been known in TPA ponds sediment Muara Fajar Pekanbaru. Pond sediment samples were taken of four TPA ponds in pre-monsoon season (June 7, 2013) and brought to laboratorium for analyzing. Determination of the concentration of heavy metal Pb and Cd was done using Atomic Absorption Spectrophotometry, and determination of the concentration of heavy metals Mn was performed by Persulfat Kolorimetri. Results of heavy metal analysis in the TPA ponds sediment are as follows: Cd: 0-0,0003 mg/g; Pb: 0,0104-0,0150 mg/g; and Mn: 0,3077-0,8928 mg/g. To assess metal contamination in the TPA ponds sediment, USEPA (United Stated Enviromental Protection Agency) guidelines were applied. Based on the guidelines, TPA ponds sediment was unpolluted of heavy metal Cd and Pb. Metal that potential as pollutant is Mn in every TPA ponds. In general all TPA ponds sediment have been polluted and need to be investigated further
