Analysis of Pb Levels as Pollutant in the Waters of the Sentani Lake, Jayapura-Indonesia: Study of Determining Water Quality

Author(s): Auldry F Walukouw

We have conducted environment research on the waters and analysis of metal levels of lead (Pb), in the Sentani lake in Jayapura, Papua Province-Indonesia. Sediment characteristics and metal content analysis have been analyzed to determine the levels of Pb in the waters. Metal level analysis using Atomic Absorption Spectrophotometry instrumentation. Waters characteristics that have been analysis are density-porosity, water content, texture, pH, DO, and others. The results showed that at each sampling site and every waters depth showed highly significant influence on the metal content of Pb. Average content of metals, Pb, in sediments at each location were location 1 at 28 mg/kg, location 2 of 4 mg/kg. Concentration of Pb (4 to 28 mg/kg) and in waters is lower than the standard quality of heavy metals in waters is 40 mg/kg for Pb level, therefore concentrations of Pb in sediments at two locations of Sentani lake is still below the quality standard so that the levels of Pb in the waters is not contaminated. The existence of Sentani lake waters act as a reservoir heavy metal and not as a source of pollutants to the water quality in the Sentani lake. A routine check on water at Sentani lake needed to ensure the produced parameters did not exceeded the Ministry of Health Regulation.
