| Abstract | A study was carried out to investigate the concentrations and contamination levels of heavy metals in the sediments of Segara Anakan, Cilacap ÃÂ for three heavy metals (Cd, Pb, and Cr). sediments samples were collected from six sites during February 2013. The samples were analyzed to determine their heavy metals, pH and total organic carbon (TOC) content. Environmental assessmentÃÂ of ÃÂ sediments ÃÂ pollution ÃÂ by ÃÂ heavy ÃÂ metal ÃÂ was ÃÂ carried ÃÂ out ÃÂ using Contamination Factor (CF), Enrichment Factor (EF) by comparing to CCME,ÃÂ ÃÂ ANZECC and NOAA targets for sediment quality Guidelines. The results of this simple comparison revealed that, the Segara Anakan ÃÂ sediment concentrations of heavy metals are within the permissible limits of standards for Pb. CF value of Pb, Cd, and Cr (0.86, 10.8, dan 3.3)ÃÂ ÃÂ indicated no contamination for Pb (0.86), very strong contamination for Cd (10.8), and moderately to strong contamination for Cr. Calculated EF of the Pb, Cd, Cr ÃÂ in sediment were 1.50, 18.8, dan 5.7 indicating ÃÂ deficiency to low enrichment ÃÂ for Pb anrophogenically, and significant enrichment for Cd and ÃÂ Cr. According to the CF and EF value, Segara Anakan may face a severe heavy metal pollution contamination problem in the future.Keywords: sediments, contamination, anthropogenic |
