PENDUGAAN TINGKAT KONTAMINASI LOGAM BERAT PB, CD DAN CR PADA AIR DAN SEDIMEN DI PERAIRAN SEGARA ANAKAN, CILACAP
ABSTRACT: A study was carried
out to investigate the concentrations and contamination levels of heavy metals
in the sediments of Segara Anakan, Cilacap 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 assessment of sediments pollution by heavy
metal was carried out using Contamination Factor (CF), Enrichment Factor (EF)
by comparing to CCME, ANZECC and NOAA targets for sediment quality Guidelines.
The results of this simple comparison revealed that, the Segara Anakan 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) 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 in sediment were
1.50, 18.8, dan 5.7 indicating deficiency to low enrichment for Pb
anrophogenically, and significant enrichment for Cd and Cr. According to the CF
and EF value, Segara Anakan may face a severe heavy metal pollution
contamination problem in the future.
