KONTAMINASI LOGAM BERAT PADA IKAN BUDIDAYA DALAM KERAMBA JARING APUNG DI WADUK CIRATA

Abstract

Cirata lake is often used to throw garbage and wasted water (domestic, industrial andagricultural waste). It is causing pollution. One of the pollution subtances is heavy metallike mercury (Hg), plumbum (Pb), Cromium (Cr) and cadmium (Cd). Heavy metalpollution will create negative effect on living organism. Heavy metals may becomecarcinogenic, mutagenic and teratogenic agent. The aim of this research is to evaluateheavy metals in fish that were cultured in pan culture in Cirata Lake. The research wereconducted in three steps, i.e. to determine water quality (physical and chemicalparameters), to determine heavy metals pollution and to determine heavy metalscontamination in fishes were cultured in pan cultured, especially in gill, liver, lymph andmeat. The result of the research revealed that water quality in Cirata Lake was goodenough category, but that lake was polluted by heavy metals (Pb, Cd and Hg). Thecultured fishes in pan cultured (Cyprinus carpio and Oreochromis niliticus) were highcontaminated by heavy metals, especially in gill, liver and lymph; but heavy metalscontamination on meat is lower than gill, liver and lymph. The meat of cultured fishes inpan cultured in Cirata Lake is relatively being safe for consumption.
