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.
