Abstract
Green mussel (Perna viridis) is a favorite seafood, which has good protein content and economical price. The shellfish habitat is in a polluted area in the Jakarta Bay caused by industrial waste. Presently, the consumption of green mussels is very problematic because the habitat of green mussels has experienced pollution. Bioaccumulation of heavy metal study was conducted to determine the process of heavy metal accumulation in a biota by using a certain dosage. The heavy metal cadmium was used to be exposed to a biota as much as half LC50 is 0.1 ppm. The depuration process was performed to reduce the levels of cadmium metal in green mussel. A seven-day drainage depuration method was used by immersing acetic acid and citric acid with variations of concentration 0.75 %, 1.5 %, and 2.25 % in 24, 48, 72, 96, 120 min variations. Levels of cadmium in green mussel were measured using atomic absorption spectrophotometry. Concentration of cadmium decreased to 3.05 mg.Kg−1, 1.7 mg.Kg−1 and 0.65 mg.Kg−1 after depuration process that used immersing by water, acetic acid and citric acid, respectively.
