Abstract

In this study, bioaccumulation and depuration studies of Pb in green mussels were performed. The bioaccumulation process was carried out using flowing water method for 7 days. The Pb ion concentration used was 1.225 ppm. During bioaccumulation, Pb contained in mussels was determined every 24 hours. Two depuration methods were applied in this study, flowing clean water method for 7 days and immersing in acid solution for 2 hours. Two variations of acid solutions used were acetic acid and citric acid with variations concentration of 0.75%; 1.5%; and 2.25%. Pb contained in mussels was analyzed using AAS. The research showed that the highest value of Pb contained was reach after 7 days exposure with concentration of 41.92 mg/kg and concentration factor (CF) value of 32.15 L/kg. The lowest content of Pb was reached after depuration by immersing in 2.25% citric acid for 2 hours. Pb content after depuration was 16.96 mg/kg with the decrease of Pb by 59.5%. Bioaccumulation ability was expressed by Concentration Factor (CF). Based on this experiment, green mussel can be classified as low category bioindicator biota for Pb accumulation.
