Abstract

Blood cockle and green mussel are source of protein that vulnerable to contamination by mercury (Hg) through bioaccumulation process. The research of Hg2+ bioaccumulation ability by bloodcockle (Anadara granosa) and green mussel (Perna viridis) using the radiotracer 203Hg2+ was conducted based on laboratory experiments design. Biokinetic parameters, such as the uptake and depuration rate and Concentration Factor, were determined to obtain predictions of Bioconcentration Factor (BCF) and steady state conditions. The results of experiment using non-linear model showed that blood cockle and green mussel have the capability to accumulate Hg2+ by 15429.38 and 6963.68 times higher than its concentration in seawater after 51 days. Based on the BCF value obtained from the experiments, the predicted concentration of mercury in Anadara granosa and Perna viridis from Jakarta Bay was 1.327 and 0.599 mg.Kg-1 respectively. The predicted concentration of Hg2+ in Anadara granosa exceeds those required by ISO 7387:2009. On the other hand, the predicted in Perna viridis still meet the requirements of ISO 7387 2009.
