Abstract

Garapan, Cibungur, and Ciliman Rivermouths are known as places for fishing. Those areas are surrounded by human activities such as human settlement, agricultural and industrial activities. The aim of this study is to investigate the bioavailibility of Cd, Pb, Cu, and Zn in sediment for biota (clams) from related location. Bioavailibility was determined using sequential extraction technique consisted of residual and nonresidual fractions. Samples of sediments taken using Ekman grab, while clams Anadara pilula taken using “garo”. Heavy metals content was analyzed using AAS. Regression linear was used to see relationship between bioavalibility and heavy metal content in clams. Result showed that heavy metal content Cd, Pb, Cu, and Zn in sediment were highest in Garapan so were the content of Pb, Cu, and Zn in Anadara pilula. Result also showed that Cd and Pb were mostly bound to nonresidual fraction 100% and 54,65 – 64,69% respectively, while Cu and Zn were mostly bound to residual fraction 54,63 – 54,79% and 67,28 – 79,37%, respectively, except in Garapan for Cu. Relationship between each fraction of heavy metal in sediment with heavy metal content in Anadara pilula showed ascending pattern except, for Cd.
