Heavy Metals Accumulation on Green Mussel (Perna viridis) in Jakarta Bay)

Abstract

Jakarta is Indonesia's economy and government center and the most populated city. Besides that, Jakarta is also a home for many industries. All of these activities produce large number of waste and waste water that are usually discharged without any further treatment into the river streams, and cause heavy pollution. Polluted water at Jakarta Bay, especially from heavy metal, affect the organisms that live in this area, especially green mussel (Perna viridis). The objectives of the research were to examine the bioaccumulation of heavy metal (Hg, Cd, Pb) on green mussel. The observed parameters were water pollution indicator, heavy metal accumulation and percentage of green mussel mal formation. The result of several water pollution parameters indicated that they were higher than the allowed limit. This situation could be avoided by the developmnet and implementation of the Waste Water Treatment Plant to treat the waste water before being discharge to the river stream.
