Jakarta Bay has become contaminated by both organic and inorganic pollutants, including heavy metals. This study aimed to examine the effect of heavy metal pollution on green mussels cultured in Muara Kamal Waters, Jakarta Bay over seven months. In this research, the water quality was assessed, through measuring the concentrations of the heavy metals, Hg, Pb, Cd, Cr, and Sn in the water, and in the tissue of green mussels that had been cultured there for seven months. The percentage of congenital abnormalities (malformations) in the green mussels was analyzed descriptively and the relationship between the water quality, heavy metals, and green mussel malformation was studied through principal component analysis (PCA). The result showed that the heavy metals concentrations in the water and sediment exceeded the quality standard at Muara Kamal but that in other respects the water quality was quite good. The green mussels cultured there for seven months had accumulated high concentrations of heavy metals, and ±60% of them had malformations of their shells. Based on the heavy metal concentrations in their bodies, the main cause of malformations in green mussels was suspected to be Pb, Hg, and Sn. However, the result of PCA showed it was the interaction between nitrogen compounds, phosphate, turbidity, salinity, pH, as well as the heavy metals in the water that determined the green mussel abnormality.
雅加达湾已受到有机和无机污染物的污染，包括重金属。本研究旨在检验重金属污染对雅加达湾勿拉湾水域养殖绿贻贝七个月的影响。在这项研究中，通过测量汞、铅、镉、铬和锡等重金属在水中和已在那里养殖了七个月的绿贻贝组织中的浓度来评估水质。对绿贻贝的先天性异常（畸形）百分比进行了描述性分析，并通过主成分分析（PCA）研究了水质、重金属和绿贻贝畸形之间的关系。结果表明，勿拉湾的水中和沉积物中的重金属浓度超过了质量标准，但在其他方面水质相当好。在那里养殖了七个月的绿贻贝积累了高浓度的重金属，其中±60%的贻贝壳有畸形。根据其体内重金属浓度，绿贻贝畸形的主要原因疑似为 Pb、Hg 和 Sn。然而，PCA 的结果表明，决定绿贻贝异常的是水中的氮化合物、磷酸盐、浊度、盐度、pH 值以及重金属之间的相互作用。
