Green mussels, Perna viridis, heavy metals, atomic absorption spectrophotometry.
The monitoring of environment is needed to evaluate the health of environment. Muara tawar is a water
ecosystem in Jakarta and a series of observation is needed since it is known as an area of steam power plant. In this
experiment we concern over the accumulation of several heavy metals in this area. Heavy metal, affects the
organism that live in this area, especially green mussel (Perna viridis). Green mussels are coastal bivalves, typically
occurring at depths of less than 10 m, and shown to be tolerant of a wide range of turbidity and pollution. in this
experiment, we used soft tissue, shells, and the sediment. The samples were collected at three different locations in
muara tawar which is known as an area of steam power plant. Cadmium, Plumbum, and Mercury were chosen as the
main contaminant indicator in waters and were analyzed by flame atomic absorption spectrometry. Furthermore, the
concentrations of cadmium over those three sample were very small and can not be detected by the equipments.
Plumbum were also can not be detected in muscle tissues and shell but positively detected with average 19.303 ppm in
three different sampling station. Mercury content indicate a serious polution in muara tawar water ecosystem with
average 40,77 ppb in sediments, 48,47 ppb in muscle tissues, and 4,9 ppb in shell.
