ABSTRACT

 

The research aimed to monitor the pollution level at Kamal estuary by assessing the concentration of heavy metal (Hg, Cd and Pb) using green mussel (Perna viridis L). There were 3 study sites which were near the coast of Kamal estuary (station 1), in the middle between station 1 and 3 (station 2) with length of 2 km from the coast and length of 3 km from the coast, near Bidadari Island (station 3). Each stations was comprised in 3 samplings site and it was 1 km length between one to the others. Water sampling was conducted with 3 times repetition at each sampling site. It was found that the concentration of Hg, Cd and Pb in sea water around Kamal estuary were 0.0001-0.0002 mg/l, 0.00001-0.00002 mg/l,, and 0.0013-0.004 mg/l,, which were still lower than treshold standard issued by Indonesian government. Neverthelles, it was much higher concentration of heavy metals in green mussel which were 0.0017-0.012 mg/l,, 0.46-0.743 mg/l,, and 0.92-1.485 mg/l,. It seems that green mussels absorbed heavy metal dissolved in sea water which were accumulated in their body, indeed. The weight of green mussel did not differ significantly to accumulate heavy metal (p>0,05), although higher concentration of heavy metals was found in the small green mussel than the bigger ones. Thus, green mussel could be used as bioindicator of heavy metal pollution in sea water.
