Abstract

The objective of this research was to know the concentration of Pb, Cr, and Hg in the body of water and sediment, and their influence on Plankton, Benthos, and Fish diversity in The Ciliwung River. In the downstream of Ciliwung River, there were only Hg and Pb were detected in the water, while in the upstream of Ciliwung River, there were no heavy metals detected. In the rainy season, Hg and Pb were not detected in the body of water. The whole of heavy metals observed was found in the sediment of the Ciliwung River. The concentration of Pb, Cr, and Hg in sediment were significantly different at the location (P<0.05), while according to the replication only Hg was significantly different (P<0.05). The relationship between Hg concentration in River sediment with Hg concentration in water was very significant (P<0.01). The correlation test on the relationship between Hg concentration in water with Plankton and Fish diversity was not significant (P>0.05), while with Benthos Diversity, it was very significant (P<0.01). The correlation test on the relationship between heavy metals concentration in River sediment with Plankton, Benthos, and Fish Diversity showed that the relationship which found significant (P<0.05) was only between Hg concentration in sediment with Benthos Diversity, and the relationship which very significant (P<0.01) was only between Pb concentration in sediment with Benthos Diversity.

Abstract

The objective of this research was to know the concentration of Pb, Cr, and Hg in Fish in the Ciliwung River. The observation of Heavy Metals concentration in Fish showed that only Hg in internal organ of Demersal Fish was significantly different according to the location and replication (P < 0.05), while Heavy Metals of Pb and Cr in Demersal and Pelagic Fish were not different according to the location and replication. It means that human activities such as industrial, settlement, agriculture and transportation along the Ciliwung River affect adsorption/absorption of Hg by Fish. Generally, Pb, Cr, and Hg concentration in the internal organ of Demersal and Pelagic Fish were higher than in the Fish Meat, because internal organ are the target organ of Heavy Metals substances in Fish. In general, metal concentrations of Pb, Cr, and Hg in the meat and organs of Demersal Fish were higher than that in the meat and organs of Pelagic Fish. This was due to the activity of Demersal Fish that forage and are active in bottom waters close to sources of heavy metal pollutants (sediment). The Result of observation show that in general, the contribution of human activities in the DKI Jakarta area to the presence of Pb, Cr, and Hg in the waters, sediment and Fish of the Ciliwung River was greater than in the Bogor and Depok areas.
