The study sites were located in the river mouths of Kahayan and Katingan Rivers of Central Kalimantan. The purpose of this study was to evaluate concentration of heavy metals on the water, sediment, Arius (catfish) fin through concentration and bioconcentration factor (BCF); data were analysed by regression and correlation analysis. Collected samples were water and fish.Water sample and fish bone were analysed by Atomic Absorption Spectrophotometer (AAS). The results indicated that the concentrations of Pb>Cd>Hg were occurred in the water and hard fins, which the bioconcentrations of Hg>Cd>Pb were in the hard fins, while the bioconcentration factors (BCFs) of Pb>Hg>Cd were in the sediment.Moreover, it seems that heavy metals in the waters absorpted and accumulated by sediment and hard fins increased along with heavy metal concentration in the water, whereas heavy metals in the sediment absorpted and accumulated by hard fins increased along with heavy metal concentration .in the sediment.
