ABSTRACT The aim of the present study is to determine metals (lead, copper and iron) and metalloids (sodium and potassium) in selected fish species of the Kharun River, that are frequently used for human consumption in Raipur region. Three replicates of fish species of Tilapia (Oreochromis niloticus), Cat fish (Hypostomus plecostomus) and Eel (Anguiliformes bengalensis) were collected by a standard procedure with the help of fishermen from Kharun River, Raipur, Chhattisgarh. The values of analyzed elements in the selected three fish species were significantly different from each other. Among all the analyzed elements potassium was found in highest concentration and copper in lowest, the pattern of order of elements concentration is as follows: K> Na> Fe> Cu> Pb. The result of present analysis was compared with the permissible limits set by FAO and WHO. The levels of analyzed elements bioaccumulated in tissues of the fish samples did not exceed the permissible limits. Therefore the fish in this area of study did not pose any threat to human upon their regular consumption. Periodic monitoring of trace metals in edible aquatic organisms and fish is recommended in seeking to avoid unexpected health hazards.
