Concentration of the Heavy Metals in Muscle Tissue of the Carnivorous Fishes Obtained from Udera Sthan Dam (Bihar)
Abstract: Concentration of different essential and non-essential heavy metals in water samples collected from Udera Sthan Dam was examined during present research work. The concentration of essential and non-essential heavy metals in muscle tissue of almost all five carnivorous fish species showed almost increasing trend from the month of July to September. Highest concentration of essential heavy metals remained in the muscle of Wallago attu as compared to other four carnivorous fish species examined during present study. The concentration of Arsenic was not detected during month of July and September in Channa punctata Mercury during month of July, August and September in Channa punctata and Nickel in Clupisoma garua muscle tissues. Highest concentration of Arsenic (2.123-3.906 ?g/g) was detected in muscle of Clupisoma garua as compared to other carnivorous fish species. Highest concentration of Cadmium (1.032-1.087 ?g/g) and Lead (9.802-11.623 ?g/g) were detected in muscle of Wallago attu as compared to other carnivorous fish species examined during present research work. Highest concentration of Nickel was also observed in the muscle of this fish species (9.296-20.323 ?g/g) as compared to other carnivorous fish species. But the concentration of Mercury was recorded highest in the muscle of Clupisoma garua (4.210-5.218 ?g/g) as compared to other carnivorous fish species. Lowest concentration of Arsenic in muscle of Channa punctata, cadmium Lead and Mercury in muscle of Mastacembelius armatus, and Nickel in the muscle of Channa puntata were detected during present research work.
