Detection of Heavy Metals in the Selected Edible Fish species from Baran Dam f. R Bannu Pakistan

The objective of the research work was to determine the distributed level of Heavy metals like Copper (Cu), Zink (Zn). Iron (Fe), Lead (Pb) and Chromium (Cr) in the month of January -February 2013 at Baran Dam F.R Bannu. The recorded level of the values of all heavy metals in head, abdomen and tail in Labeocalbasu were Cr>Fe>Cu>Zn>Pb, Cu>Cr>Zn>Pb, Cr>Fe>Cu>Zn>Pb, in Labeoboga were Zn>Cr>Fe >Pb>Cu, Cr>Zn>Cu>Fe>Pb,Fe>Cr>Cu>Zn>Pb, in Notopterusnotopterus were Cr>Fe>Zn>Cu>Pb, Cu>Fe>Cr>Zn>Pb,Fe>Cu>Cr>Zn>Pb, in Mastacembelusarmtus were Fe>Cu>Cr>Zn>Pb,Cr>Cu>Fe>Zn>Pb, Cr>Zn>Cu>Pb  respectively. It indicate that Pb have the lowest concentration in all the organ of above except in head of Labeoboga fish species. Chromium was found unexpectedly in high amounts but its consumption limits were not set down yet in Labeocalbasu. The mean value for heavy metals were Zn (P
