Comparison of the Metal Concentrations in Organs of Two Bird Species from Western of Iran

This study was conducted to measure the concentration of several elements (Cd, Pb, Cu, and Zn) in organs of Coot, Fulica atra, and Mallard, Anas platyrhynchos, in order to: (1) determine the significant between metal concentrations in different organs (kidney, liver, pectoral muscle, and feather), (2) to evaluate species differences in metal exposure and accumulation, and (3) to study gender-related trends in metal accumulation. The metal concentrations in organs of F. atra and A. platyrhynchos decreased in the following order: Zn > Cu > Pb > Cd. These results revealed that there were no significant differences between males and females except for Cu in liver and feather, and Pb in kidney.
