Miankaleh and Gomishan International Wetlands are important wintering areas for waterbirds in the Caspian Sea region. Previous studies revealed increased exposure to metals some species of using these wetlands. In this study, we examined concentrations cadmium (Cd), chromium (Cr), iron (Fe), lead (Pb), zinc (Zn) kidneys, liver, pectoral muscle Gadwall (Anas strepera) Common Teal crecca) collected 2012. addition, measured elements water sediments from collection sites. The genders differed only one element/tissue combination, i.e., Fe were greater livers males. Concentrations observed generally higher than Teal; renal Cr Zn did not differ between species. Mean Cd exceeded background levels, reaching 1.94 μg/g ww kidneys 1.09 liver. Similarly, Pb also elevated (4.14 3.22 liver). other within ranges commonly found waterfowl. environment above comparable with data obtained region by scientists. However, levels deemed be great enough pose an acute health risk Given duck tissues, further inquiry into source is needed area.
