title: Levels of Total Mercury in Tissues of Mallard Drakes from Industrialized Wetlands Area.
abstract: The distribution of total mercury in the bodies of drake mallard ducks (Anas platyrhynchos) inhabiting an industrialized wetland area in southern Poland was studied. The median Hg concentration in tissue of various bones (0.017 µg/g w.w.) was statistically lower than the concentration found in muscle tissue (0.023 µg/g w.w.) and in internal organ tissue samples calculated across the whole range of organ types (0.036 µg/g w.w.). The median concentrations in muscle tissue and organ tissue were comparable. Significant differences within the examined bones were observed, with the beak accumulating the highest amount (0.105 µg/g w.w.). Concentrations were comparable in tissue from various muscles, whereas internal organ tissue displayed a significant variation. The highest median concentration was detected in the kidneys (0.109 µg/g w.w.). Correlations of Hg concentrations between major groups of tissue (i.e. bone, muscle and internal organs) were not statistically significant, but several significant relationships were noted between internal organs.
