Distribution of Mercury in Some Organs of Anzali wetland Common cormorant (Phalacrocorax carbo)

摘要

A study conducted to screen mercury (Hg) level in the common cormorant (Phalacrocorax Carbo) of Anzali region to determine the biological behavior of this element and to assess the exposure of wild fisheating birds, which are a bio-indicator to this pollutant. Mercury concentration was measured in liver, kidney and muscle organ. The mean concentration of mercury respectively was 8.32±1.32, 9.25±1.71 and 2.064±0.22 ppm in liver, kidney and muscle. Hg concentration was highest in the kidney and liver (p<0.01). The amount of mercury accumulation obtained was as follows: Liver ~ Kidneys > Muscles. Hg concentration in the liver and muscle increased significantly with growth from juvenile to adult (p<0.05). Comparison of Hg concentration between males and females indicated that Hg concentration in the muscle (p<0.05) and kidney (p<0.01) was significantly different
