Abstract
- The present study aimed to measure the concentrations of Sn, Pb, Zn, Hg, Cu, Ni and Cd in the muscle and liver of 40 Common Moorhens (Gallinula chloropus) hunted from four stations in Anzali Wetland (Pirbazar, Ghalam-Koudeh, Selkeh and Abkenar). The histopathologic alteration index (HAI) of liver and kidney was also assessed in these birds. The highest concentrations of selected metals were measured in the liver of birds collected from Ghalam-Koudeh (Pb: 4.59±0.21, Sn: 6.663±0.282, Zn: 29.867±2.011, Cu: 24.07±1.84, Hg: 7.5±0.257, Ni: 6.85±0.52, Cd: 1.879±0.4mg kg(-1) dw). The lowest concentrations of metals were measured in the muscle of birds caught from Abkenar (Pb: 0.799±0.207, Sn: 1.873±0.066, Zn: 18.533±1.582, Hg: 0.86±0.08, Ni: 0.53±0.117, Cu: 6.63±1.114, Cd: 0.08±0.002mg kg(-1) dw). Also the highest and lowest concentrations of metals were recorded in sediment of Ghalam-Koudeh and Abkenar stations, respectively. These stations were located next to multi-industry Anzali Port. However, the concentration of Sn and Zn in sediment and tissues of Common Moorhens collected from different stations was lower than the permissible limit suggested by WHO and Canadian Council of Ministers of the Environment (CCME). But, Pb, Hg and Ni concentration in sediment and birds caught from all stations was higher than the permissible limit defined by WHO and CCME. Cu and Cd concentration in tissue samples and sediment of Ghalam-Koudeh and Pirbazar was also higher than the permissible limit defined by WHO and CCME. Hemorrhage, melanomacrophage aggregations, sinusoidal congestion and hepatocyte vacuolation were the most pathological changes found in the liver. Reduction of the Bowman space, melanomacrophage aggregations and hemorrhage also were observed in the kidney. The HAI means of G. chloropus collected from Ghalam-Koudeh and Pirbazar were significantly higher than other sites. Based on the HAI values and metal bioaccumulation in the tissues of G. chloropus, Ghalam-Koudeh and Pirbazar could be considered as having the worst environmental quality.<br /> (Copyright © 2014 Elsevier Inc.
