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