This study evaluated the concentration of heavy metals including lead, cadmium, zinc and copper in edible tissues of Caspian Kutum (Rutilus frisii kutum) in Miankaleh International Wetland and the health risk resulted from consumption of this fish. Material and Methods: During fishing season, 20 White fishes were collected from Miankaleh International Wetland with the permission of Environmental Protection organization. The densities of heavy metals in skin and muscles were determined using atomic absorption (Scientific Equipment GBS). Data was analyzed using SPSS V.16. Results: The mean densities of lead, cadmium, zinc and copper in the skin were 3.4, 0.48, 40.55, and 3.3, respectively and 2.1, 0.39, 16.52, 4.5 microgram per gram of the wet weight in muscle tissues, respectively. A significant difference was seen in the concentration of heavy metals between the skin and the muscle tissue (p M3 ER -
