Background and purpose: Presence of heavy metals in the environment could constitute a hazard to food security and public health. These can be accumulated in aquatic animals such as fish, therefore, this study was conducted to investigate the As, Hg, Zn, Pb, Cd and Cu concentrations in muscle tissue of Cyprinus carpio in Taham Dam Lake in 2013. Material and Methods: Twenty five fish samples were randomly collected from Taham Dam Lake. After acid digestion, As, Zn, Pb, Cd and Cu concentrations were determined by ICP–OES and Hg concentration was determined by direct mercury analyzer. Data was analyzed using SPSS. Results: The results showed that mean concentrations of As, Hg, Zn, Pb, Cd and Cu in muscle tissue samples were 17.0±5.0, 26.0±4.0, 42.0±6.0, 5.0±1.0, 8.0±2.0, and 4.0±1.0 ng/g (wet weight), respectively. The mean concentrations of metals were significantly lower than permissible limits recommended by FAO/WHO (P<0.05). Conclusion: Although concentrations of studied heavy metals is lower than standard levels but mismanagement of water resources of the Taham Dam Lake could pollute the environment and increase the heavy metals accumulation in fish tissue, thereby endangering the health of consumers.
