Background and purpose: Heavy metal contamination of aquatic ecosystems is a major concern for animals and human health. Pollutants such as heavy metals accumulate the food chain and at the end, they transmit to the human body. In this research, the concentrations of nickel, lead and cadmium in Barbus grypus of Dez River, Iran, were determined and compared with international standards. Materials and methods: 30 Barbus grypus were caught from the central area of Dez River (city of Dezful). Then, the fishes were digested in concentrated nitric acid, and nickel, lead and cadmium concentrations were measured using graphite furnace device. Results: The concentrations of lead, cadmium and nickel in the gill tissues were 0.281 ± 0.013, 0.156 ± 0.009, and 0.315 ± 0.070 ppm, respectively. The concentrations of lead and cadmium were significantly higher in gill tissue compared to muscle (P < 0.05). Conclusion: The results indicate that the concentrations of nickel, lead and cadmium in Barbus grypus of Dez River were less than the World Health Organization standards.
