This research aims to study is the pattern of  metal elements accumulation including copper, zinc, nickel and lead in the muscle, gills, liver and kidney of Schizocypris altidorsalis, in Chahnimeh reservoirs of Sistan. For this purpose, 40 samples were collected randomly from the population in winter and spring (20 samples each season). In the next phase of the research, muscle, gill, liver and kidney tissues of the samples were cut out for further study. Then, the concentrations of heavy metals were measured using atomic absorption. The samples were already prepared and treated by nitric acid of high concentration. The results of the study showed that concentrations of copper, zinc and nickel in muscle tissue in winter season were 43.01±1.39, 143.08±0.63, 8.01±0.53 and 1.13±0.18 µgr.gr-1 dry weight, respectively. Also these results in spring were 42.90±1.50, 141.04±3.02, 7.07±1.56 and 4.32±0.22 µgr.gr-1 dry weight respectively. Totally, the highest amount of copper and zinc elements in the liver tissue and lead and nickel elements were measured in gill tissue. Finally, the results of the current research showed that the concentrations of these metals in muscle tissues are higher than limits set by FAO and WHO standards. But, the concentration of nickel was lower than FDA standard.
