The aim of this study was to investigate the concentration and evaluate the health hazard of heavy metals ) Lead, Chromium, Copper, and Zinc( in muscle tissue of Cyprinus carpio and Ctenopharyngodon idella in Bashar River, Yasuj. In order to assess the concentration of metals in fish and the health risks of their consumption, 60 fish samples were taken in different parts of the river (before, in, and after Yasouj city), and after preparation and acid digestion of samples, the concentrations of these metals were determined by using atomic absorption spectroscopy. In order to assess the risk of fish consumption, Consumption Rate Limit (CR_lim)؛, Metal Pollution Index (MPI), Hazard Quotient (HQ), and Hazard risk (HI) of metals were used. The results showed that the average total concentration of Cr, Pb, Zn, and Cu in Cyprinus carpio and Ctenopharyngodon idella were (1.21± 0.76, 2.83 ± 1.26, 36.1±13.46 and 16.29 ±2.1) and (0.84±0.68, 2.09±1.48, 32.93±8.06 and 9.57±5.88) mg/kg, respectively. The amount of MPI, CR_lim, showed that contamination and health risk of consumption of C. carpio were significantly higher than C. idella. The results showed that the level of a health risk index for C, carpio and C. idella species were 0.348 and 0.244, respectively. Also, the amount of Hazard index (HI) in both fish species was less than one. According to the results although the concentration of metals in fish does not have a health risk for consumers, continuing the trend of entering various pollutants from urban, industrial, and agricultural wastewater into the river can lead to the accumulation of these elements in the food chain of the ecosystem, caused a serious threat to the health of living creatures and their consumers.
