Nowadays, monitoring of heavy metals accumulation in aquatic tissue is one of the important research approaches to assessment of ecosystem health. This study investigated bioaccumulation of five heavy metals (cadmium, lead, zinc, chromium, and copper)in muscles of two fish species, Cyprinus carpio and Sander lucioperca in the Ilganeh Chai River. During 2020-2022, totally 52 samples (25 Zander and 27 Carp) were randomly taken where the Ilgineh River drains into the Ilgineh River Basin. The tissues of each fish were separated and digested in the lab and then analyzed using an atomic absorption spectrophotometer. Comparison of the mean concentrations of the heavy metals showed that the highest bioaccumulation levels in both fish species belonged to copper and the lowest to cadmium. These highest levels were lower than the maximum permissible levels set by the World Health Organization. The food-safety risk assessment of the heavy metals indicated that the estimated daily intake (EDI) value was lower than the tolerable daily intake (TDI) and risk assessment on non-carcinogenicity showed the highest levels of THQ were found for cadmium and the value of total non-carcinogenic (HI) for none of the elements was not higher than one . In addition, the highest value of cancer risk (CR) index belonged to cadmium (8×10-5), which was lower than the international standard permissible limit (1×10-4). Overall, the comparison of the bioaccumulation levels of the heavy metals in muscles of fish species examined with health index and international indicated that consumption of fishesare safe for human in this river.
