摘要
The main purpose of this study was to determine heavy metal levels (Cd, Pb, Cr, Cu, Ni, Zn, and Fe) in the edible muscle, gill, liver, and skin of common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix), in Sanandaj Gheshlagh Reservoir (SGR), Iran to evaluate their hazard levels in relation to the maximum residual limits for human consumption. The results indicated that Fe accumulated the highest level of metal in the organs of both fish species. Moreover, the highest and lowest level of metals has been accumulated in the gill and skin organs respectively. The statistical analysis indicated that the metal concentrations differed significantly among liver, gill, edible muscle, and skin in C. carpio and H. molitrix. Furthermore, the results of this study showed that the maximum allowable fish consumption rate for an adult person with mean 71.5 kg body weight were 2128, 136, 638, 1280, and 1124 g/day based on g/day based on Cd, Cu, Cr, Zn, and Fe levels respectively. In conclusion, results showed that the metal concentrations in the edible muscle of both fish species are below levels of concern for human consumption.
