Abstract :

The aim of this study was to determine the concentration of Copper and Hazard quotient (HQ) in muscle of the carp aquaculture fishes (common carp) (Cyprinus carpio), grass carp (Ctenopharyngodon idella), big head carp (Aristichthys nobilis) and silver carp (Hypophthalmichthys molitrix)] in Khuzestan province. 108 pieces Farmed fish sampled was prepared from the Azadegan warm water fish culture center (Ahwaz), Shosh and Shahid Ahmadian (Khoramshahr) in 2014. Copper concentration measured by wet digestion and atomic absorption spectrometer Perkin Elmer 4100. The results showed that the highest Copper concentrations between fish muscles was  on Aristichthys nobilis equal to 0.83 µg/g wet weight, that this amount and the amount of Copper in the muscle of Cyprinus carpio and Hypophthalmichthys molitrix were significantly different (P<0.05). The lowest amount of Copper in the muscle of fishes was on Hypophthalmichthys molitrix equal to 0.68 µg/g Wet weight, that this amount and the amount of Copper  in the muscle of Aristichthys nobilis were significantly different (P<0.05). Hazard quotient in all samples was less than 0.1and so fish nutrition no risk in terms of the amount of Copper in the human body.
