Abstract :
The aim of this study was to determine levels of heavy metals, cadmium and lead, in muscle tissue of Barbus sharpeyi, Barbus grypus, Barbus xanthopterus, Barbus luteus and Aspius vorax in Hour-Al-Azim wetland. For this purpose, samples have been taken randomly from 2 stations (Rofae’ and Shat-Ali). Muscle tissues which were sampled over the months, within the same year, were analyzed. Preparation and analysis of samples were performed by Moopam international standard method (atomic absorption) and then were compared with recommended international standards and guidelines for these heavy metals. The results showed that maximum levels of lead have been detected in Aspius vorax of Shat-Ali station (1.62 ppm) and minimum levels have been detected in Barbus grypus of Rofae’ station (0.5 ppm). For cadmium, maximum and minimum concentrations accumulated in Barbus xanthopterus and Barbus luteus of Shat-Ali station (0.09 ppm) and Barbus grypus of Shat-Ali station (0.02 ppm), respectively. Based on these results, some fish species in Hour-Al-Azim wetland were infected with high concentrations of lead and cadmium and, therefore, consumption of these species may have potential risk for human health and should be approached with consideration.
