Abstract
Heavy metals are importantly concerned due their biological accumulation and toxicity in terms of human health. Common carp is one of the most popular seafood in the North of Iran especially in Golestan province. In this descriptive-analytical research, about 30 samples of common carp were collected from Ala gul and (n: 24) and Alma gul (n: 6) wetlands. Once the samples were prepared by polarography device, the concentration of lead, cadmium, zinc and copper were measured in the muscle tissue of carp. The value of THQ in children and adults was estimated according to the equations of risk assessment. The mean concentration of zinc, lead, copper and cadmium was 120.9 ±106, 7.92 ±7.9, 5.84 ±5.22 and 0.027 ±0. 043 mg/kg in Ala gul wetland and 67.42±33.43, 3.24± 1.04, 4.36±2.77 and 0.005±0.008 mg/kg in Alma gul wetland , respectively. The order of heavy metals’ concentration in both wetlands was Cd <Pb <Cu <Zn. Although the concentration of copper, lead and zinc was significantly higher than the standard limit, the results of risk assessment showed that THQ was less than 1 for all the heavy metals except for lead (in children group); therefore, it can be concluded that the consumption of common carp fish in Ala gul and Alma gul wetlands does not hazard adult’s health.
