The Study of Some Heavy Metals (Lead, Nickel, Zinc, Copper and Iron) in Muscle Tissue of Blue Swimming Crab Portunus pelagicus in Some Areas of the Hormozgan Province, Iran

Abstract

After absorption of heavy metals in the tissues of aquatic organisms in aqueous solution accumulate and enter the human body through the food chain and proportional to the concentration of toxic metals absorbed, clinical effects observed. The objective of this study was to evaluate and compare the concentration of heavy metals, lead, nickel, iron and copper in muscle tissue of blue swimming crab Portunus plagicus in three regions (Qeshm, Khamir port and Laft port) was conducted in the Hormozgan Province. Sampling was conducted in summer 2015 and winter 2016. After the captured biometric sample 180, were isolated muscle tissue. The preparation and analysis of samples was performed according to standard methods MOOPAM. The results show that the studied concentration in muscle tissue of blue swimming crab (Portunus pelagicus) at sample locations statistically significant difference shows. Also studied in terms of concentration in the muscle tissue of blue swimming crab in the study area between summer and winter statistically significant difference was observed (P < 0.05). As both in summer and winter concentrations of lead, nickel, iron and copper in muscle tissue of blue swimming crab in Qeshm is greater than the other two regions. Meanwhile, the results of the study compared concentration in muscle tissue showed blue swimming crab with international standards. The studied concentration in muscle tissue of blue swimming crab in Qeshm, Khamir port and Laft port international standards is less than the limit. Which indicates that the health of aquatic ecosystems contamination is not a problem.
