The objective of this Metals, Heavy study was to evaluate and compare the concentration of heavy metals, lead, nickel, iron Food Chain and copper in muscle tissue of blue swimming crab Portunus plagicus in three regions Health (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 © 2016. American Journal of Life sample 180, were isolated muscle tissue.

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.
