Measure and Compare Some Heavy Metals in Muscle Tissue of Blue Swimming Crab Portunus pelagicus in Some Areas of the Southern Persian Gulf

Abstract

Heavy metals from industrial development and release it at a cost, which is resistant against degradation and the amount of fish as a human food chain accumulate. The objective of this study was to evaluate and compare the concentration of heavy metals, lead, nickel, iron, zinc and copper in muscle tissue of blue swimming crab Portunus plagicus in three regions (Qeshm, Khamir port left port) was conducted in the Hormozgan Province. Sampling was conducted in summer and winter 1394. After the captured biometric sample 180, was isolated muscle tissue. The preparation and analysis of samples was performed according to standard methods MOOPAM. Data analysis was performed using (SPSS) software, version 19 to compare of heavy metals ANOVA and Tukey tests were used in the study. 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?
