Study bioaccumulation of heavy metals in Penaeus semisulcatus from the Northern part of Persian Gulf

Variety of operations, such as oilexploration and industrial and agricultural activities, themarine environment has become contaminated with a widerange of pollutants, causing much concern over the lastfew decades. The accumulation of heavy metals which are as the results of industrial, urban and agriculturalsewages are usually resistant to chemical dissociation. They can easily contaminate aquatic animalsespecially shrimps which are one of the food chains of humans. This study was conducted in order to bioaccumulation of heavy metals Zn, Cu, Cd, Hg, Pb and Ni in muscle of Penaeussemisulcatusnative species of Hormozgan Province in summer of 2015, 100 samples were collected from station of Dayer portfromthe Northern of Persian Gulf. Then Biometry and preparation of muscle samples, metals were extracted using acid digestion method and concentration of heavy metals was measured by Atomic Absorption Spectrophotometer. The detected concentration ranges of the elements in the edible tissues, reported as mg g-1 wet weight, were as following: Zn (12.48-14.16), Cu (5.92-6.42), Cd (0.004-0.01), Hg (0.08-0.22),Pb (0.34-0.68) and (0.14-0.38). The comparison results of metal concentrations in muscle tissue of shrimp with FDA, WHO and FAO standards showed that the surviedheavy metals content in muscle tissue is lower than the permissible level for human consumption and requires further monitoring.
