A Study on Levels of Heavy Metals (Fe, Pb and Cr) in Muscle of Fenneropenaeus indicus in Jask and Strait of Hormuz

Heavy metals can easily contaminate aquatic animals especially shrimps, which are one of the most valuable resources in the food chain of humans. The aim of this study was to evaluate the concentration of heavy metals (Fe, Cr and Pb) in the muscle tissue of Fenneropenaeus indicus in Jask and Strait of Hormuz and compare them with global standards. Thirty samples of Fenneropenaeus indicus were obtained in October 2015 from daily hunting of fishermen in Jask and Strait of Hormuz. Then the muscle tissues were washed and dried in oven at 65 °C for 74 hours. Following acid digestion, the measurement of heavy metals concentration was performed by Atomic absorption spectrometry. Results showed that there was a significant difference between Cr, Fe and Pb concentrations in shrimp muscle in Jask and Strait of Hormuz (P
