Measured and Comparison of heavy metals Hg, Pb, Cd in the muscle and shell of Fenneropenaeus indicus Persian Gulf (Bahrekan), Khuzestan Province

A comparative study was conducted on concentration of heavy metalsHg, Cd, Pbin the muscle and shell of Fenneropenaeus indicus in marine, 2011. Three kilogaram were collected shrimp of marine too weight 13.18±0.78 g. Metals were extracted from the tissues using wet digestion method and concentration of the heavy metals were measured by Atomic Absorption Spectrophotometer Perkin Elmer 4100 from Kimia Pajohe Alborz labratory (Shahrekord). Concentration of heavy metals in muscle were lower than in shell of shrimp. Concentration of heavy metals in the muscle and shell of Fenneropenaeus indicus were measured Pb>Cd>Hg. In this study concentration of Hg, Cd, Pbin the muscle and shell of Indian shrimpsignificant difference (P<0.05). Mean of Hg in muscle and shell were measured 0.034±0.002 and 0.045±0.003 mgKg-1 and concentration of Cd in muscle and shell were 0.101±0.005 and 0.120±0.007 mgKg-1, respectively. Also concentration of Pb in muscle and shell were measured 0.133±0.005 and 0.164±0.004 mgKg-1. Concentrations of Cd in muscle were higher thancomparison of WHO standards. Concentrations of Hg and Pb were higher thancomparison of WHO and FDA and were lower thancomparison of UKMAFF and NHMRC.
