Abstract :

Abstract The purpose of the present study is to determine the levels of heavy metals cadmium, lead and mercury in muscle and shell in cultured shrimp, Fenneropenaeus indicus. At first, 6 kg shrimpsamples (90 pieces) were prepared from Hormozgan province. Elements were assayed by using Perkin Elmer 4100 atomic absorption using one-way ANOVA. The results showed, average mercury levels in muscle and skin, respectively, 0.017±0.002 and 0.025±0.001 mgKg-1. Average lead levels in muscle and skin, respectively, 0.072±0.003 and 0.107±0.006 mgKg-1. Average cadmium levels in muscle and skin as well as the 0.045±0.002 and 0.056±0.009 mgKg-1. Heavy metals in cultured shrimp muscle was lower than shell. High levels of heavy metals in muscle and skin were Pb<Cd <Hg. Cd levels in muscle were higher than the World Health Organization and FDA standards.
