Abstract

The level of the heavy metal in green tiger shrimp (Penaeus semisulcatus) and crab (Portunus pelagicus) caught off the Persian Gulf near Bushehr province were investigated. This study was performed to evaluate instrumental neutron activation analysis (INAA) to analyze heavy metal concentration in crab and shrimp whole body tissue. The order of the swimmer crab and shrimp heavy metal concentrations were Zn>Fe>As>Mn>Co and Fe>Zn>Mn>As>Co, respectively. The results showed swimmer crab (Portunus pelagicus) and shrimp (Penaeus semisulcatus) caught off Persian gulf, were contaminated with high level of As (21.38±3.31ppm and 8.28±2.82 ppm, respectively). High levels of As and Mn were noted in crabs and shrimp, respectively.

Highlights

Heavy metal pollutions are hazardous contaminants in food and the environment
According to the World Health Organization (World Health Organization 1995) heavy metals must be controlled in food sources in order to assure public safety
This study is aimed in determining the concentrations of the heavy metal contamination (Mn, Fe, Zn, Co and As) in green tiger shrimp (Penaeus semisulcatus) and blue crab (Portunus pelagicus) by using instrumental neutron activation analysis (INAA)

Summary

Introduction

Heavy metal pollutions are hazardous contaminants in food and the environment. They are not biodegradable and have long biological halflives. According to the World Health Organization (World Health Organization 1995) heavy metals must be controlled in food sources in order to assure public safety. Excessive concentration of food heavy metals is associated with the etiology of a number of diseases, especially cardiovascular, renal, neurological, and bone diseases (Chailapakul et al 2008). A major reason to monitor levels of toxic metals in foods follows from the fact that contamination of the general environment has increased. It is known that some shrimp and crab may provide useful means of monitoring such elemental concentration levels and their impact on the aquatic environment. In 2005 BU-Olayan and Thomas showed higher trace metal levels in benthic molluscs and annelids of Kuwait Bay in the Persian Gulf compared to other regions of the word. Al-Mohanna and Subrahmanyam (2001) demonstrated
