Abstract

The present study was carried out to investigate contamination of heavy metals Pb and Zn in liver and muscle of Scomberomorus guttatus, Scomberomorus commerson and Otolithes ruber from Persian Gulf, Iran, in 2001 and 2011. Heavy metal levels in fish samples were analyzed by Perkin Elmer 4100 Zl atomic absorption. The results show that the highest concentrations of Pb and Zn in the liver of Scomberomorus commerson and Scomberomorus guttatus were 0.96±0.03 (2001) Scomberomorus commerson,and 213±7.35 (2001) mgkg-1dw and the lowest concentrations of Pb and Zn in the liver of Scomberomorus guttatus and muscle of Otolithes ruber were 0.28±0.04 (2001) and 4.66±0.36 (2011) mgkg-1dw. Concentrations of Zn and Pb in the liver and muscle of Scomberomorus commerson, Otolithes ruber and Scomberomorus guttatus have significant difference between 2001 and 2011 (P<0.05), except Pb in muscle of Scomberomorus commerson and in liver of Otolithes ruber (P≥0.05).
