The present study was carried out to investigate contamination of heavy metals Pb and Zn in liver and muscle in Scomberomorus guttatus, Scomberomorus commerson and Otolithes ruber from Persian Gulf, Iran, in 2011. Heavy metal levels in fish samples were analyzed by Perkin Elmer 4100 zl atomic absorption. The results show that the highest concentration of Pb and Zn in the liver of Scomberomorus commerson 0.64±0.04 and 8.39±0.20 mgKg-1dw and the determined lowest concentration of Pb in the muscle of Scomberomorus guttatus 0.40±0.01 mgKg-1dw. The determined lowest concentration of Zn in the muscle of Otolithes ruber 4.66±0.36 mgKg-1dw. This study concentration of heavy metals Zn and Pb in the liver and muscle of Scomberomorus commerson, Otolithes ruber and Scomberomorus guttatus significant difference between (P<0.05). The mean estimated concentrations for Zn in the present study were lowest than International Standards for these metals as declare by the Ministry of Agriculture, Fisheries and Food (UK) and National Health & Medical Research Council (Australia), but concentrations of Pb in this study were lowest than International Standards World Health Organization (WHO), Ministry of Agriculture, Fisheries and Food (UK) and National Health & Medical Research Council (Australia).
