The concentration of 10 metals [Cadmium (Cd), lead (Pb), mercury (Hg), copper (Cu), iron (Fe), manganese (Mn), aluminum (Al), arsenic (As), nickel (Ni) and zinc (Zn)] were measured in muscle, gill and liver of 14 species from Hormoz Strait in North Costal of Persian Gulf in 12 months (April 2009 to March 2010). All samples were analyzed for Cd, Pb, Cu, Fe, Mn, Al, As, Ni and Zn concentrations by inductively coupled plasma-atomic emission spectrometry (ICP-AES) and for Hg by LECO AMA254 Advanced Mercury Analyzer. Results of our study showed, Iron had highest concentration (total mean concentration) in all species, and followed by Zn, Cu, Ni, Al, Pb, Mn, Cd and Hg and lowest concentration in three tissues was As. In addition the accumulation of metals was species-dependent, and was higher in Scomberomorous commerson and Thannus tonggol (p<0.05) and the lowest concentration was recorded in Sardinella sindensis (p<0.05).
Key words: Metal, Persian Gulf, fish.
