Determination of Fe, Zn, Pb and Cd in the lesser tigertooth croaker (Otolithes cuvieri Trewavas, 1974) (Sciaenidae) collected from Karachi Fish Harbor
In this study, Fe, Zn, Pb and Cd have been measured in muscle tissues ofOtolithes cuvieri collected from Fish Harbour West Wharf Karachi, Pakistan during theyear of 2008. The Fe concentrations in fish tissues were 6 to 88 times higher than those ofother heavy metals. Cd was the lowest in the tissues. Fe, Zn, Pb and Cd levels in ediblemuscle of O. cuvieri ranged from 15 to 54 μg Fe/g, 2.56 to 9.43 μg Zn/g, 0.13 to 0.87 μgPb/g and 0.11 to 0.92 μg Cd/g, respectively.The values obtained lower as compared tomaximum permissible limit of the food regulations and international standards and wouldnot pose any health hazards to human consumption.
