In this study, mercury (Hg) levels were determined in three fish species from Arvand river, northwest of the Persian Gulf. It was also our intention to evaluate potential risks to human health associated with seafood consumption. Mercury levels varied with sex and species. Accumulation also differed significantly in certain organs. The order of mercury levels in tissues of the fish species was as follows: liver > gill > muscle. There was a direct relationship between mercury levels in tissues fishes with food habits and habitats. The results of this study show that highest levels of mercury were found in the benthic fish (E. diacanthus) followed by bentho- pelagic fish (C. chanos) and pelagic species (S. argus). There was a positive correlation between mercury levels tissues with body size of fishes. Highest mercury levels were in tissues of female fishes because they are larger and can eat larger food items. The results confirmed that the levels of mercury in fish were strongly affected by habitat and feeding habits.
