This study was undertaken to determine the concentrations of arsenic and mercury in edible muscle of pelagic (Scomberomorus commerson, Chirocentrus dorab, Sphyraena jello, Rachycentron conadum, Thunus tonggol), benthopelagic (Trichiurus lepturus, Caranx sem, Pampus argenteus, Parastromateus niger) and demersal (Nemipterus japonicas, Epinephelus coioides, Platycephalus indicus, Psettodes erumei, Pomadasys argenteus, Acanthopagrus latus) fish species from the Persian Gulf during summer and winter. The samples were analyzed by graphite furnace atomic absorption spectrometry (GFAAS) for arsenic and cold vapor atomic absorption spectrometry (CVAAS) for mercury after wet-ashing digestion. The results were expressed as mu g/g of wet weight. The resulted range of contamination in fish species was between 0.156-0.834 mu g/g for arsenic; and 0.120-0.527 mu g/g for mercury. Also study revealed that seasonal variation influenced the concentration of the metals in the fish samples. The highest concentration of arsenic and mercury was found in Epinephelus coioides (1.011 mu g/g) and Thunus tonggol (0.548 mu g/g) in winter, respectively. Moreover, demersal fish species had the highest arsenic (0.481 mu g/g) and mercury (0.312 mu g/g) concentrations. Our study demonstrates that estimated daily and weekly intakes of arsenic and mercury via consumption of fish flesh were far below the PTDI and PTWI values established by FAO/WHO.
