In this study an ICP-OES (inductively coupled plasma-optical emission spectrometry) was used to investigate the concentration levels of both essential and non-essential elements in 70 edible portion of fish samples representing 11 different species of fish collected from Omani markets. Sample preparation via microwave digestion were analyzed, using ICP-OES for seven non-essential elements [Arsenic (As), cadmium (Cd), nickel (Ni), lead (Ph), titanium (Ti), chromium (Cr) and mercury (Hg)] and seven essential elements [iron (Fe), copper (Cu), zinc (Zn), phosphorus (P), calcium (Ca), selenium (Se), and magnesium (Mg)]. A comparison of the results for the concentration of Cd, Ni, Pb, Ti, Cu and Fe elements between the species of fish showed that there was significant (P < 0.05) difference in concentrations. Tissue samples from Seriola dumerili and Xiphias gladius tissues contained significantly (P < 0.05) higher levels of Cd, while Lutjanus argentimaculatus and Parastromateus niger samples had significantly (P < 0.05) higher levels of Ni than those from other fish species. The levels Pb found in the tissues of Merluccius bilinearis, and Lethrinus nebulosus fish were significantly (P < 0.05) higher than other fish species. Further, Lethrinus nebulosus and seriola dumerili tissue samples contained significantly (P < 0.05) higher concentrations of Ti. The concentrations of Ni and Pb were found higher than the maximum permissible limits in certain fish species samples for human consumption. The results indicated that the edible portion contained significantly (P < 0.05) higher levels of Cu in Seriola dumerili species and Fe elements in Ocyurus chrysurus and Pagellus affinis than other fish species. This study concluded that Cd, Ni, Pb, Ti, Cu and Fe elements were species-dependent.
