Abstract: Three highly consumed fish in Saudi market were evaluated for their composition of heavy metals. The fish species` were included Spanish mackerel, (Scomberomorus maculates), Grouper (Epinephelus coioides) and Yellow-spotted trevally (Carangoides fulvoguttatus) which, respectively known as Kanad, Hammour and Hammam in Saudi market. The concentration of heavy metals (cadmium, zinc, lead, nickel, vanadium, arsenic and mercury) was determined in the muscle and the head of fish. The level of elements was determined by atomic absorption spectrophotometry (AA). The maximum Cd, Zn, Pb, As, Ni, V and Hg concentrations in fish samples were 49.78, 30.28, 244, 42, 138, 17.49 and 2.84 ng g ¹, respectively. The concentration of metals was below the maximum allowed limit by the Saudi and International Legislations for fish human consumption permissible limit.
