Levels of Heavy Metals in Fishes (Cheilinus trilobatus) from the Gulf of Aqaba, Jordan

Heavy metal concentrations of Ni, Mg, Co, Cr, Cd and Cu were investigatedusing flame Atomic Absorption Spectrophotometer (AAS) in the liver, kidney, muscle, scale, gonad, gill and stomach of Cheilinus trilobatus fish species from the northern Gulf of Aqaba. Cheilinus trilobatus fish species were collected during the period May to August 2013. The results indicated significant differences between different organs of Cheilinus trilobatus for Ni (p = 0.0002), Fe (p = 0.0213), Co (p p Cheilinus trilobatus and its length. The levels of metal concentration of the present study were generally lower or within the ranges of those found in the fish of the Red Sea. After all, Cheilinus trilobatus fish species was found to be safe for consumption and do not pose a significant threat to the health of human consumers.
