Heavy Metals Concentration Levels in some Fish Species in the Red Sea and Gulf of Aden-Yemen

Abstract

Level of heavy metals (Zn, Cu, Pb, and Cd) in four species of fish; manly, fish, Crenidens Crenidens, Scomberomorus Commerson, Rastrelliger Kanagurta, Thunnus Albacares were studied in the Red Sea of Yemen and the Gulf of Aden. The results show that, the variations within the muscle tissues of fish were mainly attributed due to the geochemical nature of beach deposits rather than anthropogenic input. Thus it was concluded that the investigated heavy metals do not present an environmental hazards for the present time. Cd, Pb are harmful and causing the cancer diseases.
