Determination and Comparision of Heavy Metals (Ph, Cd, Zn, Ni) in Some Commercial Fishes and Green Tiger Prawns Penaeus Semisulcatus in Bushir Area

Abstract:
The concentrations of cadmium, nickel, lead, and zinc in the four commercial species; Silver pomfret(Pampus argenteus), King mackerel. (Sc0l1l,beromorous commerson), (pomaclasys kaakan), and Green tiger Prawns (penaeus semisulcatus) were determined in the Persian Gulf all were collected from the Bushir coast. The samples were digested by ultrapure. nitric acid, and then analyzed using the atomic absorption spectrophotometry technique. The results show that samples contain 0.4 to 4.45, ?g/g dry weight for Cd, 1.3 to 157.1, ?g/gdry weight for ni 1.9 to 37.25, ?g/g dry weight for Pb, and 39 to 180.25, ?g/ gdry weight for Zn. Significant difference were seen between mean ofconcentrations of Cd, Ni,and Zn green tiger prawns (penaeus semisulcatus) with other species
