Heavy Metal Contaminants in Tissues of the Garfish, Belone belone L., 1761, and the Bluefish, Pomatomus saltatrix L., 1766, from Turkey Waters

摘要

Levels of contaminants in fish are of particular interest because of the potential risk to humans who consume them. Fish samples were collected through the coastal waters of Turkey and the contents of cadmium, cobalt, chrome, copper, iron, manganese, nickel, zinc and lead in the liver and muscle tissues were determined. Among the metals analyzed, copper, zinc and iron were the most abundant in the different tissues while cadmium and lead were the least abundant both in Belone belone and Pomatomus saltatrix. Metal concentrations in muscles of fish species were found 0.01-0.38 mg kg(-1) for cadmium, 0.01-0.53 mg kg(-1) for cobalt, 0.05-1.87 mg kg(-1) for chromium, 0.21-5.89 mg kg(-1) for copper, 9.99-43.3 mg kg(-1) for iron, 0.14-1.33 mg kg(-1) for manganese, 0.06-4.70 mg kg(-1) for nickel, 0.09-0.81 mg kg(-1) for lead, 3.85-15.9 mg kg(-1) for zinc, respectively. Regional changes in metal concentration were observed in the tissues of both species, but these variations may not influence consumption advisories.
