The assessment of trace metals at gill, muscle and liver tissue in Mugil cephalus.

In this paper, concentrations of trace metals such as Cr, Mn, Fe, Ni, Cu, As, Se, Ag, Cd and Pb were determined in Mugil cephalus of the middle Black Sea coasts by employing inductively coupled plasma mass spectrometry (ICP-MS) and microwave digestion technique. Different parts of fish samples were analysed separately such as the gill, muscle and liver. The accuracy of the results has been checked by using a certified reference material (DORM-4). The highest trace metal values determined in different parts of fish were Cr in muscle tissue (0.416 μg/g), Mn in gill tissue (52.246 μg/g), Fe in muscle tissue (11.899 μg/g), Ni in muscle tissue (108.057 μg/g), Cu in liver tissue (261.911 μg/g), As in liver tissue (4.162 μg/g), Se in liver tissue (11.418 μg/g), Ag in liver tissue (0.323 μg/g), Cd in liver tissue (1.11 μg/g) and Pb in gill tissue (3.047 μg/g). These results were also compared with various relevant literature and guidelines.
