Abstract

Heavy metal concentrations Lead Pb, Cadmium Cd, and Iron Fe) were determined in the muscles, liver, and skin of Mugil cephalus (Mugilidae) in Tobrukharbor, eastern Libya. The results revealed that the concentration of Pb reached high levels in the skin, while recorded low levels in the liver tissues. Pb level in the liver, skin, and muscle tissues of Mugil cephalus was more than the international standards. The high concentration of Fe recorded in the liver tissue, while, recorded its low concentration in the skin. Also, maximum levels of Cd were detected in the liver, while it attained their low level in the muscles. Generally, the level of Pb and Fe in muscle tissues of Mugil cephalus was more than the international standard and the level of Cd in muscle tissue of Mugil cephalus was lower than the general standard. On the other hand, heavy metals concentration levels in seawaterofTobrukharbor, eastern Libya, exhibited a high level for Fe then Pb comparing to the level of Cd. The relationship between size and weight of Mugil cephalus and the levels of each metal was studied
