| Abstract | ||
| In this paper; the concentrations of Pb, Cd, Cr, Zn, Cu, Mn and Fe were determined in the muscle tissues of seven marine and one fresh water fish species. Marine fishes were collected from the Mediterranean sea of the shore of Misurata; while fresh water fishes were collected from Tawarga stream located at about 65 Km west of Misurata according to fish habitat and type of heavy metal itself. Different fish species were collected from different Libyan localities. The results showed that the highest levels of lead, cadmium, chromium, zinc, copper, manganese and iron were found in Bolty (1.64 mg / kg ), Bouri (0.07 mg / kg ), Sardine (0.93 mg / kg), Denis(5.84 mg / kg),Balameat (0.97 mg/kg), Sardine (0.57 mg / kg), and Maghazel (8.61 mg / kg ) fish, respectively. The lowest levels of lead, cadmium , chromium , zinc and copper, were found in Balameat, (0.71 mg / kg ), Sardine (0.03 mg / kg ),Maghazel (0.06 mg / kg ),Bolty(2.1 mg / kg ) and Bolty (0.46 mg / kg ) fish , respectively. With regard to manganese, the lowest levels were observed in Kawally (0.25 mg / kg ), and Maghazel (0.24 mg / kg ), whereas Denis and Tuna fish showed lowest levels of iron (1.17 mg / kg ). | ||
