ESTIMATION OF THE HEAVY METALS IN THE POISONOUS RABBIT FISH LOCATED ON THE SHORES OF DERNA LIBYA

Abstract

The concentration of metals in the animal organs can be a reasonable guide to public health standards and for the organism condition as well. Each environmental pollutant, and metals are of particular concern, to their potential toxic effect and ability to bio accumulate in aquatic ecosystems. The present work was carried out to compare some heavy metals of the rabbit fishes in Derna city. In the present study the concentration of four heavy metals; lead (Pb), Chromium (Cr), cadmium (Cd) and Nickel (Ni), were estimated in Fish fin, liver tissue, eyse and skin of rabbitfish species; Euthynnus all the Libyan coast plays an important role in terms of biodiversity and productivity of Mediterranean marine ecosystem. This study is outlined to survey potential dangers for human populaces through angle admissions. It enhances the information about anthropogenic impacts in Derna (Libya).  The levels of lead (Pb), cadmium (Cd), Chromium (Cr) and Nickel (Ni), in Fish fin, liver tissue, eyes, meat and skin of rabbitfish. The results appeared that impressive distinction in metal concentrations among fish organs. The highest concentrations of lead (Pb) in the fish fin. While, Nickel (Ni) the lowest concentration in the skin.
