Heavy Metal Levels in tow Species of Fish Gray Mullet (البوري الرمادي)and Scomber. Trachurus (الساورو) Captured from Western Black Sea Turkey

Abstract

In this study Heavy metals concentrations cadmium (Cd), zinc (Zn), copper(Cu), iron (Fe), nickel (Ni), lead (Pd) and manganese (Mn) were determined in two species of fish Gray Mullet ( يروبلا يدامرلا ) and Scomber. Trachurus, the samples were collected from Western Black Sea Turkey , After performing the n(ورواسلا ) ecessary laboratory analysis and statistical analysis the results showed that there were no significant differences between two study fish in Zn , Ni, Mn ,Pb, where the value of the observed level of significance was (p>0.05), there were significant differences between the study fish in Cd, Fe, Cu, where the value of the observed level of significance was (p<0.05), The results of the heavy metal analysis no significant differences between seasons in Cu, Mn, where the value of the observed level of significance was (p>0.05), there were significant differences between seasons in Zn , Ni, Cd, Fe, Pb where the value of the observed level of significance was (p<0.05), it can be said that heavy metal pollution in the Western Black Sea Turkey has not reached a dangerous leveles yet, aims of the study Extent of seasonal accumulation of heavy metals in the studied fish and Comparison and analysis of heavy metals in sediment and economic fish species in western Black Sea coast. Finally, it is highly recommended that similar pollution studies should be carried out at regular intervals and reported routinely to the competent authorities.
