    Aquatic ecosystems can be considered as an indicator of health in both animals and humans. In this study, heavy metal levels (Cd, Co, Ni, Cu, Fe, Se, Zn, Cr, Mn and As) were determined with ICP-OES in some tissues (muscle, liver, gill, gonad and kidney) of Cyprinus carpio L., 1758 living in Bafra fish lakes. In addition, antioxidant enzyme activities (CAT, GSH-Px and SOD), MDA levels, blood biochemical and hematological parameters were studied. All heavy metal results were lower than the limits prescribed in European Communities and the Turkish Food Codex in muscle tissue, except arsenic. Moreover, some heavy metal levels (Cd, Zn) were higher in other tissues (liver, kidney, gill and gonad) as well. The changes in the other parameters of study were also discussed in terms of heavy metal levels. In conclusion, it is possible that heavy metals levels may increase in fishes living in Bafra fish lakes because of both domestic waste water and agricultural activities. Therefore, we suggest that heavy metal levels should be monitored regularly. © Medwell Journals, 2010.

    Evaluation of metal accumulation,oxidative stress biochemical and hematological parameters in Sander lucioperca L.,1758 from Bafra (Samsun) Fish Lakes
    (2011) Doğru, Mehmet İlker; Örün, İbrahim; Kocagün Doğru, Arzu; Kandemir, Şevket; Altaş, Levent; Erdoğan, Kenan; Örün, Gülnihal; Polat, Nazmi
    Fish, generally accumulate contaminants from aquatic ecosystems, have been largely used in environmental researches. In this study, heavy metal levels (Cd, Co, Ni, Cu, Fe, Se, Zn, Cr, Mn and As) were determined with ICPOES in some tissues (muscle, liver, gill, gonad and kidney) of Sander lucioperca L., 1758 living in Bafra Fish Lakes. In addition, antioxidant enzyme activities (CAT, GSH-Px and SOD), MDA levels, blood biochemical and hematological parameters were studied. Generally heavy metal levels in tissues were lower than the limits prescribed in European Communities, the Turkish Food Codex (TFC) and the literature. But, we have found high levels of As, Cd and Zn in some tissues (muscle, gill, kidney and gonad). The changes in the other parameters of our study were also discussed in terms of heavy metal levels. In conclusion, it is possible that heavy metals levels may increase in fishes living in Bafra Fish Lakes in the future via anthropogenic sources. Therefore, we suggest that heavy metal levels should be monitored regularly. © by PSP.

    The investigation of heavy metal accumulation, oxidative status and hematological parameters in common rudd, Scardinius erythrophthahnus (L. 1758) from Bafra Fish Lakes
    (2014) Doğru Kocagün, Arzu; Kandemir, Şevket; Örün, İbrahim; Doğru, Mehmet İlker; Altaş, Levent; Erdo?an, Kenan; Örün, Gülnihal; Polat, Nazmi
    The use offish in environmental monitoring has become increasingly important in recent years. In the current study, heavy metal levels (Cd, Co, Ni, Cu, Fe, Se, Zn, Cr, Mn and As) were determined with ICP-OES in some tissues (muscle, liver, gill, gonad and kidney) of Scardinius erythrophtkalmus L., 1758 from Bafra fish lakes. In addition, antioxidant enzyme activities (CAT, GSH-Px and SOD), Malondialdehyde (MDA) levels and hematological parameters were investigated. Heavy metal results were compared to European Communities, the Turkish Food Codes (TFC) and the literature. As, Cd and Zn levels in some tissues were determined higher than the limits. In conclusion, heavy metal levels in Bafra fish lakes may increase via anthropogenic source in the future. Therefore, heavy metal levels of Bafra fish lakes should be checked and oxidative stress of the fish controlled regularly for food safety and environmental pollutions.
