A biomonitoring study: Using the biomarkers in Cyprinus carpio for the evaluation of water pollution in Sapanca lake (Sakarya, Turkey)

This study aims to determine the toxic effects of heavy metal pollution on carp (Cyprinus carpio) in Sapanca Lake by biochemical and histological analyses. For this reason, fish water samples were taken from lake 2015. Heavy (Cu, Fe, Zn, Pb, Cd) analyzes column tissues (muscle, liver, gill) determined ICP-OES. CAT, GSH MDA levels, which are oxidative stress bioindicators tissues, measured spectrophotometric methods. Histopathological findings Hematoxylin-Eosin staining. As a result, concentrations as Fe > Zn Pb Cu Cd. The accumulation Cu, Cd liver gill muscle, was muscle. CAT activity, level changed with temperature. General signs destruction observed fish. Necrotic conditions hepatocytes observed. In conclusion, presence histopathological suggests that is not only affected metals but also other pollutants.
