Abstract: | The aim of this study was to identify possible relationships between biochemical- superoxide dismutase (SOD), glutathione
peroxidase (GPx), thiobarbituric acid reactive substances (TBARS) of mussels (Mytilus galloprovincialis) and chemical (Hg, Cd, Pb, Cr, Cu, Zn, Mn and Fe) contaminants from relatively clean area (Middle Bay) and heavily polluted
area (Inner Bay) of the Izmir Bay. Sampling of mussels was performed in the beginning of May 2004. Mussel digestive glands
have been used for biochemical assays. Trace metal content was determined by atomic absorption spectrophotometer using standard
procedures. Metal contents in mussels collected at polluted site increased compared to the middle part of the bay. While there
was a positive correlation between metals and SOD enzyme activity, there was a negative correlation between metals and GPx
enzyme activity. An increase was observed in SOD enzyme activity and a decrease of GPx enzyme activity at the inner part of
the bay. |
