The use of biomarkers in pollution monitoring studies is well-established, but the type of biomarkers which are suitable for use under oxidative stress conditions in this field is not well-known. In this study, biomarker re-sponses to Na+, K+-ATPase, glutathione (GSH) and thio-barbituric acid reactive substances (TBARS) were exam-ined, in the presence of water pollution caused by Aeshna affinis, on odonata larvae collected from Sarıçay, some parts of which are subject to domestic, industrial and agricultural pollution. As a result of the study, a signifi-cant increase was observed inGSH and TBARS levels in Aeshna affinis individuals collected from the polluted area compared with the living organisms collected from the unpolluted area (p<0.05) whereas a considerable inhibi-tion of Na+, K+-ATPase enzyme activity was discovered (p<0.05). The findings of the study suggest that the pol-luted area of Sarıçay is under oxidative stress from water pollution by Aeshna affinis, which is, however, tolerated by an antioxidant defense system. In addition, the bio-markers used in this study appear to be suitable indicators to see the effects of water pollution on living organisms.
