  Toxicity assessment of advanced biological wastewater treatment plant effluent by integrated biomarker response in zebra mussels (Dreissenapolymorpha)

  Serdar, Osman; Ketenalp, Zozan; Yildirim, Nuran Cikcikoglu

  In this study, zebra mussels (Dreissena polymorpha) were exposed to advanced biological wastewater treatment plant effluent (ABWTPE) for 96 h. At the end of the 96th hour, antioxidant parameters such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), glutathione S-transferase (GST), malondialdehyde (MDA) and glutathione (GSH) were examined. The objective of the study was to identify biomarkers that are useful for assessing the potential toxic effects of ABWTPE in freshwater environments. We observed an increase in GPX, SOD activity and MDA levels, and a decrease in CAT, GST activity and GSH levels. The results obtained in our study showed that the measured biochemical parameters (GSH, MDA, SOD, CAT, GPX and GST) are useful biomarkers in determining the possible toxicity of ABWTPE in aquatic environments.

  The aim of this work was to determine the seasonal changes in the activities of selected biomarkers in Capoeta umbla (Heckel, 1843) caught from Uzuncayir Dam Lake (Tunceli, Turkey) and to evaluate the effects of environmental factors on these activities. Fish were sampled on seasonal basis, and superoxide dismutase, catalase, glutathione peroxidase activities and levels of glutathione and malondialdehyde in gills were determined. Significant variations of oxidative stress biomarkers were observed between seasons and sites. The results of this study show that seasonal variations of oxidative stress responses and lipid peroxidation in gills of C. umbla are sensitive to the contaminants present in water of Uzuncayir Dam Lake and selected parameters are in valuable biomarkers for monitoring of water systems, since they give an early warning signal of effects of xenobiotics on aquatic organisms at molecular levels which help to prevent their effects at organismal level.
