title: Effect of zeta-cypermethrin on common carp (Cyprinus carpio L.).
abstract: OBJECTIVE
  The aim of this study was to assess the effect of pesticide Fury 10 EW, containing zeta-cypermethrin 100 g.l-1, on common carp (Cyprinus carpio L.).
  
  
  METHODS
  The toxicity tests were performed on common carp according to OECD 203 methodologies. The common carp were exposed to Fury 10 EW at concentrations, 5, 7, 10, 50 and 100 μg.l-1 for 96 h and compared to common carp in a non-treated control group. Acute toxicity tests were detected value 96hLC50=13.8 µg.l-1. On the basis of the results was assessed the effect on the hematological profile, oxidative stress parameters, and antioxidants biomarkers in tissues, in another acute test.
  
  
  RESULTS
  The observed 96hLC50 value of Fury 10 EW was 13.8 μg.l-1. A significantly lower large lymphocyte and monocyte count, and a significantly greater number of segmented eosinophil granulocyte and higher hematocrit was found in the pesticide-exposed common carp compared to controls. Oxidative damage was not detected in the experimental common carp, however there were significant differences from control in superoxide dismutase (SOD), catalase (CAT) and glutathione reductase (GR) in tissue after acute exposure to 13.8 μg.l-1 Fury 10 EW.
  
  
  CONCLUSIONS
  Zeta-cypermethrin as Fury 10 EW was classified as a substance highly toxic to fish. The hematological profile well oxidative stress parameters and antioxidant defensive systems provide important information about the internal environment of organisms. There is a lack of experimental results about the effects of zeta-cypermethrin on fish in the literature.
