Abstract
Diazinon is a highly-consumed organophosphate pesticide. This poison can reach to the aquatic ecosystems and has negative effects of aquatics and finally humans. At the present study, effects of 0.5, 1 and 1.5 ppm diazinon on hematological parameters (Hb, HCT, RBC, WBC, MCV, MCH, MCHC, lymphocyte, monocyte, neutrophil and eosinophil count) of the C. damascina were examined. The blood samples were collected at 1, 5 and 9 days after exposure to the poison. HB, HCT, RBC, WBC, lymphocyte counts of the fished exposed to the poison decreased compared to those received no poison. In contrast, diazinon increased the neutrophil count. There was no significant difference in MCV, MCH and MCHC between fishes received poison and the control group. In conclusion, hematological parameters of C. damascina are suitable indicators of diazinon.
