Abstract
This study was conducted to evaluate the adverse effects of atrazine on hematology, biochemistry and genotoxicity of snow trout (Schizothorax plagiostomus). Almost all treated groups presented considerably (P < 0.05) lesser values of hematocrit, hemoglobin, WBC, RBC, MCH, MCHC, monocytes and lymphocytes while significantly higher values of HCT and platelets are observed. A Significant decrease is observed in sodium, calcium, potassium, phosphorous, triglycerides, creatinine, urea, and total protein contents whereas, a significant increase is observed in cholesterol and glucose level. Significant (P < 0.05) alterations are observed in enzyme activities of all treated groups. DNA damage was observed at the concentrations (2-4 ppm). Results showed that Comet assay is reliable for evaluating the toxicity and is helpful in environmental monitoring programs.
