Adverse effects of atrazine on blood parameters, biochemical profile and genotoxicity of snow trout (Schizothorax plagiostomus)

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.
