| Abstract | ||||
| The herbicide atrazine is currently the most popular in the world's agriculture. The aim of the current study was to assess the toxicity of the commercial herbicide atrazine [Gesaprim] and its divers effects on haematological and biochemical indices in Nile Tilapia [Oreochromis niloticus]. By using probit analysis, the atrazine's 96-hour LC50 was determined [29.889 mg/L]. Fish were subjected to atrazine at varying concentrations [1/2 LC50=14.945 mg/l, 1/3 LC50=9.96 mg/l, 1/5 LC50 = 5.978, and 1/10 =2.989 mg/l] for a month in the study on chronic toxicity. WBC, MCHC, MCH, cholesterol, triglycerides, creatinine, uric acid, glucose, AST, and ALT demonstrated a significant increase with increasing concentrations and days [P<0.05], whereas RBCs, Hb, Ht, MCV, protein, albumin, and globulin demonstrated a significant decrease [P<0.05]. Hence, the study has demonstrated that atrazine exposure is hazardous to O. niloticus. Therefore, the use of the herbicide atrazine must be at a minimum level and these parameters can be used as effective guidelines for the toxic level indices for farmed tilapia fish. | ||||
