| Abstract | In this study, in aquatic environments negative effects which may occur in order to have information about, the acute toxicity Bentazone (Herbicide) and Chlorpyrifos (Insecticide) which widely used in agriculture in Cukurova Region has been researched into larvae Oreochromis niloticus (L., 1754). In this study, the test fish O. niloticus larvae (average weight 1.21±0.52 g, average length 4.29±0.2 cm) were obtained from the Cukurova University Fisheries Faculty Freshwater Fish Research and Application Station. In the experiment, five different concentrations together with the control group were used 2 test series. In the present study, methods of bioassay test which static method has been applied. The study was carried out under laboratory conditions at 25±2 o C. The results has been estimated with the dose-response data were fitted a log-logistic model by using R 3.0 statistical computation environment and DRC library. The 24-h acute LC50 values were calculated. According to the results, acute toxic effects researched Bentazone (Herbicide) and Chlorpyrifos (Insecticide) the 24-h LC50 acute toxic lethal concentration values for Oreochromis niloticus (L., 1754) larvae were calculated Bentazone (Herbicide) LC50 14.86±0.19 mgl -1 and Chlorpyrifos (Insecticide) LC50 0.40±0.02 mgl -1 . |
