Title: Acute toxicity of atrazine to Oreochromis niloticus fingerlings
Abstract: Acute toxicity of atrazine to Oreochromis niloticus was undertaken to find the lethal concentration (LC) 50 of atrazine using fingerlings. Different concentrations were prepared in mg/L. There were six different concentrations with a control and each treatment was replicated three times. A total number of twenty-one aquaria were used. The highest concentration was 30mg/L. Ten test organisms were used in each aquarium. At 24, 48, 72 and 96 hours there were LC 50 of 15.6mg/L, 14mg/L, 11mg/L and 9.4, respectively. At 24, 48, 72 and 96 hours there were mean survivals of 49.0%, 34.3%, 28.6% and 28.1%, respectively
