【 摘 要 】

Water pollution is a serious environmental problem. In Rondinha, Rio Grande do Sul, on a small area planted with tobacco, it has been using organophosphates pesticides. The purpose of this study was to evaluate the organophosphates pesticides contamination of the superficial water in this municipality. The samples collected in fifteen places were evaluated by the method of organophosphates acethylcolinestherase inhibition. In five samples the organophosphates levels were above the limit established by CONAMA, indicating the necessity of arrangements that allow reducing the risk of the population and the environment contamination.
