Abstract

The project aims to provide the student the basic concepts involved in Ecotoxicology and Environmental Mutagenesis, in order to prepare him for graduate school, the development of bioassays with a major waste used in the cultivation of cane sugar (vinasse) focus of this study. The vinasse produced by several countries as a byproduct of agricultural activity, has as main raw materials to cane sugar, oranges, corn and beets. There are different alternatives for its reuse, being the most used fertigation in plantations of sugar cane, which increases the productivity of the crop and is inexpensive. However, its increasing use as a fertilizer has generated great concern, since its effects have caused both financial and environmental losses, primarily related to non-target organisms. To estimate the effect which the organisms are exposed when in contact with these substances can perform chemical analyzes associated with bioassays. The use of Allium cepa as a test organism has advantages, such as ease of handling, low cost, rapid root growth, high availability and chromosomes in number and large in size. Thus, this project proposes to conduct analyzes involving two different types of vinasse, the cane-sugar and the orange, using the A. cepa test system to evaluate the possible toxic effects, cytotoxic, genotoxic and mutagenic such effluent used in agricultural areas, especially in the culture of cane sugar, can cause.
