Abstract

In recent years, environmental issues have been incorporated into the educational curriculum, being addressed by several subjects as a "cross-cutting theme". Environmental pollution is an aspect most frequently dealt with by Chemistry, to characterize the origin and structure of pollutants. Little attention has been given to the topics related to Toxicology, and to the methods of its evaluation. The present work has as a didactic proposal to approach bioindication concepts using a plant organism by means of the Allium cepa test, which has characteristics that make its implementation suitable for classroom dynamics, allowing students to evaluate the ecotoxicity and genotoxicity of chemical substances or mixtures. This activity is a good trigger to approach the environmental issue from all areas, in addition to introducing the concepts of bioindicator and genetic toxicology, which are not currently incorporated in education programs and are part of everyday life.
