RESUMO:

The Brazilian semiarid has several characteristics that make it an area of great impact for environmental quality studies, from studies on water scarcity to problems related to natural pollution. Thus, in view of the adversities encountered in this region, this study aims to analyze the patterns and genotoxic effects that can cause contamination by radioisotopes and other natural pollutants, using endemic and Saxon lizard species occurring in the Caatinga of Rio Grande do Norte, as biomonitors. , as well as conduct a survey of current knowledge about the toxicity of environmental pollutants in the world's lizard species. To this end, a review of available knowledge in the last ten years related to pollutants in lizards was performed. In addition, collections were performed on two species of endemic and Saxon lizards in three areas of the RN, such as soil collection, water and strip emissions, to evaluate mutagenic effects that affect nature and other pollutants that may be in use. cause these animals. For the literature review study, it was observed that the contaminants directly contributed to several genotoxic, histopathological effects, oxidative stress and in many cases, bioaccumulation of metals in exposed animals. However, it has been observed that there is still research to describe the best real effects of various contaminants on lizards. The second part of the dissertation is in progress, where the data are considered of great relevance to broaden the knowledge of this subject in environmental studies.
