Autor(es): Martins, Vitória Gabriele Rezende Primeiro Orientador: Sales, Juliana de Fátima Primeiro Membro da Banca: Sales, Juliana de Fátima Segundo Membro da Banca: Rodrigues, Arthur Almeida Terceiro Membro da Banca: Silva Júnior, Édio Damásio Abstract: Lettuce (Lactuca sativa L.) is a short-cycle vegetable widely cultivated and sensitive to the presence of environmental contaminants, such as calcium fluoride (CaF₂). The vegetable can exhibit alterations that compromise its development, which can be observed daily or in laboratory analyses. Due to this behavior, lettuce acts as a bioindicator. In this context, the objective was to evaluate the effects of CaF₂ as a possible pollutant on the initial development of Lactuca sativa L., analyzing parameters of germination, root growth, germination speed index (GSI), chlorophyll fluorescence, and leaf anatomical alterations. The experiment was conducted in a completely randomized design, with five concentrations of CaF₂ (0, 5, 10, 15, and 20 mg L⁻¹) and four replicates, distributed in two experimental stages. The results indicated that exposure to calcium fluoride affected physiological and structural parameters of the plants. Changes were observed in the germination process and seed vigor, as well as anatomical modifications in the leaves, characterized by tissue disorganization as CaF₂ concentrations increased. Therefore, CaF₂ at doses from 15 mg L⁻¹ can pose a potential risk to the initial development of the crop, compromising germination, germination speed index, and seedling growth. Thus, Lactuca sativa L., through laboratory analyses and studies, proves to be an efficient and low-cost bioindicator tool.

The central objective is to analyze the gravimetric composition of household waste in Itumbiara to provide a basis for more sustainable public management strategies. The methodology adopted was comprehensive, integrating the survey of historical weighing records, the application of social perception questionnaires with residents, and the execution of gravimetric characterization tests using the quartering method on representative samples from urban collection routes. The study addresses the waste cycle in its entirety, from citizen behavior regarding source segregation to the logistical challenges faced by the municipal administration. By cross-referencing data on organic matter, recyclables, and hazardous waste fractions with the community’s perspective, the research highlights the need for regional and educational management. It is concluded that organic waste is the predominant fraction in the municipality and that recyclable materials account for approximately 21.2% of the sample, indicating the viability of expanding selective collection and supporting waste picker cooperatives.

In this context, the present study aimed to analyze and systematize the procedures required for the environmental licensing process of general grain storage facilities in the municipality of Rio Verde, Goiás, focusing on the legal and environmental compliance of such enterprises. The methodology adopted was based on documentary and bibliographic research, including the analysis of current environmental legislation, applicable technical standards, and regulatory documents issued by the Municipal Department of Environment (SEMMA). The results demonstrated that municipal licensing presents a comprehensive set of technical and administrative requirements, involving different types of environmental permits, as well as the need for continuous compliance with environmental conditions to ensure the conformity of enterprises. The study also identified procedural bottlenecks and the need for greater administrative standardization in order to optimize environmental analysis workflows. It is concluded that environmental licensing constitutes a strategic instrument for environmental planning and management, contributing to the organization of the sector, the reduction of environmental impacts, and the strengthening of municipal environmental governance.

It was necessary to assess the situation of the place, and understand the changes that are necessary to bring about a good alternative. The importance and need for water in general was also an issue addressed, as well as the difference between water and water resource. The restoration of the cerrado, in the case of riparian forests, gallery forests, is something that must be approached in a practical way and of great relevance to the importance of conservation of the biodiversity of the Brazilian cerrado. KEYWORD: spring, water, recovery, restoration of the cerrado.
