Industrial activities generate too much effluents which, if not treated properly, generate pollution and damage to water resources, which makes environmental requirements severest. The project proposes to a dairy industry, specialized in the production of cheese bread, an efficient treatment of effluents, technically and economically viable of its waste generated in the process that is currently launched without treatment in nature, with a high pollutant load characteristic of waste from the dairy industry. For this, bibliographical surveys were carried out on the subject of effluent treatment, application of a questionnaire in the company and the physico-chemical characterization of the generated effluent with the purpose of elaborating the design of the Vermifiltro. Thus, the result of this work is the complete design of the treatment system that was proposed to the industry, composed of the results of laboratory analysis, sizing calculations, low plan of the implantation site, as well as the schematic design of the Vermifiltro. Therefore, Vermifiltro appears as an option to remedy environmental pollution, as well as showing itself as an efficient and economically viable technique in relation to conventional treatments, since the release of tailings in water resources directly affects its quality, changing its characteristics originates and causes in several imbalances, which evidences the necessity of the implantation of a treatment system.
The preservation of the environment is one of the most relevant issues today. In view of new concerns and positive perspectives regarding the adoption of sustainable development policies, it is necessary that environmental education be treated in the daily life of individuals from a young age, thus contributing to the construction of habits and attitudes of preservation of quality of the environment to which they are inserted. This article aims to highlight how the environmental education implanted in the Crê-Ser Foundation in João Monlevade-MG, contributed to raising awareness and awareness among students. For the development of the research, we used data obtained through bibliographical research and methodologically planned meetings at the foundation, where we sought to transmit information in a playful way, from the wheels of conversations and interactive activities. With the data obtained in the foundation it was possible to perceive a cleaner and more organized environment, besides changes of behavior, that contribute to a better quality of life. Environmental Education is effective in training individuals, making them reflect and acquire knowledge about environmental practices and ways of minimizing environmental damage.
Carbendazim is a systemic fungicide used in several countries, particularly in Brazil. However, studies suggest that it is related to the promotion of tumors, endocrine disruption, and toxicity to organisms, among other effects. As a result, carbendazim is not allowed in the United States, Australia, and some European Union countries. Therefore, further studies are necessary to evaluate its effects, and zebrafish is a model routinely used to provide relevant information regarding the acute and long-term effects of xenobiotics. In this way, zebrafish water tank samples (water samples from aquari containing zebrafish) and liver samples from animals exposed to carbendazim at a concentration of 120 μg/L were analyzed by liquid chromatography coupled to high-resolution mass spectrometry, followed by multivariate and univariate statistical analyses, using the metabolomics approach. Our results suggest impairment of lipid metabolism with a consequent increase in intrahepatic lipids and endocrine disruption. Furthermore, the results suggest two endogenous metabolites as potential biomarkers to determine carbendazim exposure. Finally, the present study showed that it is possible to use zebrafish water tank samples to assess the dysregulation of endogenous metabolites to understand biological effects.
O Engenheiros Sem Fronteiras - Núcleo João Monlevade, de caráter extensionista e sem fins lucrativos, tem como objetivo, através da engenharia social, ajudar as comunidades, melhorando a qualidade de vida através da implantação de projetos. Junto a isso, é desenvolvido o perfil do engenheiro consciente, tanto com as questões ambientais, quanto com as sociais. Foram desenvolvidas atividades na Fundação Municipal Crê-Ser, durante o ano de 2018, e o projeto “Aprendendo a Transformar”, em 2019; ambos na cidade de João Monlevade-MG. Os projetos têm gerado bons resultados e alcançado diversas pessoas, entre elas, alunos e funcionários da Universidade do Estado de Minas Gerais – UEMG João Monlevade, e também pessoas das comunidades envolvidas
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
