Item Análise da qualidade da água da Laguna Manguaba do Município de Marechal Deodoro - AL(2022-05-02) Rocha, Elenice Melo da; Silva, Dário Luiz Nicácio; http://lattes.cnpq.br/1506941694331741; Bastos, Adelmo Lima; http://lattes.cnpq.br/6125212623471598; Gama, José Aparecido da Silva; http://lattes.cnpq.br/7413041757828843The Lagoon Manguaba de Marechal Deodoro, is of great economic value for many families from Deodoro, as it produces a wide variety of aquatic organisms, such as: fish, shellfish and molluscs, which are a source of income and also food for the families of fishermen in the region who depend solely and exclusively on fishing, and have no other means to guarantee the sustenance and survival of their family members. The lagoon has a scenario of exclusive scenic beauty, where we can see on one side a beautiful green landscape composed of a beautiful and extensive mangrove and on the other side a beautiful lagoon edge, with a sports and leisure area, restaurants and snack bars serving dishes of typical foods, made with fish from the Manguaba lagoon, attracting tourists and visitors from various places. These restaurants generate direct and indirect jobs, however, they contribute negatively to the pollution of the lagoon, dumping their contaminating effluents directly into the water, without any form of treatment. There are several sewage and/or filthy tongues along the lagoon edge, being released directly into the Manguaba lagoon, not only from restaurants and bars, but also from other neighborhoods in the municipality. The presence of oil in the discharge of these effluents is notorious. It is also noted the disposal of household waste in the water bodies of the Laguna, such as: Tires, iron, wood, plastic (food packaging and bags), glass (beverage bottles and shards) that are discarded by the population that lives there. passes, or often, through the action of the wind. The objective of this work is this, to analyze, using instruments accessible to the population, environmental parameters that indicate water quality, trying to relate variations in these parameters to sudden changes in water quality in Laguna Manguaba, on the edge of the municipality of Marechal Deodoro.Item Análise da qualidade da água e percepção dos moradores do Conjunto Olival Tenório Costa em Campo Alegre - AL(2023-05-08) Silva, Celso Felipe da; Silva, Dário Luiz Nicácio; http://lattes.cnpq.br/1506941694331741; Bastos, Adelmo Lima; http://lattes.cnpq.br/6125212623471598; Gama, José Aparecido da Silva; http://lattes.cnpq.br/7413041757828843Water is a natural resource of great importance for the maintenance of human life and a public good, as described in art. 1 of Law 9433/97 which provides for the National Water Resources Policy. The importance of water is not only related to its functions in nature, but the role it has in health, economy and quality of human life. Water quality is an indispensable aspect when it comes to its main uses, especially for purposes such as human supply and the supply system must favor this aspect. With this, the objective of this study was to carry out an analysis of the water quality of the Conjunto Olival Tenório Costa in Campo Alegre, Alagoas, and to evaluate the functioning of the local supply system through the perception of the local residents. During a period of four weeks, 500ml of water were collected in the eight blocks of the complex, totaling 32 samples in the end, where the physical-chemical analyzes were carried out. In possession of the results obtained through the analyses, the potality standard established by the legislation was detected. In all analyses, it was possible to observe that only in the analysis of the fourth week a pH of 6 was obtained, whereas in the others, below, the values were lower, also having oscillations between the results. Regarding the presence of color, it was found that there was no presence of free residual chlorine in any of the possible analyses. After carrying out the physicalchemical analyzes of the water and noticing some irregularities in the face of the legislation, the objective was also to evaluate the perception of the local residents about the quality of the water and the supply system through a virtual interview via electronic means, where 120 residents participated, and of this number, 75.5% were female. Regarding the quality of the taste of the water that arrives at the residences, 45.8% classified the taste of the water as bad, when asked if the handlers had already witnessed any alteration in the water, 76.7% of them said yes. And finally, 54.2% of those approved classified the supply system as bad. Finally, it is concluded that the water distributed to the population of Conjunto Olival Tenório Costa has already interfered in the issue of health of the inhabitants, and the responsible authority must remain vigilant to possible future health projects.Item Avaliação da qualidade da água das nascentes utilizada pelos moradores do povoado brejo dos vieira - União dos Palmares-AL(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-03-10) Silva, Eri Johnson Correia da; Silva, Dário Luiz Nicácio; http://lattes.cnpq.br/1506941694331741; Bastos, Adelmo Lima; https://orcid.org/0000-0001-6186-8856; http://lattes.cnpq.br/6125212623471598; Gama, José Aparecido da Silva; https://orcid.org/0000-0002-9082-6564; http://lattes.cnpq.br/7413041757828843Water is a natural resource essential for the maintenance of nature and its ecosystems, highlighting its role in agriculture, industry, energy generation and preservation of the health of living beings. In Brazil, water analysis is regulated by Ordinance No. 2,914/2011 of the Ministry of Health, establishing permitted limits for human consumption. Many rural springs lack appropriate treatment, presenting high levels of contamination by pesticides, heavy metals and other pollutants. This study analyzed water from springs in the village of Brejo dos Vieiras, a rural area of the municipality of União dos Palmares in Alagoas, aiming to identify the quality of water in the region, proposing measures for the preservation and recovery of water resources used by the local population. The methodology of the National Health Foundation was adopted for collection and physical-chemical analysis of the samples. The parameters analyzed were: Hydrogen Potential (pH), Electrical Conductivity (EC), Dissolved Oxygen (DO) and presence of Chlorine, measured at 25oC. The analyses demonstrate fluctuations in pH, EC, DO and chlorine values among the different springs over time, which can be justified by the biogeochemical characteristics of the aquifers analyzed. The values obtained were in accordance with the standards established in Ordinance 2,914/2011; in Consolidation Ordinance No. 5/2017 and in CONAMA resolution No. 357/2005, suggesting that the water supplying the rural properties studied is within potability standards. However, it is crucial to carry out new long-term studies that allow a careful assessment of the quality of the water consumed in the region. There were no complaints regarding the supply (quantity) and quality of the water consumed, indicating efficient control and balanced distribution of water resources in the village. It is essential to emphasize that environmental and anthropogenic factors can cause changes in the quality standards of the springs. It is essential that the community maintains constant vigilance and preserves these water sources, ensuring the availability and health of these resources for future generations of the Brejo dos Vieras Village.Item Avaliação do comportamento térmico de resíduos orgânicos de feira livre compostado em composteira caseira – IFAL(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-05-17) Lins, Raquel Cavalcante; Silva, Dário Luiz Nicácio; http://lattes.cnpq.br/1506941694331741; Gama, José Aparecido da Silva; http://lattes.cnpq.br/7413041757828843; Dias, Sheyla Karine Barbosa de Macêdo; http://lattes.cnpq.br/2777322313238567The composting of vegetable waste is considered a low cost alternative when compared to the disposal of organic waste in landfills or in inappropriate sites. However, there is a lack of research that can make the composting process feasible, given the great variety of organic waste produced, as well as the awareness of society in separating and correctly disposing of solid waste. In this sense, the present work aimed to evaluate the behavior of temperature between two treatments, containing organic waste (fruits and vegetables) and tanned sawdust, in different concentrations of material rich in carbon (tanned sawdust), until the mesophilic phase of cooling, using two compositions of different organic materials, in two home composting tanks for each composition. The results obtained from the thermal behavior of home composting, indicated similar results, from the beginning to the end of the composting, with temperature ranges that did not exceed 50°C, where the composters 1AGM and 2AGM, remained at temperatures of 27 to 34°C and the composters 3AM and 4AM with similar ranges of 28 to 33°C, which may be associated with the interference of external factors (wind and rain) and the volume of organic material composted.Item Construção e caracterização de um dessalinizador solar usando tecnologias socioambientais em Marechal Deodoro-AL(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-04-27) Santos, Thiago dos; Silva, Dário Luiz Nicácio; http://lattes.cnpq.br/1506941694331741; Gama, José Aparecido da Silva; http://lattes.cnpq.br/7413041757828843; Almeida, Glaudistone Ferreira de; http://lattes.cnpq.br/2765594406920221Water scarcity is a problem that has been worrying the world, considering that water is a necessary good for the survival of all life on earth. Brazil is a privileged country in terms of the abundance of this good, but its poor distribution ended up creating a problem for part of the Northeast region of the country, which suffers from long droughts and irregular rainfall during the year, and which is supplied with water from cisterns or water from artesian wells. Bearing in mind that these waters do not have ideal potability for consumption due to their high salinity level, there was a need to find viable solutions for residents of the northeastern semi-arid region. In this way, a solar desalination plant was built using materials from construction waste, and improvements were made to improve its efficiency. The desalinator presented excellent results regarding water treatment, reducing by more than 99% of the total solids present in the water, and with efficiency of up to 53.33% of desalinated water, being 32.81% more efficient than the results obtained in a study used as a reference.Item Perfil socioeconômico e sensibilização ambiental dos agricultores familiares do Assentamento Quinta da Serra no município de Viçosa-AL(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-07-26) Hora, Sivaldo Araujo da; Silva, Dário Luiz Nicácio; http://lattes.cnpq.br/1506941694331741; Gama, José Aparecido da Silva; http://lattes.cnpq.br/7413041757828843; Bastos, Adelmo Lima; http://lattes.cnpq.br/6125212623471598Unemployment and the increase of social inequalities have become a worldwide problem revealing that the capitalist production mode is outdated. The present work aimed to evaluate the socioeconomic profile and environmental awareness of family farmers of the Quinta da Serra Settlement in the municipality of Viçosa - AL, through the data obtained through the application of a structured interview where the participants informed about their socioeconomic aspects and environmental awareness. With the data obtained, the reality was traced for knowledge of the profile of these farmers facing these issues, because it is known that after unemployment, many of these workers are without work options to acquire family income. The results found indicate that these farmers have precarious social, economic, and human conditions, but they are all aware of the relevance of their profession for family farming. Without burning, deforestation, growing food without using pesticides, they contribute a lot to the production of healthy food in the municipality of Viçosa - AL. In view of this, it is possible to notice in the data achieved, that despite the social and economic complexity, the profession of family farmer has not been a choice but a matter of survival, in which this working class needs more attention from public authorities and society. Thus, we conclude that it is necessary to develop public policies and search for alternatives to improve the farming systems of the settlement under study, and to create projects that optimize the management of agriculture in the settlement, as well as the development of permanent educational campaigns, training of farmers so that they are treated with the same rights and duties as other workers.
