(Universidade Federal do Pará, 2016-05-02) RIBEIRO, Dayane Negrão Carvalho; ALMEIDA, Ana Cristina Pimentel Carneiro de; http://lattes.cnpq.br/1265908866509687
Water is a topic commonly treated in the teaching of science, but a resource availability scenario lacks discussions to training for citizenship through the recognition of scientific and technological issues surrounding access to the use and preservation of human life. In this scenario, this study sought to determine how the proposed theme "Water for Human Consumption" can influence the training for citizenship of elementary school students of a school of public schools in the city of Abaetetuba, generating in this context two thematic booklets on the proposal, namely: a thematic booklet for students and a booklet with activity suggestions for the teacher. The used theoretical foundation hás two sections. The first incorporates the approach in Science, Technology, Society and Environment and his notes to improve the teaching of science through teaching by theme based on three pedagogical moments of Delizoicov, Angotti and Pernambuco (2011), from the context of situations students in order to involve them actively in the search for solutions through diversified activities. In the second section I write about scientific knowledge related to water and its influence on the teaching of science. The research environment was formed through a short course, attended by eleven students of the sixth grade of elementary school as research subjects, as well as teacher-researcher. The action research was the methodological option chosen in this study to collect data, which are analyzed in light of the interpretative analysis of Creswell (2007). The data showed that the subject worked in the Science approach, Technology, Society and Environment enables students to recognize the problems of their reality, allowing its insertion in the search for solutions, and also shows the importance of working everyday reality, paying attention the difficulties of the students to express themselves orally and in writing. As for the teacher researcher, this study showed how reflective practice was important for the conduct of short course activities. Regarding the product of this work, the two primers for use in teaching-learning situation, I consider it possible that the treatment of the subject, because aroused the interest of students to continue the activities culminating in presentations to the school community. And yet, there was the drafting of a letter by students with proposals to solve specific problems that was sent to the school towards improving knowledge about the problems and possible solutions observed by students in their school environment, with regard to access to water for human consumption

Avaliação de riscos aplicada como metodologia de controle e segurança da qualidade da água no sistema de abastecimento de Belém - PA
(Universidade Federal do Pará, 2016-03-08) ARAÚJO JUNIOR, Antonio Jorge Silva; TEIXEIRA, Luiza Carla Girard Mendes; http://lattes.cnpq.br/9773700229115395
This study aims to use the risk assessment approach FMEA as control and safety methodology of water quality in Belém supply system. During the monitoring period were determined indicators free residual chlorine, turbidity, apparent color, pH, fluoride, total iron, total coliforms and E. coli. Collections and analyzes were performed in 46 points of Belém supplies central zone, including water treatment plants, reservoirs drop in the sectors and in the supply network. Each set of data received descriptive statistical analysis, outlier removal and passed the Kruskal Wallis test to determine significant differences between indicators of different supply sectors. It was found that the 3680 measurements, 706 showed no compliance with potability standards (BRASIL, 2011), of which 582 were in the supply network, 92 on the reservoirs drop in the sectors and 32 at treatment plants. The FMEA methodology was applied to all the analyzed indicators, and the points were divided into three groups: REDE, DRS and ETA’s. For the REDE group were identified 18 points of moderate risk and 18 points high risk. For the DRS group and ETA’s all the points were moderate risk. In this research there was no occurrence of despicable risk and critical. The indicators fluoride, total coliforms and E. coli were the most influential, accounting for approximately 15% in the risk weights. However, fluoride indicator contributes to increase the category of risk, because it showed 100% nonconformities with the fluor standards (BRASIL, 1975) in every point. After the categorization of risk, were prepared two maps, one with points and other with contours, representing the risks related to the quality of water for each one of the studied points. The contoured map was best represented the risk, as it presented more comprehensive information.

Avaliação do desempenho ambiental e racionalização do consumo de água no segmento industrial de produção de bebidas
(2013-12) CAVALCANTE, Luciana Miranda; MACHADO, Luiza Carla Girard Teixeira; LIMA, Aline Maria Meiguins de
The Amazon region, with a high hydric potential, has attracted companies that require significant volumes of water; therefore, control instruments are necessary to monitor this trend. In this study, the degree of rationing of water use by beverage industries in Para state and the behavior of the sector are discussed. The subjects' variables were classified according to four study dimensions (environmental management, water management, wastewater management, and advanced measures for rationing) that compose the rationing level of water industrial management. The independent variables were associated by size, industry type, packaging used, water availability and the economic value of water. The data show that beverage production has a significant water footprint, higher than 15,250 m3/day, and that small industries have the highest relative consumptions (more than 7 L of water/beverage L). In general, the sector does not ration significant quantities of water; a better result was obtained for water management. However, some more efficient measures could be adopted, especially with regard to water reuse in cooling towers. Analysis of the variables shows that the rationing level is directly dependent on the size of the industry and on the type of product. Consumption tends to be lavish. In response to this situation, public policies should be prioritized to determine the water footprint of products and environmental cost should be considered in the overall cost of production.

A Dinâmica das organizações turísticas e o consumo de água em São Luis (MA) e Belém (PA)
(Universidade Federal do Pará, 2018) GOMES, Eduardo Lima dos Santos; SIMONIAN, Ligia Terezinha Lopes; http://lattes.cnpq.br/6620574987436911
This thesis discusses the limits and possibilities of the natural water resource to become an opportunity of competitive advantage in the tourism sector, particularly in tourist accommodation organizations. From this perspective, questions arise about the place and role of these tourist organizations in the political and socioenvironmental water scenario. Therefore, the objective was to analyze the extent to which the implications of water consumption position the tourist organizations of accommodation, in São Luís (MA) and Belém (PA), the formulation of sustainability strategies for eco-innovation. For this purpose, the study is based on a review of the literature on theories that explain economic development from a Schumpeterian and Neoschumpeterian view, as well as the approach to sustainable development on the path to water sustainability in the tourism sector. Based on the literature review, a hypothesis was suggested and tested in the empirical part of the thesis through an analysis of the dynamics of tourism organizations concerning the implications of water consumption in these two amazonian cities in question. The methodology had the interdisciplinary orientation between economics and anthropology, through the development of qualitative research of an exploratory, descriptive and explanatory type with the procedure of the case study of multiple character. For this, the technique of semi-structured interview with the application of the instrument form was used. This analysis is based on data obtained through interviews-formulary aimed at chief executives of the tourism organizations and water companies. The results show that the strategies adopted by tourism organizations are merely palliative measures directly proportional to the optimization of financial costs. With this, the water issue, especially in the face of the possibilities of a growing water crisis, becomes important for research and, in the tourism sector, water can be an opportunity for sustainability strategy for eco-innovation, promoting the responsible and smart tourism.
