(Universidade Federal do Pará, 1995-10-31) BENVENUTI, Sara Maria Pinotti; RAMOS, José Francisco da Fonseca; http://lattes.cnpq.br/8189651755374537
The aluminum industry is considered one of the main sources of industrial contamination by fluoride, which generates atmospheric pollution. In this research, a quantitative assessment of the distribution of fluoride in the various environmental compartments in the area of influence of the ALBRÁS/ALUNORTE Industrial Complex, located in the municipality of Barcarena (PA). For this purpose, chemical analyzes of total fluorine were carried out in soils, plants and waters. In the soils, complementary analyzes of Al, Fe, Ca and Mg, determination of pH and mineralogical composition were also carried out. In addition to the data obtained in laboratories, those made available by the ALBRÁS aluminum factory were also used. For the interpretation of the data, geostatistical techniques and visual analysis of isoteor maps were used, which allowed observing the distribution, albeit in a preliminary way, of fluorine levels in soils, groundwater and grasses. It was verified that there is an impact of the industry on the environment, in its area of influence, evidenced by the increase of contents with time and by the “concentric” distribution of the levels of fluoride found.

Desastre socioambiental em Barcarena: a percepção dos moradores de Vila do Conde sobre o naufrágio Haidar
(Universidade Federal do Pará, 2019-05-14) MACÊDO, Jucimeire Rocha; CUNHA, Janice Muriel Fernandes Lima da; http://lattes.cnpq.br/4027012189701116; OLIVEIRA, Euzébio de; http://lattes.cnpq.br/1807260041420782; https://orcid.org/0000-0001-8059-5902
This research has as its thematic delimitation the study about socioenvironmental disasters in the Amazon region, and its main research proposal is to understand the socioenvironmental effects generated by the sinking of the Haidar vessel to the residents of Vila do Conde - coastal community of the Brazilian Amazon. The socio-environmental disaster occurred on October 6, 2015, in which a Lebanese-flagged cargo ship loaded with approximately 5,000 live oxen sank in the Port of Vila do Conde, causing the animals to die through intense suffering, spilling 700 tons of fuel oil in the Pará River, 90 tons of hay bale and 50 tons of rice bales destined to feed the animals during the trip. The general objective that guided the study sought to understand the socio-environmental and health effects of the residents of Vila do Conde, generated by the Haidar wreck. The specific objectives were based on: 1) To characterize the way of life of the residents of Vila do Conde, in a brief historical outline; 2) Analyze the social and environmental effects of the disaster; 3) Investigate the health effects of residents from the Haidar wreck. The path taken to understand the phenomenon has theoretical references based on authors such as: Artaxo (2014), about planetary transformations; Victor Marchezini (2018), who works on the theme of social and environmental disasters, which evoke reflections on the legitimacy of environmental issues and social inequality; Rita Barata (2009) and Ribeiro (2004), who exemplify the understanding of environmental health and also the result of social and environmental inequalities in the field of human health and Nascimento (2010), which elucidates the occurring and recurrent social and environmental disasters in the municipality. from Barcarena. Understanding the complexity of the object of study, the approach used was the quantitative and qualitative research. Regarding the procedures, the field research was chosen. The techniques applied for data collection were semi-structured interviews, application of questionnaires elaborated with mixed questions and records in the field diary. The data collected were organized, categorized and analyzed through content analysis, in a temporal cut, before and after the disaster. The final considerations showed that the socio-environmental disaster led to a series of imbalances regarding health, leisure, the economy and socio-cultural reorganization. Regarding health, 603 medical visits were quantified, and the most recurrent symptoms were: feeling sick, headache, malaise and vomiting. Leisure practices were compromised as the beach was banned. Economic activities concentrated in leisure, tourism and fishing were severely hampered by the beach ban. The departure of residents from their homes, located on the beach of Vila do Conde, thus marks the socio-cultural reorganization after the disaster.

(Universidade Federal do Pará, 2020-10-13) DAMASCENO, José Roberto Pereira; BASTOS, Rodolpho Zahluth; http://lattes.cnpq.br/0697476638482653; LOPES, Luis Otávio do Canto; http://lattes.cnpq.br/1013147545099173
The research aimed to study the port activity and its expansion as a possible generator of socio- environmental conflicts in the communities surrounding the Port Zone of the Municipality of Barcarena, identifying and analyzing these conflicts arising from the installation and operation of the ports to, in the end, propose instruments for conflict mediation. . It is necessary to understand how socio-environmental conflicts occur to motivate sustainability actions and policies that preserve the community against recurring environmental damage in its territory. In addition, it is important to promote transparency in the process and use conflict management tools in the face of complex territorial relations, structuring the agents involved in the search for consensus and equity of rights. Data were obtained through bibliographic and documentary surveys and individualized interviews with residents, port officials, municipal and state authorities. It was concluded that the port activity has great potential for generating conflicts and that the dynamics that involve actions for the operation of the ports of Barcarena cause environmental damage and lasting conflicts between the actors: port companies; community and public power. These conflicts are aggravated by the lack of transparency in Environmental Impact Studies and the absence of the use of self-composition tools for conflict management.

A Implementação da Política Nacional de Resíduos Sólidos e os obstáculos e desafios da inclusão dos catadores: um estudo de caso no município de Barcarena, no Estado do Pará
(Universidade Federal do Pará, 2023-06-16) LIMA, Milene Conde Maués; ELIAS, Leila Márcia Sousa de Lima; http://lattes.cnpq.br/4908432047840911; https://orcid.org/0000-0002-7522-1962
The present study aims to analyze the efforts, challenges, and successful cases related to the inclusion of collectors of reusable and recyclable materials in the municipality of Barcarena, state of Pará, based on the implemented initiatives and their alignment with the guidelines of the National Solid Waste Policy. The research revealed an important Public-Private partnership in the municipality of Barcarena that has been developing actions to organize and train collectors of recyclable materials for their activities; an environmental education program; and investment in infrastructure for a recyclable waste sorting unit. The training and capacity-building program is considered by the collectors as crucial for their professional development and reinforces their role in waste management in the municipality. Environmental education presents itself as another important approach to promote access to information and raise awareness among the local population regarding minimizing environmental impacts through awareness of the importance of selective waste collection and support for collectors, fundamental aspects of proper solid waste management. Overall, the inclusion of collectors in Barcarena has made progress but still faces challenges, and collaboration among various stakeholders proves to be the most viable and essential path to achieve significant results and promote sustainable solid waste management. The good practices identified in Barcarena can serve as a reference for other municipalities interested in promoting the inclusion of collectors and advancing in solid waste management.

A Institucionalização do desenvolvimento sustentável em municípios amazônicos: um estudo de caso de Barcarena (PA)
(Universidade Federal do Pará, 2024-07-12) FERREIRA, Rafael Acatauassú; COSTA, Eduardo José Monteiro da; http://lattes.cnpq.br/4243685710731997
The growth of industrial and port activities in Barcarena (Pará), starting in the 1980s, has generated social and, in recent years, environmental burdens on the municipality. To mitigate the situation, municipal managers have sought, either through executive actions or through institutions aligned with the development agendas of the United Nations (UN), to institutionalize sustainable development. This work analyzes, through exploratory and descriptive research and considering the perspective of the New Institutional Economy (NIE), the results of the institutionalization process of such agendas in Barcarena, especially the 2030 Agenda for Sustainable Development, between the period of 2015 to 2023. To this end, it identified actions and institutions created and promoted by municipal managers; analyzed the municipality's performance in the period using the Sustainability Barometer (BS), a tool from the Amazon Foundation for Studies and Research (FAPESPA), and the Sustainable Cities Development Index - Brazil (IDSC-BR); and, finally, analyzed and compared the results obtained in the indexes. The research result indicated that the process improved indicators related to sustainability in Barcarena, with actions, such as the creation of the Photovoltaic Energy Plant, and institutions, such as the PPA 2022-2025 and the new Tax Code, which can be considered innovative for amazon municipalities. Despite this, the process was still insufficient to solve common issues to Amazonian municipal entities (such as poor income distribution, lack of basic sanitation, quality education, etc.), in addition to others of Barcarena, such as hot spots and pollution and environmental risk management. Managers are recommended to maintain the process, especially improving its social impacts and paying due attention to possible future environmental threats related to climate change; to FAPESPA the recommendations are to provides a more accessible digital platform, in order to improve access to information related to BS; and to the Sustainable Cities Program (PCS), responsible for IDSC-BR, the recommendations are the insertion of retroactive data in the index, referring the period from 2016 to 2021, to increase the relevance of the tool.

Justiça ambiental em território de desastres: uma ação local de resistência em São Sebastião do Burajuba/Barcarena (PA)
(Universidade Federal do Pará, 2020-10-27) CRISTO, Amanda Mesquita; TEISSERENC, Maria José da Silva Aquino; http://lattes.cnpq.br/1799861202638255
The present work aims to analyze actions and organizations of actors mobilized in processes that are configured as struggles against environmental injustice and for the good living in the community of São Sebastião do Burajuba in Barcarena, municipality of the state of Pará, as resistance to issues related to environmental injustices regarding access to and use of water, in a context marked by mining activities. These activities, considered as pollutants to a high degree, result in significant changes in the ecosystem, in the ways of life, in the economic and cultural practices of quilombola communities, indigenous peoples, farmers, extractivists and fishermen. To this end, the concepts of Environmental Justice by Acselred (2010) and Bem Viver de Acosta (2016) were used, understanding that nature and its resources are references linked to a philosophy of life, part of countless histories of struggle and resistance of called traditional populations. Defending against the injustice posed regarding the unequal distribution of risks by industrial activities is presented in the form of complaints and confrontations in Barcarena carried out by the Association of Caboclos, Indígenas e Quilombolas da Amazônia (Cainquiama) and by the quilombola community São Sebastião do Burajuba. It is a research of qualitative methodology, in which in addition to data analysis and basic bibliography, interviews were conducted with several actors from the Burajuba community, including members of Cainquiama. The research also points out that the fight for environmental justice has a long way to go, mainly in a country marked by several social and territorial inequalities. The results indicated that the emissions of industrial pollutants are destined for part of a territory where populations of ethnic-racial origin live whose socioeconomic situation becomes disadvantaged.

Políticas empresariais “sociais” implementadas em comunidades atingidas por projetos minerometalúrgicos no estado do Pará
(Universidade Federal do Pará, 2016-09-18) RODRIGUES, Giselle Viegas Dantas; MATHIS, Adriana de Azevedo; http://lattes.cnpq.br/4097998262711403
This research aims to analyze the “social” corporate policies implemented in communities affected by mining-metallurgical projects. Its main objective is to identify how policies are structured, what communication strategies are used, and what are the socio-environmental impacts caused in affected communities. Critical social theory was used to analyze the data and information obtained, which involved mining companies from the three mesoregions that make up the state of Pará. In the empirical research, representatives of communities, government, corporate companies and private organizations were interviewed using the following methodological tools: on-site observation/interviews, field diary, writing and transcription of interviews, analysis and systematization of interviews, and essay writing. The main results of the research indicate that the "socially responsible" stance affirmed by the corporate companies is based on the need to create consensuses in the communities, to reduce local poverty and to establish the legitimacy of the company over the territory; and also that strategic communication methodologies have influenced the way of thinking and acting of those affected by the mining and the professionals involved, due to the existence of life conditions materialized in everyday life and create illusory concepts to explain the reality of those who suffer the socio-environmental impacts of mining-metallurgical projects. In addittion, it is concluded that despite the economic growth generated by mining and the investment in “social” corporate policies to mitigate socio-environmental impacts in the cities surveyed the communities affected by mining-metallurgical projects continue to suffer from violations of rights and intensification of social, political, economic, cultural, territorial and labor inequalities.

A utilização de uma camada de solo compactado como revestimento impermeabilizante de fundo de bacias de disposição de lama vermelha produzida em Barcarena-PA
(Universidade Federal do Pará, 2010-06-11) BRAGA, Risete Maria Queiroz Leão; BOSCOV, Maria Eugênia Gimenez; http://lattes.cnpq.br/5142308157182335; COSTA, Marcondes Lima da; http://lattes.cnpq.br/1639498384851302; https://orcid.org/0000-0002-0134-0432
International technical specifications and the study of mass transport through porous media for environmental control point out to the need of bottom liners, usually composed of a geomembrane associated to a compacted clay liner (CCL), for waste disposal in soil. In 1995, an industrial unit of Alumina of Brasil S/A started activities in the state of Para, Brazil, to produce alumina, Al2O3, for Albrás Alumínio do Brasil S/A. The wastes of this industry, known as "red mud", are generated by the digestion of bauxite by solutions of sodium hydroxide (Bayer process) and disposed in basins lined by geomembranes. The solid phase of red mud is constituted by hematite, anatase and goethite (residues of bauxite) and sodalite (formed during the industrial process); the liquid phase, initially at pH 12, is rich in soluble sodium. This research investigated the technical feasibility of the utilization of a local soil in the construction of a CCL for the disposal basins, considering its impermeabilization capacity and compatibility with the red mud. The experimental investigation consisted of the physical, chemical and mineralogical characterization and determination of geotechnical (compaction, permeability and collapse) and environmental properties (leaching and diffusion) of the soil. The study showed that the used soil is equivalent to Yellow Latosols of Amazonia: it is silt-sandy, yellow, composed predominantly of quartz, kaolinite and smaller concentrations of goethite/hematite and anatase, and therefore rich in SiO2 and Al2O3 besides Fe2O3 and TiO2. The compacted soil, submitted to seepage of water and solutions of sodium hydroxide at concentrations of 1.23% and 5%, presented permeability coefficient smaller than 10-9 m/s. SEM/EDS analyses of the compacted soil in contact with red mud for over a year identified the diffusion of Na, which content in the soil increased 1950%, however without reaching limit contamination levels. Oedometric collapse tests revealed that the soil compacted in the optimum water content under Proctor standard effort becomes remarkably compressible when saturated with NaOH solutions, which was confirmed by zeta potential, rheometer, and characterization tests with NaOH solutions: solid particles are dispersed and consequently the geo-mechanical behavior of the soil alters by contact with NaOH solutions. The results lead to the conclusion that infiltration of caustic solutions can cause a decrease of the safety factor of dams and CCLs in red mud disposal areas, when geomembranes present defects or holes.
