Alterações histopatológicas dos rins de macacos prego, Cebusapella (Linnaeus 1758) após exposição crônica a baixas doses de metilmercúrio
(Universidade Federal do Pará, 2014-02-28) SOUSA, Andréa do Socorro Campos de Araújo; SILVEIRA, Luiz Carlos de Lima; http://lattes.cnpq.br/9383834641490219
Mercury has been a major environmental and occupational risk and it still remains a problem for human health in the Amazon region. Although studies have shown that mercury affects various tissues and organs, kidneys are the target organs to the metal toxicity. Thus, the aim of this study was to investigate the effects of chronic exposure to low doses of methylmercury on renal parenchyma of Cebusapella, adult males exposed during 120 consecutive days with daily oral doses of 1.5 μg in the diet. The concentrations of total mercury in the animals’ blood were monitored every 30 days using a cold vapor atomic spectrophotometer (201 Hg), compared to the control group. The method used for histopathological analysis was the immersion in paraffin for staining with hematoxylin and Eosin, Masson's CAB and PAS. The immunohistochemical investigations included reactions for detection of smooth muscle actin ( IA4 ), muscle actin ( HHF35 ) and cytokeratin (AE1 and AE2). The results showed that treatment with mercury caused significant differences (P < 0.001) between the exposed and control groups. As for total Hg levels, histopathologicalchanges just likehydrops in Proximal tubuleswere observed, a common finding in methylmercury exposure in other species, with no significant changes in creatinine and urea concentrations. The Person correlation test showed a strong negative relationship between mercury concentration and animal body weight loss (P < 0.0001). Another important finding was the decrease in mesangial cells number, which suggests that methylmercury executed its nephrotoxicity, affecting not only the renal tubular system, as well as the glomerular mesangium cells, making necessary a greater amount of experimental studies to clarify which mercury concentration alert level is capable of triggering aggression mechanisms and kidney injury in subjects exposed to methylmercury.

(Universidade Federal do Pará, 2010-04-23) SILVA JUNIOR, Orleno Marques da; SZLAFSZTEIN, Cláudio Fabian; http://lattes.cnpq.br/1348005678649555
The city of Alenquer, located in the Lower Amazon region of Pará State, historically suffer the threat of flooding. Every year in the flood season, the Surubiú stream increases your level, flooding the lower parts of the city. This thesis analyzes the existing flood risk in the city of Alenquer providing tools for management and improvement of the actions of government. The threat analysis was based on a methodology that combines historical data, hydrology, map building and participatory field work with GPS, identified three distinct areas in the city: (i) high susceptibility area annually affected by floods, is 8,4% of the city area (ii) area of moderate susceptibility, only achieved when the highest rates observed streamflow and (iii) the area that even larger floods is not achieved. The calculation of vulnerability occurred from the construction of an index that includes census data from demographic field work to identify the essential elements and units of responses. After the application of the index found that the 17 sectors of the city, five have high vulnerability, and the other moderate vulnerability. In the risk analysis data vulnerability and threats were integrated and again three areas in the city were identified (i) the high risk area represents 9.45% of the city, where there is high concentration of essential elements and several responses, leading to social and economic damage upon the occurrence of flood (ii) area of moderate risk, 30 % of the city and (iii) low risk zone which corresponds to 60.55% of the city. The Master Plan of the municipality was analyzed with a few questions to verify the inclusion of the theme of threat, vulnerability and risk in this document, after the analysis can conclude the lack of discussion of this theme in the master plan. The results of the research are important for supporting public policies and documents required by the Civil Defense at the time of disasters.

Assessment of surface water in two Amazonian rivers impacted by industrial wastewater, Barcarena City, Pará State (Brazil)
(2011-08) LIMA, Marcelo de Oliveira; SANTOS, Elisabeth Conceição de Oliveira; JESUS, Iracina Maura de; MEDEIROS, Adaelson Campelo; FAIAL, Kelson do Carmo Freitas; ALVES, Claudio Nahum
In 2007, surface waters were collected from 21 sampling points in Barcarena City in Northern Region of Brazil: one sampling point located in a stream that receives discharge of wastewater from a kaolin processing industry and flows into the Curuperê River, three sampling points located near sources that emerge on the left bank and flow into the Curuperê River, nine sampling points in Curuperê River, which flows into the Dendê River, and eight in Dendê River, a tributary on the right bank of the Pará River. For all water samples were quantified 14 physicochemical variables and levels of 12 metals. The results in the points near the sources of the Curuperê River presented physicochemical profile and metal levels which are typical of surface waters being used as reference to compare and identify possible changes in the chemical characteristics of the other sampling points. The comparison between the results obtained for the sources of the Curuperê River and the ones for the point near the discharge of industrial wastewater revealed strong changes in the values of 6 physicochemical variables (pH, electrical conductivity (EC), total dissolved solids (TDS), sulfate (SO4), ammoniacal nitrogen (NH4-N) and salinity) and an increase in magnitude of the levels of four metals (Al, Fe, Mn and Zn). These facts characterized that the wastewaters were discharged into the environment without adequate treatment. Results in other sampling sites showed that these anomalous conditions were also found along the Curuperê and Dendê Rivers, especially during low tide. This chemical characterization of the waters allowed to identify harmful conditions to aquatic ecosystems and potential health risk for the local people, who use the rivers for drinking water, recreation and transportation.

Cidade de Belém e natureza: uma relação problemática?
(Núcleo de Altos Estudos Amazônicos, 2010-07) LOUREIRO, Violeta Refkalefsky; BARBOSA, Estêvão José da Silva
In an unstoppable and rapid manner, Belém is losing it’s urban green. This loss presents itself with unique characteristics when compared to other Brazilian cities, that equally suffer from the urban speculation and the chaotic occupancy of the land. The mango trees – witch are listed as part of the State’s patrimony as common goods and must be permanently preserved – are actually the most endangered species, no longer characterizing Belém as the mango tree’s city. Besides, differently from the other capitals, where the private sector has been the most res ponsible for the environment damage, in Belém, actions and omissions of the government to the city are more important to the deterioration of the urban landscape, it’s green areas and waters than the private sector.

(Universidade Federal do Pará, 2023-06-30) PIRES JÚNIOR, José Alberto; LOPES, Luís Otávio do Canto; http://lattes.cnpq.br/1013147545099173; https://orcid.org/0000-0002-6209-9646; FLORES, Maria do Socorro Almeida; http://lattes.cnpq.br/8875436559577793; https://orcid.org/0000-0001-9154-6938
One of the major concerns observed today is the generation, allocation and inadequate disposal of waste and waste. The present work aims to identify how Vila de Algodoal produces, collects and disposes of waste, waste and waste produced. With the research having a legal-environmental profile, all proposals that seek solutions and/or mitigation of identified environmental impacts will be guided by Law No. 12,305/10, among other relevant legal provisions. The general objective of the present study comprises determining the competence for managing solid waste, mainly organic waste of animal origin, and how this collection has been occurring in Vila de Algodoal, with the aim of not only identifying appropriate disposal strategies, but also highlighting the possibility of obtaining production inputs from these materials. To this end, analogous research involving themes related to waste management was used as a reference, as well as photographic records, participation in solid waste collection actions and also a search for information with local actors in order to become aware of the current way of collection and disposal of solid waste in Vila de Algodoal and whether the practice adopted finds legal support. Finally, a video was created portraying the current scenario of waste disposal in Vila de Algodoal, including possible solutions to the problem and also a Technical Note to be forwarded for evaluation by the Management Council of APA Algodoal Maiandeua, Ideflor- Bio and Chamber of Councilors of the Municipality of Maracanã-PA, which identified the current profile of production, allocation and destination of waste and rejects in the locality and contains alternatives for mitigating the observed environmental impact, focusing on the viability alternatives for transforming an eventual threat into opportunity.

Estratégias prevencionistas à doenças causadas em locais de riscos em período chuvoso em Limoeiro do Ajuru – Pará.
(Universidade Federal do Pará, 2019-01-15) OLIVEIRA, Jackline Leite de; SILVA, Maria de Fátima Vilhena da; http://lattes.cnpq.br/0996110060293347
The natural disasters can cause public calamity on the grounds of the flooding areas associated with rainfall indexes, which cause diseases and health problems in a certain population in the city of Limoeiro do Ajuru. The objective of this research is to contribute to the risk management and minimization of diseases prevailing during the rainy season in the city of Limoeiro do Ajuru. The research used the methodology of quantitative and qualitative analysis, rainfall data from 2007 to 2017 of the station Joana Coeli, on the website of the Agência Nacional de Águas (National Water Agency), clinical data of the Municipal Hospital of Limoeiro do Ajuru, data from the Sistema Estadual de Saúde Pública (State Public Health System), in addition to the semistructured interviews that helped to outline the social, economic and acculturation profile of the target public, these data were tabulated in a spreadsheet. The results obtained in the ten years, 2007 to 2017, revealed the pluviometric behavior associated to the prevalence diseases indexes: acute diarrhea and acute respiratory infections, which correlate the research areas with flood spots in the streets: Nova 4, Juscelino Kubitschek, and Umarizal, these being selected by the addresses of the demands affected with the diseases that were attended in the Urgency and Emergency of the city. The research had the following conclusions: It was found a correlation between rainfall indices between acute diarrheal diseases and acute respiratory infections, and floods and the sociodemographic profile of the target population, revealing the need for education and health investments, as well as sanitation in the areas. To partially comprehend this issue, the need to create a booklet that points out preventive measures and that can minimize prevailing diseases emerged in this research. The release of the booklet will be the responsibility of the Conselho Municipal de Saúde (Municipal Health Council) to other social sectors and populations subject to the problem of flooding in the city Limoeiro do Ajuru.

A gestão dos riscos naturais à erosão e inundação nos planos diretores de municípios da zona costeira (estado do Pará)
(Universidade Federal do Pará, 2011-10-10) ESPÍRITO SANTO, Celina Marques do; SZLAFSZTEIN, Claudio Fabian; http://lattes.cnpq.br/1348005678649555
The Para’s Coastal Zone is characterized by the complexity of their physical and social support. Its location marks the existence of natural hazards - erosion and flooding, which combined with a lack of consistent public policies makes people vulnerable and compromises their life quality. However, if the problem of natural hazards are recognized and considered by municipal administrators, mainly on issues of land use, damage and loss of life and material can be avoided. Thus, those who depend on these areas for survival can have a sustainable way of life, without been exposed to unsanitary conditions. It is considered that the instrument responsible for the urban planning of the territorial organization at a municipal level is the Municipal Master Plan. This is legal according to the Article 182o of the Federal Constitution considers it as regards the basic tool to guide development policies in cities. Considering the functions of the Municipal Master Plan and the reality of the Coastal Zone the present study is concerned with this problem, because potential natural disasters are putting human lives at stake. Thus, the main objective of this study is to analyze how the Municipal Master Plan for coastal municipalities of Pará incorporates the theme of natural hazards of erosion and flooding, and how this is reflected in public policies associated with risk management. Specific objectives include the following: I - Identify and describe the natural hazards of erosion and flooding of coastal cities in the State of Pará, and II - Review the management of natural erosion and flooding in the sectors policies of territorial organization in the Municipal Master Plan for coastal municipalities of the State of Pará. To pursue our goals, this study was developed at the towns of Belém, Bragança and Salinópolis under the following methodology: the search of the theoretical and conceptual references; the research and review of basic municipal information (MUNIC) and the Civil Defense organ reports of disasters as well, and also the appliance of an array to analyse the risks present at the municipal master plans. Although the natural hazards are largely found at this field of study, we could find very little information at the MUNIC data source related to problems such as erosion and flooding phenomenas. Through the Civil Defense organ data base, between the years of 2007 and 2010, only four towns, all of them on the shore area, had reported disasters, which only the town of Bragança was taken in consideration on this present essay. On our reviews of the cities government master plans, we found statements in total opposition of what they were supposed to be, probably as a result of a very trivial aproach of these matters on previous studies. In our pont of view, the government Master Plan is an important diagnostic tool on illustrating the city’s diagnosis on these situations, as well it should establish the guidelines supporting the land use. Knowing the risks, by identifying the hazardous conditions in areas subject to erosion and flooding, is the only way to make possible to support the government action, which have been claiming to intervene in the Coastal Zone seeking the improvement of the environmental and social conditions lived by those who inhabit the place.

This master thesis comes from a concern about the lack of recognition of social and racial inequalities as structuring elements in the production of urban space in Brazil, mainly by environmental studies. Address the exploitation of the environment to achieve profit and favor certain social classes that have control of land ownership, and social and political power, it has been the most common approach in the Brazilian context. In the context of an Amazonian city like Belém, flat relief and water stand out as historically dynamic elements of urban occupation and disproportionately more severe environmental consequences for certain social groups. Thus, this master thesis aims to reveal environmental injustices and social and racial inequalities in the production of the urban space of Belém, historically marked by rentier urban growth, by territorial dispute and countless environmental consequences. The methodological procedure was diverse, first of all it started with a bibliographic review about nature, Brazilian racial issue, and the sociospatial formation of Belem. Then, it was made analysis of urban growth patterns of the metropolitan region of Belem, through digital rating techniques of orbital images, with two periods of time (1984 to 1999 and 1999 to 2018). The same period of time selected were used to analyze the urban occupation and the hydrological impacts in the river basin of the Metropolitan Region of Belem. To conclude, it was made analysis of socioeconomic, racial, environmental and urban infrastructure data of Belem. The obtained results show that there is a correlation between the urban spot, the vegetal cover and the reduction of adequate rates for the operation of river basins in the Metropolitan Region of Belem. Furthermore, it was verified that two out of three people live in the flooding area of Belem, which is mostly composed of black and low-income people. It was also verified that the overflow in the city match with the flooding susceptible areas, due to the lack of urban drainage and the incapacity of public management of the territory, masked with a speech which blames the nature. It is conclude that the environmental issues in the urban space of Belem affect unequally the population of the city and they are based on structures of political, economic and social power grounded in racism and inequality.

This thesis analyses the Risks Monetization in the Work Environment – phenomenon that authorizes the financial compensation for the worker due to his exposure to risks existing in the place of work –, which is done by the optics of the Egalitarian Liberalism of John Rawls and Ronald Dworkin. The first chapter analyses and compares the liberal egalitarian theories presented by John Rawls and Ronald Dworkin with the Economic Analysis of the Law theory of Richard Posner. The second chapter demonstrates which are the brazilian juridical practices related to the risks monetization. The third chapter makes a norm and principles based analysis in order to answer if it is necessary to reform those practices, analyzing, yet, which are the obstacles for the effective workers protection.

The region of the Calha Norte, located in the lower Amazon region of Pará State, historically suffer with several types of threats such as floods, Floods, Flooding, Erosion, Drought, flood, heavy rains and droughts, all recorded by the civil defense. Every year, either during the rainy season or dry season, the population is vulnerable to such events. The present work is to adapt a methodology that allows the incorporation of the theme management of natural hazards in Ecological and Economic Zoning of Brazil, taking as a case study of the ZEE of the Calha Norte do Pará providing tools for the management and improvement of public power actions. The analysis of the threat was based on a methodology that combines historical data, geomorphological map, geologic map, topographic map, slope map, identified the three kinds of analyzes: (i) area of high susceptibility (ii) area of moderately susceptible and (iii) area of low susceptibility, thus generated maps of the threats of flooding, geomorphological and droughts. The construction of social vulnerability was based on the construction of the Social Vulnerability Index (SVI) and the Index of Response Units (IUR), both from the 2010 census and the National Register of address for Statistics (CNEFE) both IBGE. After application of the index it was found that the total of 397 census tracts in the study area, 365 sectors are highly vulnerable, and other moderate and low vulnerability, which portrays as a concern with the area. In the risk analysis data vulnerability and threats were integrated and re-classified into three levels: (i) High risk, where there are few concentrations of units and high-threat responses, which may cause social and economic damage occurs when (ii) Middle Level, the result generated by crossing areas of high x low and (iii) Low risk, which resulted in two cartographic products: Risk Map and the Flood Risk Map Geomorphological. The Ecological and Economic Zoning of the Calha Norte of Pará was analyzed with a few questions to verify the inclusion of the theme of threat, vulnerability and risk in the document, after the analysis can be conclude the lack of inclusion of the theme in technical document. The results obtained in this research are important for supporting the creation of regional planning and public policy for the region.

Risco ambiental, incerteza Keynesiana, economia ecológica: rumo a uma abordagem macroeconômica ecológica

This study aims to investigate the relationship between environmental risk and the fundamental uncertainty that acts on the agent at the time of decision-making in order to generate a new theoretical approach on the relationship between the variables. As a secondary objective, we sought to extend the post-Keynesian literature to the point where it relates to ecological macroeconomics. To achieve the proposed objective, the dissertation is divided into two chapters, the first chapter discusses the convergences and divergences between post-Keynesian theory and ecological macroeconomics and the second chapter explores the relationships between environmental risk, fundamental uncertainty during the process of decision making. The first chapter adopts a context of climate change where there is growing concern about environmental sustainability and financial stability. Thus, the characteristics of post-Keynesian theory and ecological economics are often associated, as it is considered that together they can contribute to solutions to economic, social and environmental problems. The first chapter performs a theoretical approximation between post-Keynesian theory and ecological macroeconomics, identifying their main convergences and divergences. From a bibliographic survey, it appears that the currents of thought have significant similarities and an approximation between the two is possible and can be beneficial for both. The second chapter points out that there is a need to fill the knowledge gap between the uncertainty of the occurrence of climate phenomena and the risk of these phenomena occurring and aims to understand the relationship between fundamental uncertainty and environmental risk in the context of the economic system and how this can affect the decision-making process. Based on a bibliographic survey, it appears that fundamental uncertainty is an intrinsic characteristic of environmental risk and negatively interferes with decision-making. There is a multiplication of the set of uncertainties associated with the absence or insufficiency of knowledge during the decision-making process, which adds to the uncertainty intrinsic to environmental risk. The final result is expected to contribute to the development of a post-Keynesian macroeconomics that takes environmental aspects into account. In this way, the present work contributes to the extension of the post-Keynesian literature in the point where it relates it to ecological macroeconomics, in addition to generating a new theoretical approach on the relationship between environmental risk, fundamental uncertainty throughout the decision-making process of decision.

The present work was accomplished at Conde’s Village, municipal district of Barcarena in Pará State, with objective of studying the technological hazards related to the oil leak, aiming the real menace situations and the vulnerability of the local population. The methodology based on three stages: bibliographical rising on the concept of technological risk; field work for the Identification and characterization of the menace areas in the port zone and of the area of vulnerability in Conde's Village through technical visits, interviews, application of questionnaires, observations and photographic registrations; and finally cartographic rising and use of satellite images IKONOS for delimitation of the menace areas in the port, setorization of Conde's Village and for the making of thematic maps. In the port zone of Conde's Village we identified as main menace areas to the leak: moorings area, where the leant against practice, load, discharge and provisioning of ships and rafts with combustible oil are constant, presenting menace level that is going of a lot the extremely probable of happening; Access area, defined by the bridge through where it travels the pipeline, presenting menace level as probable of happening leak and the stock area, where it concentrates the storage tanks and platforms of provisioning presenting menace level that is going of the probable to very probable of happening leak. In Conde's Village the social vulnerability pointed that the population of the section river, in most fishermen, it presents larger vulnerability degree, proceeded by the inhabitants of the section beach, as owners of huts, that present medium vulnerability degree, and with low vulnerability degree they are the inhabitants of the section firm earth. Therefore, a casualty with oil will cart a reaction that it is angered to diffuse at the whole Villa, interrupting the main change flows between the groups and its respective activities.

In the Amazon, specially in the state of Pará, the use of pesticides has been set as a regular practice in the last 20 years and was intensified in the last decade, through the re-configuration of agriculture in the county, with maximization of permanent cultures and technological changes inserted in the agricultural practices and into the labor relationships, being its predominant use, as for the Igarapé-Açu county, the mild and high risk of intoxication, including forbidden substances in the other countries which, under the label of “technology transfer”, have been used without the evaluation of its impact over public health, the environment and the food chain into which the human being takes part. It is understood that this is a public health question in interface with the referred ones in occupational health and environmental health. The research which has guided such paper was developed in the Cumaru branch in Igarapé- Açu county in the state of Pará, with 20 peasants in a situation of long exposure to pesticides. It had as a main aim to trace the morbidity profile of the focused group, more specifically the arise of symptoms of anxiety and/or depression in the situation of chronic intoxication, as well as to recognize their perceptions of the risks to what they are submitted from the usage of such substances in their labor. It was out of the point that the theoretical-conception of work, health and environment joint, understanding health as going beyond the absence of illness or continuous well-being, entering in a single way into each individual’s life who shares with the community events that cause diseases, but that express in a single way through co-factor which insert into each one’s biography, making it worse or minimizing the effects of shared risks. Labor, understood as structuring element of identity and subjective of the individual, plenty of meanings, culturally transformed, being a way of living and dying. Field research was performed in two steps, being the first one to recognize the spaces and ever day practices of the group, considering age and gender, through participative observation and informal chats with peasants and their families in domestic and labor rooms. The second step was performed through psychological evaluation interviews with peasants. It was evidenced the chronic intoxication situation and the incidence of a group of symptoms, among which there are some ones linked to anxiety or depression expressions, being these ones named as “nervous” by the peasants. Those ones already know parts of the risks over their health and environment, but they think of it relatively, not relating the usage of pesticides to the presented symptoms and minimizing them, as well as the risks, anchoring to social representatives that support them on their beliefs about labor and health in defensive strategies shared with their partners.

This dissertation presents the complexity and importance of the phenomenon of fallen lands for the inhabitants on the banks of the Amazonian rivers. The occurrence of this river bank erosion causes damage and concerns in several regions of the Amazon. The diversity of triggering factors reflects the complexity of the topic. This research aims to evaluate the use of the term "fallen lands" in the context of the Amazonian rivers, defining the affected áreas. The objectives are achieved from a systematic review, using environmental data from the Geological Survey of Brazil (CPRM) and National Water Agency (ANA), socioeconomic data from the 2010 Census (IBGE) and the adaptation of the Emergency Action products for the Delimitation of Areas at High and Very High Risk to Floods and Mass Movements - Risk Segmentation (CPRM). It resulted in the analysis of previous research, grouped by period, type of publication and applied methodology, characterization of affected areas described in the literature with regard to geology, geomorphology and water security. The profile of the impacted population points to the vulnerability of communities and reliance on effective government measures to improve the quality of life and responsiveness to the risk of environmental disasters.
