The Guajará Bay is the main water body that receives sewage from Belém's official network, receiving a daily volume of 18,294 m3/day, which is discharged in natura from the Una channel. This work aims to evaluate the influence of the release of this sewage on the quality of the sediments on the edge of Guajará Bay. For the purpose of comparison, two areas were chosen: one more impacted, located between the Una channel and the district of Icoaraci (Area 1) and another, less affected by the release of sewage, located near the island of Cumbu (Area 2). Sediments were collected at 18 points, 12 in Area 1 and 6 in Area 2. Mineralogical compositions were determined by X-ray diffraction and the concentration of metals in the total sample and in the soluble fraction was studied. The following metals: Cu, Cr, Ni, Pb, Zn, Mn and Fe. Concentrations were determined by atomic absorption spectrometry. The results show that the studied sediments are clayey and constituted mainly by kaolinite, illite and smectite. In Area 1, they present an average of 2.6% by weight of organic matter, with average concentrations of carbon and organic nitrogen of 1.51% and 0.08%, respectively. The concentration of total phosphorus shows an average of 216 mg/kg and as the sampled points move away from the Val de Cans channel, it shows a strong decrease (308 mg/kg to 132 mg/kg). The metals in the total fraction showed the following concentrations: Cu (16 mg/kg), Cr (66 mg/kg), Ni (24 mg/kg), Pb (59 mg/kg), Zn (70 mg/kg) , Mn (531 mg/kg) and Fe (37,181 mg/kg). Regarding the remobilizable fraction, the percentages observed were as follows: Cu (50%), Cr (15%), Ni (17%), Pb (51%), Zn (71%), Mn (83%), and Fe (47%). In Area 2, the average concentration of organic carbon was 0.43% by weight and that of organic nitrogen was 0.1% by weight. Organic matter reached a value of 0.74% by weight and organic phosphorus 495 mg/kg. Regarding metals, the average concentration observed was: Cu (13 mg/kg), Cr (36 mg/kg), Ni (35 mg/kg), Pb (55 mg/kg), Zn (33 mg/kg), Mn (214 mg/kg) and Fe (17,029 mg/kg). In the rewoundable fraction, the metals presented the following percentage in relation to the total content: Cu (41%), Cr (12%), Ni (32%), Pb (32%), Zn (73%), Mn (67 %) and Fe (70%). The concentrations of metals found in Area 2 were lower than those observed in Area 1, with the exception of phosphorus. The results confirm the strong anthropogenic influence on the quality of sediments in the Guajará estuary.

A cidade entre memórias e fotografias: uma prática de ensino patrimonial nas aulas de História - Icoaraci – Pa
(Universidade Federal do Pará, 2020-08-28) PEIXOTO, Williomar de Souza; MACÊDO, Sidiana da Consolação Ferreira de; http://lattes.cnpq.br/4202561791565993; https://orcid.org/0000-0002-1481-9274
This dissertation has as main theme the dialogue between Heritage Education and local History in the teaching of History in order to contribute to scientific research on the didactics of History. It seeks paths that can lead students to historical knowledge, in fact, meaningful. To this end, it aimed to demonstrate the importance of the treatment of history teaching with themes of local history, and heritage, considering the important connection that they have with the perspective of the development of the students' identities and sense of belonging, suggesting to present a didactic sequence within these research fields mentioned above. In this sense, mainly oral sources were used, derived from the survey of memories of part of the residents of the district of Icoaraci, and consecutively the recording of photographic images of the spaces and practices listed in these reports of memory. Such practice aimed to place the student as the protagonist of the research, enabling them to apprehend a past from their place that for them was previously silenced, helping them to gain notions of a time full of ruptures and permanences in the present. The production is a means of expanding the debate on heritage teaching, and of research in teaching history from the uses of different memory spaces as a source of analysis. The work suggests the existing debate about the definitions and uses of cultural heritage, their purposes and what projects of society they serve. The material result of this project is configured in a product in a booklet format, systematizing the didactic proposal in heritage teaching carried out here, having as main target teachers of the basic education network, as well as the collection of images produced by the students, in addition to the bank itself of data that organizes the notes on places, customs, local practices from the memory of the elders and students.

Ensino de história e a temática da alimentação: possibilidades acerca da identidade, memória e pertencimento. Icoaraci/PA
(Instituto Histórico e Geográfico do Pará, 2020-05) PEIXOTO, Williomar de Souza
Food as a cultural element helps to demarcate multiple traits of different identities in societies over time and in different historical contexts. Through the habit of eating, which is one of the human needs, we can use historical analysis as this habit turns into pleasure rituals and social conventions, which characterize cultural peculiarities, divide classes, at the same time that it allows different forms approaches on aspects of historical culture. The history of food today has its proven importance in the writing of history. Thus, the field of research on the teaching of History has been gaining new contributions from the history of food. This theme allows the teaching of History to deal with the evolution of habits, eating habits, in addition to themes dear to historical knowledge, such as; work, environment, social and economic problems, or political aspects. This article seeks to present some perspectives and possibilities on Food and History Teaching experienced during research within the scope of the Master's project of ProfHistória / UFPA. The research was based on the field of heritage teaching in Icoaraci (district of Belém) with a local elementary school class, proposing a didactic sequence that analyzes the historical cultural heritage of Icoaraci, through workshops, dealing with old iconographic sources, interviews with elders, and visiting places of memory. During this research, students and people interviewed pointed out various practices and customs related to food as identity traits, which led us to address this issue.

Virtualização da paisagem de bacias hidrográficas da zona de expansão urbana do município de Belém-PA por meio de cartografias temáticas digitais
(Universidade Federal do Pará, 2005-07-04) OLIVEIRA, Ricardo Alexandre Fialho de; BORGES, Maurício da Silva; http://lattes.cnpq.br/1580207189205228
The municipality of Belém (PA), located in the northeast region of the State of Pará, is characterized by having a geographical position close to the Atlantic Ocean, flat relief, low altitudes and typical climate of the Amazon (hot and rainy) where high rainfall prevails. (2,600 to 3,300 mm/year), conditioning the formation of the landscape. And this landscape is carved in rocks of the Barreiras formation and in Post-Barreiras sediments, being conditioned to neotectonic transcurrent processes, evidenced by two large groups of faults on the macroscopic scale, which cut the Tertiary and Quaternary sediments. One beam is presented with direction N05E and N60E, the other beam with direction N45-55W. These faults produce “micro-reliefs”, topics of Amazonian cities, which are often imperceptible, are important when interacting with hydrological, neotectonic and territorial occupation and space management processes. The association and/or interaction of these factors, or some of them, are the main responsible for several problems observed in Belém, regarding the use and occupation of the physical environment in the Urban Expansion Zones (ZEU) of the municipality of Belém. In this work, the landscape structure and its spatial pattern are virtualized in the Paracuri, Curuperé and Tamanduá river basins, located in urban expansion areas of the municipality of Belém, through digital thematic cartographies derived from Numerical Land Models (MNT). ). The generation of such cartographies made it possible to extract information associated with physiographic aspects and processes (natural and artificial) responsible for surface modeling in hydrographic basins. Because the three-dimensional representation of space, using geoprocessing techniques, acquires fundamental importance, when associated with applications aimed at the use and occupation of the physical environment in urban spaces of large cities, constituting valuable information for future works involving environmental aspects. , geotechnical and planning of use and occupation of the physical environment in hydrographic basins. And the integrated use of MNT's with other types of data, expanded the knowledge about the reality of the landscape, allowing to visualize the phenomena resulting from natural and anthropic interventions on the urban space, and to submit such models to evaluation.
