RESUMO:

The effect of population growth creates social, economic and ecological problems, with reflexes that can be perceived when assessing changes in land use, as this phenomenon is amplified annually, altering the landscape to meet human needs. Among these changes, it can be seen, road infrastructure, construction of housing, shops, schools, which favors the waterproofing of the soil, consequently changing the local hydrological cycle and the microclimate, in addition to the functions and services of the ecosystem. This process reduces the vegetation on the banks and affects water bodies and the entire aquatic ecosystem. In this sense, the general objective of this work is to evaluate the influence of land use change due to urbanization on water quality in urban water bodies in Brazil. To answer this objective, the dissertation was divided into two chapters, which are in the format of articles. Chapter 1: It conducted a survey on the main studies that address urbanization and water quality in Brazil. For this chapter, a systematic review was chosen, following the PRISMA-P protocol. A search for scientific articles (published in the last decade and directly linked to the topic) was conducted in the main databases, and subsequently analyzed systematically through 27 predetermined recommendations, presenting a portrait of the research and methodologies used in Brazil. Of the articles included 83.3% (15) was published in the last five years, of which 22.2% (4) had a high-quality evidence, 50% (9) were classified as moderate quality of evidence, and 17.8% (5) presented low-quality. It is suggested that studies related to the negative impacts of the urbanization process on the quality of water bodies be expanded, so that emergency measures can be proposed, avoiding the scarcity of freshwater sources. Chapter 2: To assess the influence of land use and occupation on water quality, a water body was selected in the urban area of the municipality of Santarém, Pará. Water samples were collected from the water body, in six locations, starting in the spring. The collection was conducted bimonthly and will count four campaigns during the last term of 2019 and the first term of 2020, making it possible to assess the seasonal changes in the water body. Physical, chemical and bacteriological parameters were evaluated. To evaluate the results of the water samples, the Water Quality Index (IQA) was calculated, which uses nine parameters. Points 1 and 2 have higher IQA values, as they are found in areas with a greater degree of preservation of the riparian forest, point 3 is in an area with a greater agglomeration of people, as it is used for bathing people, during leisure or animal bathing, which can be observed with the lowest IQA values. The alteration of the soil in urban areas is constant and tends to grow following the population growth of the city, a factor observed during this research. During the study, it can be seen that the water in the stream had changes in parameters between each campaign and at each sampling point, proving the difficulty in interpreting the environmental characteristics of an aquatic environment, this is due to the quality of the water, usually having reference direct use and occupation of the surrounding soil or with the existing uses nearby. Note that the Irurá stream is a water body that must be preserved as determined by the Brazilian Forest Code.
