Abstract: Anthropic sources of air pollution are important emitters of different pollutants, including particulate matter. The northeast of the Pará Amazon goes through an intense process of growth due to the different uses and occupation of the soil, constituting as potential sources of air pollution. Given the complexity and heterogeneity of the organization c to that of space, it is difficult to identify and quantify accurately to all these sources, however, the vehicle emissions, activities in factories and industries, construction, burning of fossil fuel and burning of biomass are considered as the main anthropic sources of particulate matter. On the other hand, the State of Pará still does not have systematized information on these sources of pollution, added to the fact that the State will host in 2025 COP 30 in the City of Belém, with significant structural changes in land use and occupation that can release large amounts of particulates and other pollutants into the atmosphere. Thus, this work aims to identify and quantify the stationary and stationary sources of particulate matter in 05 Municipalities: an urbanized area in Belém-Pa; a coastal area of mangrove located in Bragança-ESPa, an area near the sea located in Salinópolis-Pa and a pasture area, affected by mining, in Barcarena-Pa. The municipalities were chosen due to the different uses and occupation of the soil and potential emission of particulate matter. For this, this study has been carried out following the following steps: (1) academic and documentary survey, this and, searches on government websites, research platforms for (inter)national studies, through papers published in the area; (2) by geolocaliza c ao and mapping of sources, taking into account the local economic activities, including the energy and vehicle matrices (different types of fleet and supply stations); and (3) visits and observes c oes in loco, in the study municipalities. Industrial, agricultural and commercial areas will also be considered. The result is a database; an Invent Ario in edito de fontes de emiss oes na por c ao nordeste do Estado do Para . The results subsidize the informs t t ecnicas essential for the future Invent Ario of atmospheric emissions in the State. So far, identified as the main sources an industrial park for the washing and refining of aluminum, a large cement factory, dozens of enterprises that use firewood as a source of energy for the production of flour and artifacts, added to the vehicular sources, construction and the intentional or unintentional burning.
