SUMMARY:

Fugitive emissions are a problem of air pollution that reach local and global levels, given that landfills are an important source of anthropogenic emissions of Greenhouse Gases (GHG). Influenced by several factors, fugitive emissions are related to the waste and the cover layer, such as the depth and quantity of gas drains, the dimensions of the cell where the waste is disposed, the age of the waste, the weather conditions of the region, the presence of cracks in the layer, the soil properties and the thickness of the liner. GHGs are colorless and odorless gases that act as asphyxiants, and their exposure causes several harms to the population's health, in addition to irreversible damage to the environment. In this context, understanding the gas flows through the cover layer and the factors that interfere in this process, during the landfill operation phase, can provide important contributions to the mitigation of environmental impacts, intensifying the systematic monitoring of concentrations of air pollutants . Thus, this study aims to perform an assessment of fugitive GHG emissions from the Waste Treatment Center in the city of Maceió – AL, as well as to model the dispersion of gases produced in the landfill, evaluating the results of the generated impacts. The AERMOD View software, an atmospheric dispersion model very common in several surveys, will be used to predict concentrations at selected locations of downwind receivers, in order to estimate compliance with national air quality standards, in accordance with current regulations. At the end, a Leopold Matrix will be developed as an environmental impact assessment tool, adapted to assess fugitive emissions from the vicinity of the landfill, in order to verify how these gases affect the air quality of the population living in adjacent neighborhoods. It is expected that with this work, propose models for estimating atmospheric fugitive emissions in the landfill area. These models can present an exponential form and estimate the fugitive emissions of gases considering the presence of cracked and uncracked regions in the landfill cells.
