Avaliação da emissão de material particulado e dióxido de nitrogênio na usinagem de misturas asfálticas

Abstract

The present study evaluated the atmospheric emissions from the process of manufacturing asphalt mixtures. Asphalt paving services are of great importance for the development of cities, especially in urban centers where there is a greater need to dispose of goods and people. However, the transport infrastructure industry can generate environmental problems, in particular, significant contributions to air pollution, since several pollutants are emitted during asphalt paving services. In order to analyze the impact of the manufacturing of an asphalt mix, passive sampling method was used for NO2 analysis, and active sampling for particulate matter (PM) analysis. The results showed that PM concentrations in the plant exceeded the limit values established by WHO and CONAMA, for air quality standards, while NO2 concentrations were below these limits.
