The atmospheric air pollution started to become a public health issue in the Industrial Revolution, when the current urbanization system was defined. Chemical species emitted via anthropological activities are capable of acting on people, animals and plants, making air pollution one of the greatest problems in urban areas today. In this sense, the present study aimed to quantify the emissions of CO, CH4, NO, NO2 and SO2 in urban area of the municipality of Lages/SC, comparing their concentrations with control points located in an Environmental Protection Unit. It was verified if the concentrations of CO, NO2 and SO2 are in accordance with the air quality standards, as well as their respective levels (attention, alert or emergency level), as established by the CONAMA Resolution n. 491/2018. The air quality rate was compared with values determined by the CETESB air quality index. All samples were collected and analyzed (at four replicates) using portable measuring instruments. The meteorological influences on the studied pollutants were evaluated in both control and urban areas. The NO2 levels in the study atmospheric air exceeded the values of the quality standard, being considered as very bad air. Overall, there are potential risks for people breathing this type of atmospheric air.
