Abstract
In Campos dos Goytacazes is a city located in the Northern region of Rio de Janeiro State, Brazil, the main source of air pollution are exhaust from vehicle engines powered by diesel oil, such as buses and trucks. It is known that the combustion of diesel oil is source of many contaminant gases such as: nitrogen oxides, SO 2 , CO and hydrocarbons. At this work, we use a CO 2 laser photoacoustic spectrometer to analyze gas samples collected in a bus characterized by an intense traffic. After this study, some gas species of environmental interest, such as SO 2 and NO 2 , were detected and identified in the collected samples, at level ofppm.
