Abstract: Manaus, a city of more than two million people, suffers problems arising from strong sunlight and aggravated by several factors, such as traffic congestion and greenhouse gas emissions generated by evaporation and burning of fuel. The present study examined Carbon Monoxide (CO) and Nitrogen Dioxide (NO 2 ) emissions in an urban area of the city using different methodologies. CO and NO 2 were measured using automated and passive analyzers, respectively. Meanwhile, direct monitoring of these pollutants was performed in vehicular sources in the vicinity of sampling locations. Results showed that levels of carbon monoxide vary over time, being higher during peak movement of vehicles. NO 2 values have exceeded the recommendations of the World Health Organization (WHO), and monitoring at source showed high levels of CO and NO 2 emissions to the atmosphere.
