Evaluation of Tropospheric Ozone concentration in two Urban Roads of Manaus - Am

This main objective is to evaluate the concentration of Ozone (O3) in the low troposphere of two main urban roads of Manaus, thus identifying the possible impacts of this element on human health and the environment. For this work, weekly data were collected in September, a period characterized as dry in the region. The data were treated according to the hourly average of the concentrations that were established from 10 to 15h UTC, based on the values collected by RESOLUTION CONAMA 491/2018 that presents the criteria of air quality standards. The results demonstrated high peaks in the ozone concentration, but were within compliance, since in most of the monitoring time the concentrations were in accordance with the legislation in force.
