Abstract: The impacts of air pollution on the environment have been studied for many years by the scientific community. Increasing evidence points to air pollution as one of the main causes for the development of respiratory diseases, thus impacting the well-being of the population. Air pollution negatively affects the respiratory health of both adults and children. In this context, children are more susceptible than adults due to their immune system and immature lungs. Air quality is affected by a range of pollutants, including particulate matter (PM2.5 and PM10) and gaseous pollutants (NO2, SO2, CO and O3). PM10 exposure has been identified as a statistically significant risk factor for an increase in the number of asthma-related emergency room visits in children, NO2 and SO2 are correlated with moderate/severe asthma irritations in children, CO with moderate exacerbations /severe asthma in adults and O3 increases the risk of current asthma, with persistent evidence that it may directly cause asthma exacerbation in children. Asthma is a chronic disease characterized by inflammation of the airways, with an estimated prevalence of between 1-18% of the population, varying for each country. Historically, epidemiological studies have shown that the prevalence of asthma in children living in the city of Vitória, capital of the state of Espírito Santo, Brazil, is higher than the national average. This study sought to analyze data collected through a longitudinal study with 200 children aged between 8 and 14 years, members of the ASMAVIX Project. The main objective is to estimate the concentrations and inhaled doses of the main pollutants, comparing the estimated results with the results collected through monitoring stations and the use of personal monitors (Ogawa Passive Sampler). For this, the use of the CALPUFF Model was adopted due to the climatic and geographical conditions of the city of Vitória. When calculating the inhaled dose, different approaches verified in the literature were tested, using different reference values for the parameters of ventilation rate, indoor-outdoor ratio, among others. Furthermore, correlation analysis is being developed to compare pollutant concentrations with the health effects and sociodemographic characteristics of individuals participating in the project.
