Resumen

Objetive: to evaluate the concentration levels of CO, CO2and H2S in the air in different areas of the district of Alto Selva Alegre and to elaborate a diffusion map of the concentration levels of these gases in the air, with the purpose of proposing air quality mitigation plans for the concentration of gases. Theoretical framework: air quality is affected by the emission of different gases into the atmosphere by both anthropogenic and natural activity. Method/design/approach: used in the gas monitoring involved the use of Aeroqual S500 digital portable equipment at 09 points distributed in the areas with the highest vehicular traffic. At each monitoring point, the concentration levels of the three gases were recorded and then compared between the morning and afternoon hours. Results and conclusion: The results showed that: Chilina-Cayma Bridge crossing, presents a higher concentration of carbon monoxide and hydrogen sulfide, registering an average 4453.50 μg/m3in 8 hours and average 37.75 μg/m3, respectively. In Brazil-Commissariat Avenue, there is a higher CO2concentration, registering an average 262.86 mg/m3. The maps of CO, CO2and H2S concentration diffusion show variations between zones and sampling hours (morning and afternoon). It is concluded that the presence of gases generates consequences on people's health. Research implications: Analysis of gas concentrations influencing air quality and their effect on human health Originality/value: Maps of the behavior of gases that affect air quality as a result of the activity of the vehicle fleet.
