Concentración de monóxido de carbono, dióxido de nitrógeno y dióxido de azufre en Esmeralda, Ecuador.

Abstract

For a few years, environmental pollution due to greenhouse gases has been a source of constant concern for society, which has become aware of the risks that this issue entails for the life of living beings on the planet. The objective of this work was to determine the concentrations of carbon monoxide, nitro-gen dioxide and sulfur dioxide in points of higher vehicular density in the city of Esmeraldas. For the measurement of gases, three points in the city were chosen: ave. Christopher Columbus “outdoor sector; bird. Jaime Hurtado (CODESA sector) and Ave. Simon Bolivar (downtown). Measurements were made with specific Drager colorimetric tubes for the measurement of each of the gases of interest. As a result, it was obtained that the concentration of the gases determined was in no case above the permissible limit, carbon mo-noxide being the gas found in the highest concentrations in the three points evaluated and the maximum value (2845.5μg/m3). it was detected at point 3, which coincides with being the point of greatest vehicular congestion at the time studied. As a conclusion, we can state that the levels of environmental pollution were evaluated at three points in the city of Esmeraldas, Ecua-dor, produced by carbon monoxide, nitrogen dioxide and sulfur dioxide gases emitted by the circulation of vehicles, finding, in all cases, concentrations below the permissible limits, being CO, in point 3, the gas for which the hi-ghest concentration values of 2845.5μg/m3 (56.9) were obtained, below the maximum permissible value of 40000μg/m
