The methodology used was experimental type whose data were processed using descriptive statistical techniques. The results indicated that the gases under study are in the permissible levels by current legal regulations and recommended continued efforts to mitigate the agentsair pollutants in the city. Keywords: Air Quality, CO, CO2, Instrumentation, Descriptive Statistics, Sustainability. I. INTRODUCTION Colombia ranks second among the 12 different mega nations, with an area of 0.7% of the surface of the planet, with 10% of the flora and fauna of the Earth, according to the Research Institute of Biological Resources Alexander von Humboldt likewise alarms are on due to high pollution since it is a problem that is increasing, according to (wHO) Colombia is the second country in Latin America with major environmental problems. Global warming is a problem that currently increases due to the different sources of contamination, this is produced one of the greatest environmental problems of air pollution, which occurs naturally and / or artificially. Starting from this point, it is important to know in depth each of the variables and factors involved in their development. The direct consequences that occur in humans due to high levels of air pollution on health are observed. According to official figures, worldwide 3.8 million people die every year from diseases related to pollution of the air, which are pneumonia (27%), stroke (18%), ischemic heart disease (27%), obstructive lung disease occur chronic (20%) and lung cancer (8%) (World Health Organization, 2018). According to the information above, they are notable attempts to lessen the overall impact of air pollution in Colombia. However, these attempts are premature and insufficient, it is necessary to implement better technologies in the major generating sources of pollution such as industry and transport, able to consolidate a culture for the care of the air is another important aspect that can lead to lower economic indices and current health of the country. Likewise, the purpose of the investigation focused enn determine levels of gaseous pollutants CO, NO2, CO2, and O3 present in villavicención, Meta Colombia. II. BACKGROUND Among the different models to analyze data sets referring to modeling variables contamination of the air for a case study for the city of Medellin (Colombia), where regression models uses of the soil worked in the estimate is Local monthly concentration of pm10, their results were related to indicate the importance of the proper choice of the explanatory variables and access to them for the efficiency of the mathematical model is optimal, likewise, the direct correlation is denoted the closeness between the main roads and traffic density with the concentration of the pollutant PM10 a measurement point [1],statement is consistent with the one in the city of Cali (Colombia) which states that the dynamics of vehicular traffic is primarily responsible for the pollution of air particulate matter PM10, an approach that was developed by using a Spline method modeling the daily behavior of said contaminant [2]. Likewise, in another study conducted in the same city, exactly in the districts 7 and 8, where he worked with a logistic regression model to assess environmental conditions and pollution under which the risk of presence of contamination Total Suspended Particles (PST) is higher. Worked as variables total suspended particles (TSP) and PM10 particulate material where, from the results of PM10 is possible to obtain a value for PST that can serve as reference for other studies. Moreover, the influence of the climate variable in the presence of pollution that ultimately supported by the model created, you can obtain a measure of the risk of the presence of contamination by PST in the study area is ratified [ 3].
