Abstract: The study presents the analysis of air quality presented in the city of Villavicencio in the Department of Meta in Colombia. Being a city with a dynamic growth the air pollution is more evident every day. Therefore, a correlational study was carried out between the particulate matter and the physical environmental variables. It also presents a diagnosis of the perception of air quality by the population under study. This analysis allowed to find the mathematical models and their respective dependence based on linear correlation. It was determined that the behavior of the Particulate Matter (PM 2.5 and PM 10) within the study zone is in the limits with respect to national and international regulations.
