Aerobiological Study at the Uam-azcapotzalco, in Mexico City

Abstract

Abstract Aerobiological analyses allow us to evaluate air quality, if we live in a city like Mexico City, it is common to link it with industrial, commercial and vehicle use activities, among others, this fact is of such importance, since poor air quality can cause a wide variety of respiratory diseases depending on the time of exposure. The present work focused on carrying out an aerobiological study in six sites sampled at the UAM-Azcapotzalco. A total of 547 bacterial colonies and 297 fungal colonies were found. The maximum averages obtained for bacteria were in the dining room (22 UFC/m3) and the football field (48.75 CFU/m3), while for fungi the highest concentrations were recorded in the dining room (11.25 CFU/m3) and library (20.22 CFU/m3) areas. The Analysis of Variance showed that there are no significant differences for fungi and bacteria in the open and closed sites (p = 0.023), however the geospatial analysis helped to determine the areas with the highest density of microorganisms. The constant monitoring of bioaerosols, and the concentrations present in places with a high attendance of people, contributes to the generation of strategies to minimize the risks to human health, avoiding the generation of highly contagious diseases, such as the pandemic derived from SARS-CoV-2, among others. Finally, to minimize the microenvironmental conditions that allow the growth of microorganisms, we suggest the implementation of vegetal covers and natural surfaces inside and outside the work centers, as well as improvements in bio architecture, which would allow safe study and work.
