Abstract
Air quality is increasingly altered by different pollutants due to the increase in anthropogenic activities which emit different pathogens into the air, such is the case of microorganisms that can be transported through the air and affect people's health. In this research, an evaluation of the microbiological contamination of the air in the city of Tingo Maria was carried out using Petri dishes with Sabouraud Glucose Agar and Plate Count culture media for fungi and bacteria, respectively, which were placed in 12 strategically selected points of the city. From the results of the determination of the number of colonies by the method of counting the most probable number, it was determined that the highest concentration for bacteria was found in the sample MB10 located at Av. Raymondi with Jr. Julio Burga with a concentration of 84*103 colonies mo/cm3 and for fungi this was found in the sample MF7 located in the Plaza de Armas: Ovalo de la Alameda Peru with a concentration of 34*103 Colonies mo/cm3; the lowest concentration for bacteria was found in sample MB3 located in Jr. Callao block 4 with 5*103 Colonies mo/cm3 for fungi the lowest concentration was found in samples MF1, MF2 and MF8 with a concentration of 4*103 Colonies mo/cm3. In addition, by counting the concentrations of all the samples, the areas with the highest concentration for both bacteria and fungi were zoned.
