This study demonstrates the relationship that exists between anthropogenic activities and the amount of gases that affect air quality emitted by area sources, fixed and mobile, calculated by means of an inventory and emission factors provided by the agency for the environmental protection of United States (US AP-42), in the districts of Yarinacocha, Calleria, and Manantay in Peru, through a prospective comparison for the year 2027. The results showed that the total emissions produced by different economic activities would deteriorate the air quality in the study area, and environmental problems such as smog and tropospheric ozone would be generated, which in turn directly affect human health.
