  In this scientific article, the data on air pollution by PM2.5 particulate
matter was evaluated in different locations in the city of Cusco with respect
to the Environmental Quality Indexes (INCA) of the Ministry of the Environment
of the Peruvian Government. The results show that air pollution in the city of
Cusco is an environmental risk problem. More than 84% of the monitored sites
have a bad rating (101-500), the corresponding color is orange. This result
shows that the air that citizens of Cusco breathe is of poor quality and the
population could experience health problems. The recommendation is to avoid
outdoor exercises and activities. In the district of San Jeronimo Cusco, the
average concentration has been 125 ug/m3, which corresponds to the INCA
interval of more than 125, within the red color threshold for care. The health
effects are described as chronic lung and cardiovascular diseases, and the
health authority should declare levels of alert. It has been concluded that
according to INCA, the air in the city of Cusco is of poor quality and falls
within the threshold of the Care State Value (VUEC).
