ST1-P2 Environmental Air Quality Conditions

ST1-P2 Environmental Air Quality Conditions
Definition

Air Pollution Index(API) is an indicator of the air quality condition based on the monitoring of the area. API is calculated based on the average of the parameters of solid air particles.

Justification

Airquality measurements are taken by DOE at several air quality monitoring stations throughout the nation. Data are given based on readings at research stations or the nearest stations every day within the area. Air quality parameters are taken into account when measuring the API such as average parameters of solid particles (PM10), Sulfur Dioxide (SO2), Carbon Monoxide (CO), nitrogen dioxide (NO2), and ozone (O3).

The higher the percentage of days in a year of good air pollution index readings show the more sustainable area.
