The air quality index is used to measure the pollution level in air and is an indicator of how clean or polluted the air. It also indicates the health effects of breathing polluted air.
An AQI of 51-100 is considered ‘satisfactory’ and is linked to minor breathing discomfort to sensitive people. Further, AQI between 101 and 200 is considered ‘moderate’ and is associated with breathing discomfort to the people with lung, heart disease, children and older adults.
