5. How Air Pollution is measured?
• Air quality is expressed in terms of AQI( Air Quality Index).
• It gives the index value that what is the current pollution status in the city and how
polluted the air currently is.
• There are eight pollutants whose concentration is measured and then based on
that (minimum three pollutants) AQI is calculated.
• As the AQI value increases, health impacts become serious.
