According to the CPCB, the AQI in the Lodhi Road area was recorded at 438, in Jahangirpuri at 491, in the RK Puram area and in IGI Airport (T3) at 486 and 473 respectively.
Air Quality Index (AQI) is a tool for effective communication of air quality status to people in terms, which are easy to understand. It transforms complex air quality data of various pollutants into a single number (index value), nomenclature, and colour.
The AQI from 0 to 100 is considered good, while from 100 to 200 it is moderate, from 200 to 300 it is poor, and from 300 to 400 it is said to be very poor and from 400 to 500 or above it is considered as severe, which affects healthy people and seriously impacts those with existing diseases.
