An AQI between 201 and 300 is classified as “poor”, between 301 and 400 is classified as “very poor”.
It was only by Friday afternoon, the AQI improved to 108, which was moderate, according to Safar. The AQI measures combination of pollutants including PM10, PM2.5, NO2, SO2, CO, O3, NH3, and Pb. Concentration of PM 2.5 particles, considered to be most deadliest polluting agents, are linked to firecracker residue, shot up to 402 ugm3 at Hadapsar, while PM 10 was 167 ugm3 on Thursday, second day of the three-day festival.
