On Wednesday, the Swiss monitoring organization IQAir reported AQI levels as high as 1,133 in some parts of Delhi, indicating ‘hazardous’ air quality, with PM2.5 particulates identified as the main pollutant.
The smog has been attributed to factors including seasonal stubble burning in Punjab and Haryana, and stagnant weather conditions that trap pollutants in the air.
The CPCB defines AQI levels as follows:
- 0-50: Good
- 51-100: Satisfactory
- 101-200: Moderate
- 201-300: Poor
