Air pollution in Delhi was off the charts on Tuesday, a Hindustan Times air-quality monitoring system showed, indicating that the peak pollution season in the city has begun.
The worst air quality was reported from west Delhi’s Punjabi Bagh – where the air quality index (AQI) was 500, the maximum possible rating of “severe” – followed by Anand Vihar in east Delhi that displayed an AQI of 467 and an identical rating.
Air quality is rated by AQI within a range of 0 (good) to 500 (severe). Only one of 10 spots in Delhi where HT’s monitoring system is installed reported “satisfactory” air quality – east Arjun Nagar with 91.
Delhi’s air is considered the worst in the world that gets worse in the winter months because of a combination of no rainfall, lower wind speeds and crop burning in the national capital region and neighbouring states.
