According to the System of Air Quality and Weather Forecasting And Research (SAFAR), the level of particulate matter with a diameter of 2.5 microns or less (PM2.5) and PM10 were in the 'very poor' zone and were the major pollutants.

"Mostly calm or slow winds during the night are unfavourable for effective dispersion of pollutants. The air quality is likely to improve marginally but remain in the upper end of the 'very poor' category on November 27 and 28. The air quality is likely to remain in the 'very poor' category for the next five days. A gradual improvement is likely from November 27 till November 30, with PM2.5 expected to be the predominant pollutant," Air Quality Early Warning System for Delhi (Ministry of Earth Sciences) said in its bulletin.
