The national capital’s air quality index worsened and reached to 'very poor' category at 304 on Tuesday morning. The northwest district recorded the most polluted air, according to the Central Pollution Board's data. Tuesday was the season's worst air day so far.
The air pollution reaches to ‘Worse’ category in Delhi-NCR every winter. When the pollutants from stubble burning combine with the suspended water droplets in the lower atmosphere to form a thick blanket of noxious smog, they create health hazards for the residents.
The India Meteorological Department says the spike in pollutants is a result of low wind speeds, along with an increase in stubble burning in the neighbouring states of Punjab and Haryana.
