New Delhi: Delhi's air quality has plunged to 'severe' category, which carries the risk of affecting people's respiratory system, as smoke caused by fireworks, as part of Diwali festivities, blanketed the national capital.
It had forecast that the city's air will be severely polluted on October 30 and 31.
The Central Pollution Control Board's (CPCB) monitoring stations, in areas like R K Puram, Anand Vihar, Mandir Marg and Shadipur, had similar 'severe' readings as well.
People have been advised not to go outdoors when air quality turns 'severe' as it has adverse effect especially on children, elders and those having heart or lung diseases.
Delhi Pollution Control Committee's (DPCC) real-time readings were also indicative of the increasing levels of pollution with the rise in the numbers of crackers going off.
By 8pm, DPCC's Punjabi Bagh and Anand Vihar stations had PM 2.5 readings of 202 and 240 micrograms per cubic metre respectively, while PM 10 had risen to 429 and 766 micrograms per cubic metre.
Pollution peaks in the national capital during Diwali as a hazardous mix of noxious gases and respirable pollutants hang very close to the surface due to low temperature and near-stagnant wind movement.
