To be specific, twenty-eight areas in Delhi recorded 'poor' air quality, six recorded 'very poor' air quality, while two areas recorded 'moderate' air quality on Wednesday morning.
The air quality in the national capital region has been deteriorating from the past few days with authorities attributing the continuous pollution to the change in wind direction. The wind, which is now blowing from the direction of stubble burning areas of Punjab and Haryana, will be bringing the influence of biomass burning pollutants in Delhi-NCR till Wednesday, according to the Indian Institute of Tropical Meteorology.
The air quality will further deteriorate to 'severe plus emergency' category on November 8 if "partial toxic crackers" are burned on the day of Diwali, the Centre-run System of Air Quality Forecasting and Research (SAFAR) warned. While the PM 10 is expected to reach 575, the PM 2.5 may reach 378 a day after Diwali, recording the worst air quality of the year.
In the wake of the current scenario, watchdog CPCB has also recommended a ban on the entry of trucks into the city between November 8 to 10. Delhiites have been requested to help in reducing local sources of pollution by celebrating a cracker-free Diwali on Wednesday.
