Delhi’s air quality remains bad due to unfavorable weather conditions

Delhi's air quality remains severe due to unfavorable weather conditions, stubble burning

The city’s air quality was studied in the “very poor” category on Saturday morning, but it again slipped to the severe level in the evening.
On Sunday, the PM2.5 (particles in the air with a diameter of fewer than 2.5 micrometers) level was recorded at 299, while the PM10 (particles in the air with a diameter of less than 10 micrometers) level was recorded at 477, according to information from the CPCB. Twenty-eight areas in Delhi recorded air quality in the “severe” category, while seven areas served “very poor” air quality, according to the CPCB.
An AQI between 0 and 50 is considered “good”, 51 and 100 “satisfactory”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very poor”, and 401 and 500 “severe”. As per the Indian Institute of Tropical Meteorology, the increase in PM2.5 concentration is due to stable meteorological conditions trapping of the pollutants in Delhi (very less dispersion) and the significant increase in contribution from stubble burning. Stubble burning in neighboring states of Delhi on Thursday was the “largest-ever recorded” this year, the IITM had said Friday, adding that it could lead to a further deterioration in the already “severe” air quality of the national capital.

It commented about 2,100 fire counts were observed on Thursday over northwestern region of India. Delhi’s air quality has remained in the “severe” category for the past two days with the highest pollution level of the year recorded a day after Diwali on Thursday at an AQI of 642.
