New Delhi, November 17: In a major relief to residents of Delhi after almost a week, the air quality index (AQI) in the national capital improved from 'severe' to 'very poor' category on Sunday morning. According to System of Air Quality and Weather Forecasting And Research (SAFAR), the overall Air Quality Index (AQI) in the national capital was recorded at 365 which falls under 'very poor' category. The AQI in Lodhi Road in Delhi was recorded at 218 (PM 2.5) and 217 (PM 10) on Sunday morning. Mathura Road recorded a figure of 304, IIT Delhi docked at 324 and Airport Terminal 3 at 315. The AQI between the range of 51 to 100 is considered as satisfactory; 101-200 is moderate; 201-300 falls under the category of poor. While 300-400 is considered as 'very poor', levels between 401-500 fall under the 'hazardous category'.
The spike in air pollution in the national capital is primarily due to insufficient rainfall and low wind speed. A day after Diwali, the national capital turned into a apocalyptic city, as lack of breeze trapped the pollutants from firecrackers and stubble burning in neighbouring states added to the woes. The toxic air in the national capital has given itchy eyes, breathlessness and health issues to many residents in the National Capital Region.

According to a report by IANS, The effective stubble fire counts estimated on Friday, as per satellites, were negligible, only 2 but it is highly unreliable due to satellite capability to detect under dense cloud. Every winter season, parts of northern India suffer from a spike in toxicity in the air due to the change in weather and crop residue burning in the neighbouring states of Haryana, Punjab and Uttar Pradesh.
