A thick blanket of haze continued to engulf the national capital on Sunday, a day after the air quality jumped to the "severe category", experts warned that the air quality is likely to remain the same as the pollution level returned to "very poor" category.
Smoke from firecrackers on Diwali has added to city's woes, the overall AQI in Delhi was recorded at 382 which falls in the very poor category, according to the data by SAFAR.
The PM2.5 (particles in the air with a diameter of less than 2.5 micrometres) and PM10 concentrations touched 226 and 339 respectively, both in the severe category, according to SAFAR data.
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".

Stubble burning in neighbouring states of Delhi on Thursday was the "largest-ever recorded" this year which might lead to a further deterioration in the already "severe" air quality of the national capital, the IITM said Friday.
