The air quality remained in the “hazardous” category in several parts of Delhi on Saturday morning, with the air quality index (AQI) registering above 600 in Anand Vihar.
Two days after Diwali, Delhi’s air quality remains in the “hazardous” category in several parts of the city, with the air quality index (AQI) registering above 600 at Anand Vihar and Faridabad.
The overall AQI clocked at 533 for the national capital, according to data released by the System of Air Quality and Weather Forecasting and Research (SAFAR) on Saturday morning.
On Saturday, the PM10 levels at Connaught Place and Jantar Mantar stood at 654 and 382 respectively. Meanwhile, PM2.5 levels were at 628 in Connaught Place, 341 near Jantar Mantar, and 374 near ITO, according to ANI.
The air quality in several parts of the city had deteriorated to “hazardous” category on Friday, a day after Diwali. A thick blanket of smog engulfed the national capital on Friday morning as several people reportedly complained of itchy throat and watery eyes.
The air quality at Janpath was recorded in the “hazardous” category early on Friday, with the particulate matter (PM) 2.5 concentration at 655.07, according to news agency ANI.
An AQI between zero 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’.
Experts said the air quality turned severe due to unfavourable meteorological conditions — calm winds, low temperature and low mixing height — and a poisonous cocktail of emissions from firecrackers and stubble burning, PTI reported.
Air quality forecast agency SAFAR had said that the PM2.5 concentration would shoot up rapidly on Friday, with the AQI even crossing the 500 mark. Relief is expected only from the evening of November 7 but AQI will fluctuate within the “very poor” range, the air quality forecast agency said.
