Air quality in Delhi worsened today and inched closer to the "severe" category with a sharp rise in the level of particulates through the day, according to official data.

The dip in air quality on Monday was reflected in the concentration of pollutants in the air. PM 2.5 levels have shot up to 461 in the area. The safe limit for PM2.5 and PM10 is 60 and 100 ug/m3 respectively.

The cleanest air day this year and since air monitoring began in Mumbai was recorded on October 12, when the AQI was 32 (good).

On November 14, Lucknow had earned the dubious distinction of being the most polluted city in the country with AQI of 484. It is classified as "very poor". The "severe" category starts from an AQI of 401 and above.

Yesterday's 24-hour average was 351. Play was halted for 17 minutes in the post-lunch session after the visitors, led by their skipper Dinesh Chandimal, wanted to leave the field of play complaining of severe pollution. The rest was in the "very poor" zone. AQI in neighbouring city of Vasundhara has also slipped into severe category with the PM 2.5 shooting up to 468.


An AQI level between 0-50 is good, 51-100 is satisfactory, 101-200 is moderate, 201-300 is poor.

Burgeoning air pollution in New Delhi has evoked anger and embarrassment in equal measure.

November witnesses extremely high levels of pollution as smoke from paddy residue burning reaches the city, aggravating the situation.

Delhi's air quality improved to "poor" on Wednesday, even as a toxic haze continued to envelop parts of the national capital with nitrogen dioxide (NO2) and other pollutants.
