"Pollution on Diwali has gone down and was the lowest in the last five years. But our target is to eradicate it," Kejriwal said.
He also appreciated people for their efforts to reduce pollution.
Speaking about the laser show organised by state government during Diwali, he said people had shown good response and the government was planning to organise it at more venues next year.
On Monday morning, PM 10 (particulate matter) in Delhi's air was at 476 in the severe category, according to the System of Air Quality and Weather Forecasting and Research (SAFAR).
The SAFAR had predicted that the air quality would be touching severe levels on Monday morning, but the peak level of PM 2.5 would be the lowest in the past 3 years after 2015.
There are six AQI categories good-satisfactory, moderately polluted, poor, very poor, and severe. Each of these categories is decided on the ambient concentration value of air pollutants and their likely health impacts.
On a question on an upcoming T20I cricket match, Kejriwal expressed his the hope that the pollution would not affect the India-Bangladesh match at the Arun Jaitley Stadium on Sunday. Matches had been held at the stadium in similar conditions before this too, he added.
