With Delhi air quality slated to enter the “very poor” category on Tuesday, Chief Minister Arvind Kejriwal on Monday requested all state governments to take measures to prevent air pollution.

Addressing a press conference, CM Kejriwal said that in the last four months Delhi’s air quality has been in ‘Good’ category and the rise in the pollution levels recently is because of the smoke from the neighbouring states.

He further said that researches and media reports have stated a rise in pollution levels from last week of October to mid-November.

The coming days spell bad news for Delhi as the air quality entered the higher end of the poor category on Monday, with a worsening AQI score of 280, and is slated to enter the “very poor” threshold on Tuesday.

The forecast of the “very poor” air quality is predicted mainly due to changing local weather conditions.

According to pollution watch by Safar (System of Air Quality and Weather Forecasting and Research) India, developed by Ministry of Earth Science and Indian Institute of Tropical Meteorology, Pune the overall air quality of Delhi is in the higher end of the poor category.

“Further deterioration of the AQI is expected by October 15 to very poor category,” it said.

The stubble burning activity in Haryana, Panjab, and nearby border regions are moderate but increasing. Safar said it is not necessarily affecting Delhi air if distance weather conditions establishing transport pathways are not favourable.

The pollution causing score of PM 2.5 was at 114 in the poor category while PM 10 was at 208 in the moderate category.
