At Chandni Chowk, the AQI with PM 10 was detected at 391 in the morning which stood at "Very Poor" category, while in the Mathura Road area the AQI with PM10 stood at 169 in "Moderate" category.

The AQI between the range of 51 to 100 is considered as satisfactory, 101-200 is moderate, 201-300 falls under the category of poor. It is a plan to counter pollution in Delhi which includes increasing bus and metro services, hiking parking fees and stopping the use of diesel generators when the air quality turns poor.

According to data by The Windfinder, a wind projection agency, direction of the wind is likely to change on Monday, increasing Delhi's air pollution and dipping AQI to "severe".

According to SAFAR, the stubble burning activity in Haryana, Punjab, and nearby border regions are nearly same as past three days but due to the change in circulation pattern and the wet transport path, their influence in Delhi region is negligible. It is expected to deteriorate to "very poor" category by October 22. Despite the increase in numbers, "contribution of stubble burning to PM2.5 levels in Delhi is only 7% till now", a CPCB official said. On Friday, SAFAR predicted that the share of pollution from farm fires would increase to 17% in Delhi Saturday.

And they say time involving clearing the property and the sowing period is too short to allow them to be stressing about Delhi's contamination.

Despite a ban on stubble burning in Punjab and Haryana, farmers continue to defy it amid lack of financial incentives.

The government has allocated $160 million for a subsidy scheme offering to cover up to 80 percent of a mulching and seed drilling machine, called "happy seeder machines", that farmers can mount on tractors to dispose of the paddy stalks and straw without burning them.

CPCB member secretary Prashant Gargava said a task force led by the pollution control body held a meeting Friday and recommended various pollution-controlling measures for Delhi-NCR.

"It is not that local pollution has increased, it is that weather has turned adverse and so, air pollution is again on the rise".

There is an active western disturbance over parts of Jammu and Kashmir, Uttarakhand, Punjab and Haryana. It is expected to reduce the impact of stubble burning slightly, he said.

Delhi air quality has seen a slight improvement in the last 24 hours.

IMD officials said that due to the occurrence of mist and high concentration of pollutants, the visibility levels at Safdarjung and Palam decreased to 1,500 metres at 8:30 am from 2,500 metres at 5:30 pm on Thursday.
