The task force also warned that at beginning of November the situation may get further deteriorated on account of localised emissions on festival? and regional contribution due to stubble burning.
Stubble burning from Punjab and Haryana Saturday caused 32 per cent of pollution in Delhi, according to a report by the SAFAR.

A Supreme Court-appointed Environment Pollution Authority warned on Thursday that air pollution in the capital region is likely to peak from next week as toxic fumes from the burning of agricultural fields in the neighbouring northern states.

Meanwhile, an inspection team led by Delhi Environment minister Imran Hussain Friday found "serious violations" in norms for dust control at the Pragati Maidan redevelopment site, following which the minister directed pollution control authorities to take strict action, the city government said.

The assessment is based on the data from IITM-Pune, he said.
Out of 48 monitored station across NCR (including Delhi), only four had "moderate to poor" air quality while 18 stations has "severe or severe-plus" air quality and 26 were "very-poor". "The dominant pollutant of AQ Index is PM2.5 and PM10", the IITM said.
