'New Delhi again topped a real-time list of the world's most polluted cities compiled by Swiss group IQAir, which put the Indian capital's AQI at 640 in the "hazardous" category on Friday, followed by 335 in the Pakistani city of Lahore.'
640 is ridiculous!
'"This pollution level is here to stay for the next two to three weeks, aggravated by incidents of stubble burning, slow wind speed and cooling temperatures," said Ashwani Kumar, chairman of the Delhi Pollution Control Committee.
Farmers in the northern states of Punjab, Haryana and Uttar Pradesh typically burn crop waste after harvesting in October to clear their fields before sowing winter crops a few weeks later.'
