Alarm bells ring as Delhi’s AQI enters ‘severe’ zone
Hindustan TimesDelhi’s air quality continued its alarming descent deep into noxious levels, as the pollution climbed into the ‘severe’ zone on Monday evening, stoked by smoke from farm fires in Punjab and helped by calm winds and dipping temperatures in the city. Though the Central Pollution Control Board’s daily 4pm bulletin logged an air quality index of 392 on Monday, worse than 352 a day ago and the second-highest so far this season, this number climbed hour-on-hour and crept to 403 at 10pm, according to the agency’s Sameer app. To be sure, Delhi’s AQI is yet to touch severe on the 4pm bulletin, the value considered for air quality records, so far this season. On Monday, Punjab recorded 2,131 farm fires, showed state government data, the most in a day so far this season, with experts and officials warning that this number will only climb over the next few days, with nearly half the state’s paddy fields still to be cleared for the winter crop.
