Delhi breathes season’s worst air yet; Gurugram, Ghaziabad in ‘severe’ zone
Delhi witnessed the season’s worst air quality yet on Sunday (Air Quality Index: 366 µg/m3). The Central Pollution Control Board has asked people to not run and jog between November 1-10, predicting very high pollution during the period. The government’s air pollution research body, SAFAR, found stubble-burning contributing to 36% of Delhi’s pollution. Delhi state agencies are in ‘war mode’, as its air quality dropped from moderate (100-200 µg/m3) to severe (401-500 µg/m3) within ten days beginning October 12, which is the start of crop residue burning season.
The Supreme Court-appointed Environment Pollution Control Authority (EPCA) chief, Bhure Lal, found open waste and plastic burning at hundreds of locations in Delhi-NCR.
