Delhi Air Pollution: A thick layer of haze engulfed Delhi on Sunday morning as the air quality in the national capital continued to remain in the 'severe' category, as per the Central Pollution Control Board. According to CPCB data, Delhi's overall AQI was recorded at 457 on Sunday morning.






In the wake of the rise in AQI, sprinkling of water was done in Delhi's National Zoological Park, as a measure against the worsening air quality in the national capital.






As per CPCB data, AQI in Delhi's Aya Nagar was recorded at 464, in Dwarka Sector-8 at 486, in Jahangirpuri at 463 and around IGI Airport (T3) 480.






On Saturday, Delhi Environment Minister Gopal Rai wrote to Chief Minister Arvind Kejriwal, seeking the suspension of Delhi Pollution Control Committee chairman Ashwani Kumar for "arbitrarily halting" the operation of a large smog tower installed at Connaught Place two years ago to mitigate air pollution.


In the letter to Kejriwal, Rai also sought disciplinary action against the project in-charge, Anwar Ali, whom the minister accused of changing his stance on the smog tower's effectiveness under pressure from Kumar. Rai mentioned that two smog towers were installed in Delhi -- at Connaught Place under DPCC and at Anand Vihar under the Central Pollution Control Board -- following the Supreme Court's directions.
