In Short

  • Delhi's AQI deteriorates to 406 after slight improvement on Friday
  • Stagnant winds and humidity worsen pollution levels in city
  • Government enforces staggered office timings, schools shift online

Delhi's air quality index (AQI) remained in the ‘severe’ category for the fourth consecutive day on Saturday, as dense smog engulfed the city. According to the Central Pollution Control Board (CPCB), the AQI was recorded at 406 at 8 a.m., after briefly improving to 386 (‘very poor’) on Friday evening.

The deteriorating air quality was attributed to stagnant wind speeds and high humidity levels, which trap pollutants close to the ground. North Delhi bore the brunt, with areas like Jahangirpuri (445), Burari Crossing (435), and Bawana (438) showing alarmingly high AQI readings.

Visibility at Indira Gandhi International Airport fell to 500 metres by 7:30 a.m., impacting flight schedules.

On Friday, Delhi Chief Minister Atishi announced staggered office timings for government employees to ease traffic congestion at peak hours and curb emissions. Schools have been instructed to transition to online classes, with campuses closed through Saturday.

To tackle the air crisis, the Delhi government has implemented emergency measures under Stage III of the Graded Response Action Plan (GRAP). These include a ban on private BS III petrol and BS IV diesel vehicles, restrictions on interstate non-electric buses, and a halt to private construction activities.

The Delhi Metro has added 60 extra trips daily to encourage the use of public transport and reduce pollution.

Delhi Environment Minister Gopal Rai expressed hope that increased wind speeds on Saturday will help improve air quality conditions.

With the city shrouded in smog, authorities have urged citizens to minimise outdoor activities and use masks when venturing out.
