On Monday morning, Delhi’s air quality showed a small improvement. The Air Quality Index (AQI) averaged 264 at 6 a.m., down by almost 90 points from the previous day. However, the air quality still fell in the “very poor” category, which remains harmful to health, according to the IQair website.
Winds Boost AQI, but Pollution Remains High
The recent improvement in air quality results from a slight increase in wind speed. Over the past two days, stagnant air worsened pollution, driving AQI levels higher.
Pitampura and Defence Colony See Varied AQI Levels
Pitampura’s AQI stood at 167 early Monday, showing better air quality than other parts of the city. However, areas like Defence Colony recorded AQI levels over 320, indicating a worsening trend in pollution.
Pollution Worsens with Calm Winds
On Sunday, calm winds kept pollutants trapped, and air quality in Delhi dropped to “very poor.” The city’s AQI climbed to 355 by 4 p.m., compared to 255 on Saturday, reported the Central Pollution Control Board (CPCB).
Out of Delhi’s 40 monitoring stations, 37 reported data, with three—Bawana, Burari, and Jahangirpuri—showing “severe” pollution levels.
Delhi Takes Steps to Control Pollution
With Diwali and winter approaching, the Delhi government has introduced several pollution-control measures. These steps include promoting public transport, reducing dust, and banning firecrackers during the festival.
The Centre’s Graded Response Action Plan (GRAP) is also in effect. Since October 21, the Commission for Air Quality and Management (CAQM) has activated GRAP Stage 2, targeting AQI levels between 301 and 400.
Firecracker Ban to Curb Pollution
Delhi-NCR has banned traditional firecrackers since 2020, allowing only “green crackers” without barium salts. To prevent misuse, officials continue to impose a blanket ban during winter.
The Delhi Pollution Control Committee (DPCC) banned the manufacture, sale, storage, and online delivery of firecrackers until January 1, 2025. Yet, cross-border smuggling and doorstep delivery of banned firecrackers may still add to Delhi’s pollution issues.
