Delhi's Air Quality and Post-Diwali Impact
Residents in Delhi experienced a significant decline in air quality following Diwali celebrations, as indicated by air quality index (AQI) readings.
Air Quality Index (AQI) Readings
- The AQI on the morning of October 22 was recorded at 345, categorized as ‘very poor’ by the Central Pollution Control Board (CPCB).
- Parts of Delhi, including Ashok Vihar, Bawana, and Dilshad Garden noted an AQI of 380 at 6.15 am.
- Majority of Delhi recorded AQIs ranging from 300 to 400, while areas like DTU, IGI Airport, and Lodhi Road had an AQI of less than 300, or ‘poor’.
- On October 21, some regions exceeded AQI levels of 500 due to violations of firecracker regulations issued by the Supreme Court.
Reasons for Air Quality Deterioration
- The burning of firecrackers beyond the set two-hour limit (8 pm to 10 pm) significantly contributed to the air pollution.
- Annual concerns about air quality in Delhi are exacerbated by stubble burning in surrounding states, especially during periods of low wind speeds.
Incidents and Emergency Services
- Over 250 people suffered burn injuries during Diwali, with a surge in hospital cases, primarily due to firecrackers.
- Safdarjung Hospital reported the highest number of burn cases at 129.
- The Delhi Fire Services (DFS) received 269 emergency calls on Diwali night, reflecting a 15% decline from the previous year’s 318 calls.
