Bengaluru Chokes: Diwali Fireworks Spike AQI Dramatically
9 Nov
Summary
- Bengaluru's AQI surged from 53 to 129 post-Diwali, entering 'moderate' air quality.

- AQI worsened significantly after the permitted cracker-bursting window closed.
Bengaluru's air quality index (AQI) experienced a significant deterioration after Deepavali fireworks on Sunday night. The AQI escalated from 53 on Saturday to 129 by Monday, moving the city's air from a 'satisfactory' to a 'moderate' condition. This year's celebration saw nearly a 25% increase in AQI compared to the previous year.
The Central Pollution Control Board (CPCB) data revealed that the KSR railway station area registered the city's worst air quality on Monday morning, with an AQI of 228, mainly due to PM10 pollutants, placing it in the 'poor' category. Other congested areas like Silk Board also recorded high AQI levels, indicating widespread pollution.
Authorities noted that the AQI began worsening considerably after the permitted cracker-bursting window concluded at 10 pm, crossing the 100 mark by midnight. Experts emphasize that fine particles from fireworks remain harmful, particularly for vulnerable populations. The environment minister suggested stricter enforcement against those bursting crackers beyond designated hours.
