Following the Diwali celebrations, Delhi's air quality index reached 413 at 1 a.m., according to the CPCB, indicating hazardous pollution levels.
The Central Pollution Control Board (CPCB) recorded an Air Quality Index (AQI) of 413 for Delhi at 1 a.m. on the night after Diwali celebrations, crossing the 400‑mark that signals severe health risks. The spike was attributed to extensive firecracker use across Delhi and the National Capital Region, which released large quantities of particulate matter and toxic gases into the atmosphere.
Experts warned that such high AQI levels can aggravate respiratory conditions, especially for children, the elderly and those with pre‑existing heart or lung diseases. The CPCB advised residents to limit outdoor activities, keep windows closed, and use air purifiers where possible.
Authorities in the capital have already issued advisories for the next few days, urging the public to wear masks and follow precautionary measures as the pollutant concentration is expected to remain elevated until weather conditions improve.
The incident underscores growing concerns over the environmental impact of firecracker usage during festivals, prompting calls for stricter enforcement of existing bans on illegal fireworks.
