Delhi's AQI Hits 743 After Diwali, Highest in India

Delhi registered an alarming AQI of 743 on the day following Diwali celebrations, the highest recorded in the country. The smog, a mix of particulate matter and gases, has pushed the air quality index to hazardous levels. Nearby cities also saw elevated readings, with Lucknow at 493 and Indore at 449. Health officials have warned that such levels can cause respiratory distress, especially among children and the elderly. Authorities advise people to limit outdoor activities, wear masks, and keep indoor air purifiers running. The spike is attributed to fireworks, increased vehicular traffic, and industrial emissions during the festive period.
