On November 18, 2024, Delhi's AQI hit a staggering 481, the worst of the season. This level falls into the "severe-plus" category, a condition far worse than the already hazardous "severe" category
An AQI of 481 can cause severe health problems for everyone, not just those with pre-existing conditions. Doctors advise limiting outdoor activity and taking precautions for respiratory issues
To curb the pollution, the Delhi government has implemented Stage IV of the Graded Response Action Plan (GRAP). This includes strict measures such as banning non-essential truck traffic, halting construction projects, and promoting remote working for offices
The toxic smog has reduced visibility to dangerous levels, affecting air travel and local transport. The morning of November 18 saw visibility drop to just 150 meters at Safdarjung Airport
Delhi's pollution crisis is not isolated. Neighboring cities in South Asia, including Lahore and Dhaka, are also facing hazardous air quality, exacerbating the regional environmental emergency
For those living in the National Capital Region (NCR), experts suggest staying indoors, using air purifiers, and wearing N95 masks when going outside. Schools have shifted to online classes for most students to reduce exposure
