On the eve of Diwali celebrations, Delhi's air quality plunged into the 'severe' category, triggering health concerns across the national capital. Multiple monitoring stations recorded Air Quality Index (AQI) values soaring above 400, indicating hazardous breathing conditions for residents.
Pollution Levels Reach Critical Levels
The Central Pollution Control Board data revealed alarming readings across various locations. The 24-hour average AQI stood at a worrying 434 at 4 pm, with several areas experiencing even worse conditions. Meteorological factors including low wind speed and dropping temperatures have contributed to the rapid accumulation of pollutants.
Health Advisory for Delhi Residents
Medical experts have issued urgent health recommendations for the vulnerable population:
- Avoid outdoor physical activities and exercise
- Elderly, children, and those with respiratory conditions should remain indoors
- Use N95 masks when venturing outside
- Keep windows closed and use air purifiers indoors
Weather Conditions Worsen Situation
The deteriorating air quality coincides with unfavorable meteorological conditions. Calm winds and low ventilation index are preventing the dispersion of pollutants, creating a toxic blanket over the city. The minimum temperature recorded was 15.4 degrees Celsius, with humidity levels at 57% at 8:30 am.
Government Response and Measures
Authorities have heightened monitoring and are implementing measures under the Graded Response Action Plan (GRAP). The situation remains critical as the city prepares for Diwali festivities, which traditionally see a further deterioration in air quality due to fireworks.
Environmental scientists warn that without immediate and stringent measures, Delhi could face one of its worst pollution episodes this winter season, putting millions of residents at health risk.
