Delhi Chokes: Air Quality Plummets to 'Very Poor' as Diwali Looms Large

Delhi-NCR finds itself enveloped in a thick, hazardous haze, with air quality spiraling into the 'very poor' category just ahead of the much-anticipated Diwali festival. Residents are bracing for a challenging period as the air quality index (AQI) breaches alarming levels, prompting grave concerns among health experts and environmentalists alike.

The latest data reveals a disturbing trend, with several monitoring stations reporting AQI figures well above 300, a level considered detrimental to public health.

As of October 21st, 2025, the air quality in the national capital region paints a grim picture. Key areas such as Anand Vihar, Wazirpur, and RK Puram have consistently registered AQI values hovering between 350 and 390.

This signifies a significant concentration of pollutants that can lead to respiratory illnesses and exacerbate existing conditions. The 'very poor' classification means that prolonged exposure to this air can cause respiratory illness on a large scale, even in healthy individuals.

Multiple factors conspire to push Delhi's air into this dangerous zone.

The notorious practice of stubble burning in neighboring states continues to be a major contributor, with winds carrying dense plumes of smoke directly into the NCR. Vehicular emissions, industrial pollution, and construction dust add layers to this toxic cocktail. However, the impending Diwali celebrations bring an added layer of apprehension.

Despite bans, the use of firecrackers historically leads to a sharp spike in pollution levels, further deteriorating an already precarious situation.

Environmental agencies and local authorities are on high alert, issuing advisories for residents, especially the vulnerable populations. Children, the elderly, and individuals with pre-existing respiratory and cardiovascular conditions are particularly susceptible to the adverse effects of this polluted air.

Experts warn against outdoor activities during peak pollution hours and recommend the use of N95 masks to mitigate exposure to fine particulate matter (PM2.5 and PM10).

The current scenario underscores the urgent need for stringent measures and sustained efforts to combat air pollution. While short-term interventions are crucial, long-term strategies focusing on sustainable agricultural practices, cleaner public transport, and stricter industrial emission norms are paramount to ensure clean air for Delhi-NCR's future generations.

The coming days leading up to and immediately after Diwali will be critical in determining the full extent of this environmental crisis.
