Delhi Chokes: AQI Plummets to 'Very Poor' Ahead of Diwali 2025

As Delhi inches closer to the festive fervor of Diwali, a dark cloud of pollution once again threatens to overshadow the celebrations. On October 19, 2025, the national capital's air quality significantly deteriorated, with the Air Quality Index (AQI) plunging deep into the 'very poor' category across numerous monitoring stations.

This alarming decline signals a growing environmental crisis that demands immediate attention and collective action.

Data from the Central Pollution Control Board (CPCB) revealed concerning figures for key areas. Anand Vihar recorded an AQI of 385, while Wazirpur stood at a staggering 392. RK Puram wasn't far behind with 378, and even the relatively greener area of Mandir Marg registered an AQI of 365.

These numbers, all hovering dangerously close to the 'severe' threshold of 400, paint a grim picture of the air Delhiites are forced to breathe. An AQI between 301 and 400 is classified as 'very poor,' which can cause respiratory illness upon prolonged exposure, and severely affect people with existing diseases.

Experts attribute this pre-Diwali pollution surge to a confluence of factors.

Stubble burning in neighboring states continues to be a major contributor, with plumes of smoke traveling towards Delhi due to changing wind patterns. Vehicular emissions, particularly from older vehicles and during peak hours, also play a significant role. Industrial pollution, construction dust, and the burning of waste further exacerbate the situation.

As temperatures drop and wind speeds reduce, pollutants tend to accumulate closer to the surface, forming a dense, hazardous blanket over the city.

The health implications of such high pollution levels are profound. Residents, especially children, the elderly, and those with respiratory or cardiovascular conditions, are advised to take extreme precautions.

Medical professionals warn of increased cases of asthma attacks, bronchitis, and other respiratory ailments. There is also a heightened risk of long-term health issues, including lung damage and heart disease, from sustained exposure to such toxic air.

In response to the deteriorating air quality, authorities are expected to implement or intensify measures under the Graded Response Action Plan (GRAP).

This includes bans on certain construction activities, restrictions on polluting vehicles, and advisories for public transport usage. However, the effectiveness of these measures often depends on strict enforcement and public cooperation. With Diwali just around the corner, concerns are mounting about the potential spike in pollution due to firecrackers, despite ongoing campaigns advocating for cracker-free celebrations.

The current situation serves as a stark reminder of the urgent need for sustainable solutions.

This includes promoting cleaner public transport, investing in renewable energy, improving waste management, and encouraging practices that reduce emissions at every level. While government initiatives are crucial, individual responsibility – choosing greener commutes, reducing energy consumption, and supporting eco-friendly alternatives – will be vital in safeguarding Delhi's breathable future.
