Delhi's Air Quality Plunges to 'Severe' Category, Triggering Health Warnings and Government Action

Delhi Grapples with 'Severe' Air Quality

New Delhi, India – The air quality in India's capital, Delhi, has sharply deteriorated, with the Air Quality Index (AQI) surpassing the 400-mark and categorizing the city's air as 'severe' on Saturday, November 8, 2025. This toxic haze has pushed the national capital into the 'red zone,' making it one of the most polluted cities in the country. The 24-hour average AQI, measured at 4 pm, stood at 361, worsening to 372 by 6 pm, according to data from the Central Pollution Control Board (CPCB).

Several areas within Delhi recorded AQI levels well above 400, including Wazirpur (420), Burari (418), Vivek Vihar (411), Nehru Nagar (406), Alipur (404), and ITO (402). The National Capital Region (NCR) also experienced poor air quality, with Noida recording an AQI of 354, Greater Noida 336, and Ghaziabad 339, all falling into the 'very poor' category.

Alarming Health Impacts and Contributing Factors

The 'severe' air quality poses significant health risks to residents. Doctors warn that the toxic air can damage the heart, immune system, and mental health. Fine particulate matter, particularly PM2.5, can deeply penetrate the lungs and enter the bloodstream, exacerbating respiratory problems, heart diseases, strokes, and lung cancer. Long-term exposure has been linked to irreversible lung damage in children, with studies indicating that 2.2 million children in Delhi have already suffered such damage.

The current pollution crisis is attributed to a confluence of factors:

• Stubble Burning: Satellite imagery on Friday indicated 100 incidents of stubble burning in Punjab, 18 in Haryana, and 164 in Uttar Pradesh. This practice alone accounted for nearly 30 percent of Delhi's pollution.
• Vehicular Emissions: Road transport contributes significantly, accounting for approximately 15.2 percent of the city's pollution.
• Construction and Demolition Dust: Rapid urban expansion and ongoing construction activities generate substantial dust, further degrading air quality.
• Industrial Emissions: Factories and power plants in and around the NCR release various pollutants.
• Meteorological Conditions: Cold temperatures and stagnant winds during the winter months trap pollutants close to the ground, preventing their dispersion and leading to the formation of dense smog.

Government Implements Emergency Measures

In response to the escalating crisis, authorities have activated Stage II of the Graded Response Action Plan (GRAP). The Delhi government has announced several measures to mitigate pollution and reduce vehicular traffic:

• Revised Office Timings: From November 15, 2025, to February 15, 2026, government offices will operate with staggered timings. Delhi government offices will function from 10 am to 6:30 pm (previously 9:30 am to 6:00 pm), and Municipal Corporation of Delhi (MCD) offices from 8:30 am to 5:00 pm (previously 9:00 am to 5:30 pm).
• Vehicle Restrictions: The entry of all non-Delhi registered BS-III and below-standard commercial goods vehicles into Delhi has been banned since November 1. The New Delhi Municipal Council (NDMC) has also doubled parking fees across the city.
• Anti-Smog Measures: The Public Works Department (PWD) plans to hire 200 truck-mounted anti-smog guns for five months, and buildings with G+5 floors or above are mandated to install these devices. The Delhi government has also conducted two rounds of cloud-seeding operations.
• Intensive Road Cleaning: A comprehensive road-cleaning and maintenance drive, led by the PWD, involves 200 maintenance vans tasked with cleaning 1,400 km of roads daily.

Residents have been advised to wear masks and avoid unnecessary outdoor activities to protect their health. Forecasts from the Air Quality Early Warning System for Delhi suggest that the city's air quality is unlikely to improve significantly in the coming days and is expected to remain in the 'very poor' category.
