New Delhi – In a disturbing turn of events,data released on Saturday,November 2,2025,reveals that all Forty cities globally with the worst air quality are located within India. This alarming statistic underscores a rapidly escalating environmental health crisis impacting millions across the nation. The Air quality Index (AQI) readings, taken at 8:30 AM local time, show that numerous towns in northern India have reached “severe” and “hazardous” levels, prompting urgent calls for action.
Notably, Delhi, long considered the epicenter of india’s pollution woes, has slipped to 13th place in the rankings. This shift, though, does not signify improvement, but rather a widening of the problem, as smaller cities such as Sri Ganganagar, Siwani, and Abohar now bear the brunt of the most toxic air. According to the World Health Organization, exposure to such high levels of pollution can led to serious respiratory and cardiovascular diseases.
Top 10 Most Polluted Cities in the World (November 2,2025)

| 8 | Nangli Bahrampur | Uttar Pradesh | 438 |
| 9 | Bhiwani | Haryana | 437 |
| 10 | Sasroli | Haryana | 433 |
Despite ranking lower on the global list,Delhi’s air quality remains critically poor,with an AQI of approximately 412.Residents are experiencing reduced visibility and facing serious health risks. Officials attribute the current conditions to a combination of factors including crop residue burning in neighboring states, vehicle emissions, industrial output and construction activities.
Causes of the Intensifying pollution
Several interconnected factors contribute to the deteriorating air quality in India. The seasonal shift towards cooler temperatures and weaker winds during late October and November traps pollutants near the ground. this is further exacerbated by widespread agricultural practice of stubble burning in states like Punjab and Haryana. Dust from construction sites and unpaved roads also contribute significantly, alongside emissions from older vehicles and industrial facilities.
Did You Know? According to a 2023 study by the Center for Science and Surroundings, vehicular emissions account for approximately 40% of PM2.5 pollution in Delhi during winter months.
Understanding Air Quality and it’s Impact
Air pollution, notably particulate matter (PM2.5 and PM10), poses a considerable threat to public health. Prolonged exposure can lead to respiratory illnesses, cardiovascular problems, and even cancer. Children, the elderly, and individuals with pre-existing conditions are particularly vulnerable. Addressing this crisis requires a multi-faceted approach involving stricter emission controls, promotion of cleaner energy sources, and sustainable agricultural practices.
Pro Tip: Regularly check local air quality indices and limit outdoor activities during periods of high pollution. Consider using air purifiers indoors and wearing masks when venturing outside.

Top 10 Most Polluted cities Worldwide: Delhi Elevates as North India Faces Toxic Smog Crisis
Delhi’s Air Quality: A Deep Dive into the Crisis
As of November 2nd, 2025, Delhi, india, is experiencing a severe air quality crisis, consistently ranking among the most polluted cities globally. This isn’t a new phenomenon, but the intensity of the current smog episode is especially alarming.The air Quality Index (AQI) frequently exceeds 400, categorized as “hazardous,” posing notable health risks to millions. Key pollutants driving this crisis include PM2.5, PM10, nitrogen dioxide (NO2), and ozone (O3).
* PM2.5: These fine particulate matter particles, 2.5 micrometers in diameter or less,are especially hazardous as they can penetrate deep into the lungs and bloodstream.
* PM10: Coarser particles, still harmful, contributing to respiratory issues.
* NO2: Primarily from vehicle emissions and industrial activity, irritates the airways.
* O3: Ground-level ozone, a secondary pollutant formed by chemical reactions in sunlight, exacerbates respiratory problems.
The primary contributors to Delhi’s pollution include vehicle emissions, industrial pollution, construction dust, crop burning in neighboring states (Haryana and Punjab), and meteorological factors like stagnant winds and temperature inversions. The current situation has led to school closures, advisories against outdoor activities, and a surge in respiratory illnesses.
