10New Delhi, India
New Delhi consistently ranks as one of the most polluted cities in the world, particularly in terms of air quality. The combination of industrial emissions, vehicle exhaust, and agricultural burning in surrounding areas creates a toxic smog that blankets the city, especially during the winter months. The Air Quality Index (AQI) regularly exceeds hazardous levels, with airborne particles (PM2.5 and PM10) posing significant health risks. In addition to air pollution, New Delhi struggles with inadequate waste management and open dumping, leading to widespread litter and uncollected garbage in many parts of the city.
