What is the most pulouted city?

Answer 1

As of my last knowledge update in October 2023, the title of the most polluted city often fluctuates, but cities like Delhi, India, and Lahore, Pakistan, frequently rank among the highest in terms of air pollution levels. Various factors contribute to this, including industrial emissions, vehicle exhaust, and construction dust. The Air Quality Index (AQI) is commonly used to measure pollution levels, and both cities have faced significant challenges in improving air quality. For the most current data, it's advisable to check recent reports from environmental agencies or organizations monitoring air quality.
