In a row, for the fourth consecutive year, Delhi topped as the most polluted city in the world. The world air quality report, as per the state of global air (SoGA) initiative, has declared which cities have the most exposure to bad air quality. The report published by SoGA provides information regarding polluted cities across the world.
They are available in the public domain to be viewed by practitioners, citizens, journalists, policymakers and scientists to take further steps to change the adverse effects of pollution.
The report also suggests that by 2050, 68 percent of the world’s population will be residing in cities and breathing urban air. Urbanisation grows faster in lower and middle-income countries, which results in adverse health conditions due to the rapid increase in emissions.
Urban cities have the maximum population due to growing job opportunities and better lifestyles. With the growing urbanization, urban cities are hubs for bad air quality. The polluted air affects the health of people. It risks life by creating diseases like heart problems, lung disease, type 2 diabetes, and respiratory-related infections. The impact of such diseases results in the early death of citizens.
As per the Air Quality Guidelines released by the World Health Organisation (WHO), healthy air quality should have an outdoor fine particle pollution concentration of 5 microgram per meter cube. But the guidelines defined by WHO don’t match the air quality of the major booming cities of the world.
As per the report, the data is taken from a survey of air pollution exposures and their health impacts. The data was collected from 7,000 cities within a time span of 2010 to 2019.
There are two categories of air pollutants found in the cities. One is the ambient fine particulate known as PM 2.5 and the other is the nitrogen dioxide (NO2). The latter one is a gaseous pollutant that gets released into the air through traffic-related air pollution.
Bakersfield is the most polluted city in the U.S. by year-round air quality, according to the ALA. It is the third city in California's Central Valley to make the list, joining the Fresno and Visalia areas. Bakersfield also ranks first for high-pollution days and third for most polluted cities by ozone exposure.

Chicago ranked second among major U.S. cities with the worst air pollution in 2023, its average annual concentration of dangerous fine particulate matter almost three times global guidelines, according to a recent report.
Which seven countries meet safe air quality levels? The seven countries that met the safe guideline of five micrograms per cubic metre of air (µg/m3) or less were Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand. Puerto Rico, Bermuda and French Polynesia also fell within safe levels.
The state of Hawaii boasts the cleanest average air in the entire U.S., at an AQI of 21.2. Even Hawaii's biggest city, Honolulu, ranks on the cleanest cities for lists for ozone, short-term particle pollution, and year-round particle pollution.
Cleanest air in the world in 2022. The cleanest air in the world is in Zurich. The pollution status is determined on the basis of average levels of PM2. 5 measured over a period of 12 months.
California is the most polluted state in the US. Six of the most polluted cities are located in California, with Fresno-Madera and Bakersfield being the two areas with the highest levels of particulate pollution. The worst ozone levels can be found in Los Angeles.
