Air pollution is one of the major environmental health risks and has caused millions of premature deaths. The main pollutant quantified in this report is PM2.5 particulate matter, which is extremely small particles with a diameter of less than 2.5 micrometers. These particles can penetrate deep into the lungs and even enter the bloodstream, causing a variety of health problems such as respiratory diseases, cardiovascular diseases, and many other serious diseases. Methodology: This ranking is based on air quality measurements from numerous monitoring stations around the world. The annual average concentration of PM2.5 is usually expressed in micrograms per cubic meter (µg/m³). This ranking is determined based on the PM2.5 levels of the cities; the higher the number, the worse the air quality.
