What is PM10?
"Particulate matter," also known as particle pollution or PM, is a complex mixture of extremely small particles and liquid droplets. Particle pollution is made up of a number of components, including acids (such as nitrates and sulfates), organic chemicals, metals, and soil or dust particles. The size of particles is directly linked to their potential for causing health problems. EPA is concerned about particles that are 10 micrometers in diameter or smaller because those are the particles that generally pass through the throat and nose and enter the lungs. Once inhaled, these particles can affect the heart and lungs and cause serious health effects.
This work shows the relationship of the quantity of PM10 in the air with the proportion of urban population. The order of countries corresponds to their percentage of urban population (in ascending way), and the level of pollution (PM10) shapes the size and color of the circles.

- Countries analyzed: 151. Discarted those with population under one million to avoid adjacent effects.
