Database: outdoor air pollution in cities (World Health Organization – Public Health and Environment)
The focus today is on a list of cities in the world with the most and least pollution. Not surprisingly, those with the least pollution are small cities located some distance from industry in western Canada and USA and in southeast Australia, while the most polluted are in developing industrialized countries in Asia and Central America. The measure used for this comparison is particulate matter which comes from a number of sources in industry and from (diesel) vehicle emissions. IMHO, a better measure in cities afflicted with traffic air pollution might be nitrogen and carbon oxides (NO2 and CO2).
