What is PM10 and PM2.5? Besides gaseous pollutants, the atmosphere can also be polluted by particles. These particles (either in suspension, fluid or in solid state), have a divergent composition and size and are sometimes called aerosols. They are often catalogued as 'floating dust', but are best known as particulate matter (PM).

TRANSPORT AS A MEANS FOR SUSTAINABLE URBAN Note: *Estimated average exposure to air pollution (PM2.5) based on imagery data 

Re-entrained dust: Dust kicked up from a roadway surface – considered one of the sources of particulate matter and PM2.5. The PM2.5 concentration levels can be volatile and tend to fluctuate over the day especially during periods of transboundary haze. Short-term fluctuations are greatly influenced by weather conditions.
