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 alogued as ''floating dust'', but are best known as particulate matter (PM).
