Particulate matter or aerosol particles is the sum of all solid and liquid particles suspended in air and many of the particles are hazardous This complex mixture includes both organic and inorganic particles such as dust pollen soot smoke and liquid droplets These particles vary greatly in size composition and origin.
Suspended matter means all particulate material which is too small in size to have an appreciable falling velocity and which therefore persists in the atmosphere for lengthy periods Suspended particulate matter consists of smoke dust fumes and droplets of viscous liquids.
