Particulate Matter can be organic and inorganic in nature. Some of these particles are:

  • Dust
  • Pollen
  • Soot
  • Smoke
  • Mineral Dust

The following are the two methods on how these particulate matter can enter the atmosphere:

  • Direct - Like when fuel is burnt and when dust is carried by wind, or
  • Indirect - Like when gaseous pollutants previously emitted to air turn into particulate matter

Some common direct and indirect sources include:

  • Emissions from Motor vehicles
  • Wood burning stoves and fireplaces
  • Dust from construction, landfills, and agriculture
  • Wildfires
  • Brush/waste burning
  • Industrial Emissions
  • Windblown dust from open lands
