Particulate Matter (PM2.5 and PM10)

Particulate Matter refers to very small particles of smoke, soot, dust, and even tiny droplets of liquid. PM2.5 refers specifically to fine particles that are smaller than 2.5 microns in diametre (a human hair is approximately 100 microns in diametre). PM10 refers to ‘coarse’ particulate, or material with a diametre less than 10 microns in diametre.

How is it Generated?

Anthropogenic Sources:  fuel combustion, fugitive dust generation (unpaved roads, agricultural fields), wood burning, residential heating, incineration, pesticide & herbicide applications and smoking. Natural Sources include: fugitive dust (open fields), pollen, bacteria, forest fires and sea salt spray.

What Are The Health Effects?

Provincial Guidelines:

What Can Be Done?

  1. Stay indoors during periods of known high ambient PM concentrations
  2. Reduce vehicle use and the use of less-efficient vehicles
  3. Apply dust suppressants to aid in the control of fugitive dust
  4. Use proper dust collection at source
  5. Use of modern farming practices
