Particulate Matter (PM10, PM2.5, PM1)

This includes particles of diameter less than:

  • <10μ (PM 10)
  • <2.5μ (PM 2.5)
  • <1μ (PM 1)
Each of these types of particles are generated by different processes and have different adverse health effects on humans.

Particulate Matter, which refers to tiny solid or liquid particles suspended in the air that can be harmful to health.

Generated from where?


PM 10: Produced from construction, vehicular emissions, industrial processes, and natural sources like dust storms.

                                         
PM 2.5: Forms from combustion, industrial emissions, and atmospheric chemical reactions.                                                                     
PM 1: Generated from combustion, industrial processes, and fine smoke particles.

USEPA Guidelines

  • PM10 (EPA) 
    24-hour average: 150 µg/m³
    Annual average: 50 µg/m³  

  • PM2.5 (EPA):
    24-hour average: 35 µg/m³

Health effects

Short-term exposure:
Respiratory issues (coughing, wheezing) , Aggravates asthma, bronchitis, and heart disease.

Long-term exposure:
Increases risk of cardiovascular diseases, stroke, lung cancer, and premature death, PM2.5 and PM1 cause more severe health impacts due to their ability to penetrate deeper into the lungs.
