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.

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.

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

  • PM2.5 (EPA):
    24-hour average: 35 µg/m³
    Annual average: 12 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.
