Understanding Air Quality

Particulate Matter PM 2.5

What is it?

Fine particles with a diameter smaller than 2.5 micrometers, 30 times smaller than a human hair.

Sources:

  • Vehicle combustion
  • Industrial plants
  • Wildfires
  • Wood stoves and cooking

Health Impact:

  • Penetrates deep into the lungs
  • Can enter the bloodstream
  • Causes respiratory and cardiovascular problems
  • Increases risk of asthma and chronic diseases

Reference Levels (μg/m³):

0-12 Good - Safe for everyone
12.1-35.4 Moderate - Sensitive groups take precautions
35.5-55.4 Unhealthy for sensitive groups
55.5-150.4 Unhealthy - Avoid outdoor activities
150.5-250.4 Very unhealthy
250.5+ Hazardous - Stay indoors

Particulate Matter PM 10

What is it?

Inhalable particles with a diameter smaller than 10 micrometers.

Sources:

  • Construction dust
  • Road dust
  • Agriculture
  • Industrial activities
  • Pollen and spores

Health Impact:

  • Respiratory tract irritation
  • Asthma aggravation
  • Coughing and difficulty breathing
  • Higher risk for children and elderly

Reference Levels (μg/m³):

0-54 Good
55-154 Moderate
155-254 Unhealthy for sensitive groups
255-354 Unhealthy
355-424 Very unhealthy
425+ Hazardous

Particulate Matter PM 1.0

What is it?

Ultrafine particles with a diameter smaller than 1 micrometer, the most dangerous for health.

Sources:

  • Diesel vehicle emissions
  • Combustion processes
  • Chemical industries
  • Atmospheric reactions

Health Impact:

  • Deeper lung penetration
  • Direct entry into the bloodstream
  • Affects the cardiovascular system
  • Linked to lung cancer
  • Nervous system damage

Important Note: PM1.0 is the most dangerous due to its ultrafine size which allows deeper penetration into the body.

Aerosol Optical Depth (AOD)

What is it?

A measurement of the amount of aerosols (suspended particles) in the entire atmospheric column.

How does it relate to PM?

AOD is a satellite indicator that correlates with ground-level particulate matter concentration.

AOD Value Interpretation:

0-0.1 Clean air
0.1-0.3 Moderate
0.3-0.5 Elevated
0.5-1.0 High
1.0+ Very high - Extreme smoke/dust conditions

Recommendations to Protect Your Health

Good Quality (Green)

  • Ideal for all outdoor activities
  • Perfect for exercise and sports
  • Safe for children, elderly, and sensitive individuals
  • No special precautions required

Moderate (Yellow)

  • Generally acceptable for most people
  • Very sensitive individuals: consider reducing intense activity
  • Monitor respiratory symptoms
  • Children with asthma: keep medication available

Unhealthy for Sensitive Groups (Orange)

  • Sensitive groups: limit prolonged outdoor activities
  • People with asthma/heart conditions: avoid intense exercise
  • Children and elderly: reduce time outdoors
  • General population can carry on with normal activities

Unhealthy (Red)

  • Everyone should limit outdoor activities
  • Avoid intense outdoor exercise
  • Wear N95 mask if you must go outside
  • Keep windows closed
  • Use indoor air purifiers

Very Unhealthy (Purple)

  • Avoid all outdoor activities
  • Stay indoors with windows closed
  • Wear N95/N99 masks if absolutely necessary to go outside
  • Sensitive groups: seek medical attention if symptoms appear
  • HEPA air purifiers recommended

Hazardous (Maroon)

  • HEALTH EMERGENCY: Everyone affected
  • Do NOT go outside under any circumstances
  • Seal doors and windows
  • Use air purifiers at maximum power
  • Follow health authority alerts
  • Prepare evacuation plan if necessary

About NitroAir
