Particle Pollution (PM)

Particle pollution, also called particulate matter or PM, is a mixture of solids and liquid droplets floating in the air. Some particles are released directly from a specific source, while others form in complicated chemical reactions in the atmosphere.

Particles come in a wide range of sizes. Particles less than or equal to 10 micrometers in diameter are so small that they can get into the lungs, potentially causing serious health problems. Ten micrometers is less than the width of a single human hair.

  • Good
    Air quality is considered satisfactory, and air pollution poses little or no risk.
  • Moderate
    Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
  • Unhealthy for Sensitive Groups
    Members of sensitive groups may experience health effects. The general public is not likely to be affected.
