Particulate Matter or PM
Very small but solid pieces of air pollution that have been found to penetrate deeply into human lungs. Particulate matter can also be called particle emissions.
particulate matter (in atmospheric chemistry)
General term used to describe airborne solid or liquid particles of all sizes.
Note: The term aerosol is recommended to describe airborne particulate matter.
Particulate matter Any finely-divided airborne solid or liquid material with a diameter smaller than 100 micrometers while it is in the air.
Particulate Matter (PM) or Particle Pollution. Small particles of matter such as dust and soot that are suspended in the air. PM is emitted from sources such as motor vehicles, some industrial processes and forest fires.
Particulate Matter: A state of matter in which solid or liquid substances exist in the form of aggregated molecules or particles. Airborne particulate matter is typically in the size range of 0.01 to 100 micrometers.

Particulate Matter (PM): Any material, except pure water, that exists in the solid or liquid state in the atmosphere. The size of particulate matter can vary from coarse, wind-blown dust particles to fine particle combustion products.
(Particulate Matter) PM2.5 - Aerosol particles that are smaller than or equal to 2.5 micrometers or have an aerodynamic diameter of 2.5 micrometers. In the Clean Air Act Revision of 1997 modified particulate standard to include PM2.5.

Definition (english only)
A collective name for fine solid or liquid particles added to the atmosphere by processes at the earth's surface. Particulate matter includes dust, smoke, soot, pollen and soil particles.

In extreme cases, they eject vast quantities of gases such as sulphur and nitrogen oxides and particulate matter, usually soot and mineral ash, high into the troposphere.
Airborne Particulates - Total suspended particulate matter found in the atmosphere as solid particles or liquid droplets. Chemical composition of particulates varies widely, depending on location and time of year.
