Answer:
Suspended particulate matter (SPM) are finely divided solids or liquids that may be dispersed through the air from combustion processes, industrial activities or natural sources.

Explanation:
The particle size is a very important characteristic of particulate matter and determines the reduction techniques that may be used. Large-sized particles can be removed by techniques based on mechanical principles (cyclones, gravity collectors, etc.) but only electro-filters or fabric filters are capable of removing finer particles.
The chemical composition of particles can affect the efficiency of some reduction techniques. For example, the efficiency of an electro-filter depends on the resistivity of the particles, which in turn depends on their chemistry.
