(P 31,paragraph 2) Particulates Particulates , alternatively referred to as particulate matter (PM), atmospheric particulate matter, or fine particles, are tiny particles of solid or liquid suspended in a gas. In contrast, aerosol refers to bined particles and gas. Subtypes of atmospheric particle matter include suspended particulate matter (SPM), respirable suspended particle (RSP。 particles with diameter of 10 micrometres or less), fine particles (diameter of micrometres or less), ultrafine particles, and soot.
