Definition - What does Particulate Material mean?

Particulate material or particulate matter (PM) refers to very small liquid or solid particles which are pollutants or cause air pollution. Particulate material varies greatly in terms of size, shape, electrical charge and other factors or qualities, as well has how dangerous they are to human or environmental health and safety.

Safeopedia explains Particulate Material

The size of the particles in particulate material is directly proportionate to how much they are a hazard to human health. The environmental protection agency (EPA) is primarily concerned by particles that are ten micrometers or less in diameter. This is because these particles are likely to be inhaled into the lungs and cause serious health problems. Particulate matter is grouped into both coarse fibres which can be inhaled, and fine particles.
