EPA Victoria monitors the air for two categories of particle size : PM 2. What is Particulate Matter? Particulate matter (PM) is a term used to describe the mixture of solid particles and liquid droplets in the air. It can be either human-made or naturally occurring.

Some examples include dust, ash and sea-spray. Hence it is important to investigate the impact of PM2. China combat the current air pollution problems. Some particles are released directly from a specific source, while others form in complicated chemical reactions in the atmosphere.
