PM2.5 refers to particles that have diameter less than 2.5 micrometres (more than 100 times thinner than a human hair) and remain suspended for longer. These particles are formed as a result of burning fuel and chemical reactions that take place in the atmosphere. Natural processes such as forest fires also contribute to PM2.5 in the air.

Primary PM2.5: PM2.5 that is formed directly from a combustion source, or is otherwise emitted as PM2.5 without having to react with other chemicals, and is not formed from the cooling of hot gases. Re-entrained dust: Dust kicked up from a roadway surface – considered one of the sources of particulate matter and PM2.5.

PM2.5 refers to atmospheric particulate matter (PM) that have a diameter of less than 2.5 micrometers, which is about 3% the diameter of a human hair. Commonly written as PM 2.5, particles in this category are so small that they can only be seen with a microscope. PPM/2 Is a Garry's mod addon that allows you to play as customizable pony!
