PM10: The coarse particles are between 2.5 and 10 micrometers (from about 25 to 100 times thinner than a human hair). These particles are called PM10 (we say "P M ten", which stands for Particulate Matter up to 10 micrometers in size). These particles cause less severe health effects mostly in the upper respiratory tract. PM 10: “Inhalable coarse particles” are between 2.5 and 10 micrometers in diameter PM 2.5 : “Fine particles” are smaller than 2.5 micrometers in diameter For a size comparison, a single strand of human hair on average is 70 micrometers in diameter, making it 30 times larger than the largest fine particle.
Particle emissions of road traffic are generally associated with exhaust emissions. Until recently particle emissions due to abrasion processes were neglected. However, the research project ASTRA2000/415 showed clearly the important contribution of these emissions to the PM10 load of the ambient air. concentration of particles with a diameter of less than 10 µm (PM10) and of particles with a diameter of less than 2.5 µm (PM2.5). PM2.5, often called fine PM, also comprises ultrafine particles having a diameter of less than 0.1 µm. In most locations in Europe, PM 2.5 constitutes 50–70% of PM10.

Specific such as particles, was needed for comparison but not in central focus. Effekten av den minskade användningen av dubbdäck för PM10-halterna på Effect on particle generation and concentrations of PM10 of reduced studded tire av M Gustafsson · Citerat av 7 — suspension of particles from the road surface, they might be cleaned away or bound to the surface using dust-binders. Resulting problems concerning PM10 are The source origins of these dust outbreaks were traced back to North Africa, the Arabian Peninsula, and the Levant. The 24-hour PM10 concentrations during These limits are for particles of the size PM10 (diameter less than 10. µm) and for PM2 the particle concentrations in relation to environmental quality standard.

Non-Exhaust PM10 and Road Dust Book, 2018 [WorldCat.org]
By way of comparison, a human hair is about 100 micrometres, so roughly 40 fine particles could be placed on its width. PM 10 and PM 2.5 are not used for any application. When someone talks about PM 10 they are referring to particles smaller than 10 µm. These particles include dust, pollen and mold spores. Conversely, when someone references PM 2.5 they are referring to particles smaller than 2.5 µm. These smaller particles include combustion particles, organic compounds and metals. The abbreviation PM stands for particulate matter, and the number to the right indicates the particle size.
