Ett annat partikelmått som mäts är PM2,5 som är partiklar som är mindre än 2,5 mikrometer (μm). Dessa något mindre partiklar har en tydlig

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.

As particles pass through Cautionary Statement (for PM2.5) 0 - 50: Good: Air quality is considered satisfactory, and air pollution poses little or no risk: None: 51 -100: Moderate: Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. For each country, reductions in five different pollutants have been calculated separately: with an emission reduction of 15% for SOx, NOx, NH3, NMVOC and PPM10 (as a sum of PPM2.5 and PPMcoarse) respectively. The deposition tables show the contribution from one country to another. A 2002 study indicated that PM 2.5 leads to high plaque deposits in arteries, causing vascular inflammation and atherosclerosis – a hardening of the arteries that reduces elasticity, which can lead to heart attacks and other cardiovascular problems. 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!
