Extract of sample
Some of these particles are often directly released into the atmosphere while others are formed when they are mixed and react with other pollutants in the atmosphere. These particles often come in various sizes. Fine Particles (PM2.5). These are also known as fine particles and usually measure up to 2.5 microns in diameter. These are seen in almost all sources of fuel combustion, from automobiles, wood burning, industrial plants, and power plants. With their diminutive configurations, they are likely to deeply penetrate the lungs and respiratory system. Where large concentrations of this fine particulate matter are formed, a haze is usually apparent. Coarse Particles (PM10). These are particles which measure about 2.5 to 10 microns and are derived from various sources like natural wind, erosion of soil, or airborne residue from industrial plants. These particles are often visible to the naked eye, and can appear collectively as haze, dust, or soot.
