Where Does Particulate Matter Come From?

A long-time leader in the energy sector, Levon Termendzhyan is an equity owner in Viscon USA and Viscon International. Through these companies, Levon Termendzhyan provides a diesel fuel additive known as Viscon that reduces particulate matter emissions in diesel fuel and boosts engine efficiency.

Particulate matter (PM) refers to a mix of liquid droplets and solid particles that affect both the environment and human health. Typically, PM is divided into two categories based on size, PM10 and PM2.5. 

Particles small enough to be inhaled, with a diameter of 10 micrometers and less, are classified as PM10. These particles are usually visible with the naked eye. PM2.5 particles, which are up to 2.5 micrometers in diameter, are not visible to the eye. 

Both sizes of particles may be caused by natural or man-made sources. Natural causes of PM include volcanoes, dust storms, and forest fires. Living vegetation that releases isoprene, spores, methanol, and other particles into the air are also responsible for creating particulate matter, as are tornadoes and sea spray.

Man-made causes of PM include coal, wood, and oil combustion. All of these common sources of power and heat in many countries around the world cause widespread particulates. Cement dust caused by construction or demolition, dust created by cars on the road, and tobacco smoke are also responsible for particulate matter in the air.
