Some are emitted directly from a source, such as construction sites, unpaved roads, fields, smokestacks or fires. Most particles form in the atmosphere as a result of complex reactions of chemicals such as sulfur dioxide and nitrogen oxides, which are pollutants emitted from power plants, industries and automobiles.
How is particulate matter created?
"Particulate matter," also known as particle pollution or PM, is a complex mixture of extremely small particles and liquid droplets. ... These particles can be directly emitted from sources such as forest fires, or they can form when gases emitted from power plants, industries and automobiles react in the air.
What is the main source of particulate matter?
Primary sources cause particle pollution on their own. For example, wood stoves and forest fires are primary sources. Secondary sources let off gases that can form particles. Power plants and coal fires are examples of secondary sources.
