Air pollution can be created from many different types of sources. These sources are often grouped into two main categories: mobile sources and stationary sources.

Mobile Sources: Mobile sources are vehicles and moveable engines that create air pollution. This includes most forms of transportation. Cars, trucks, lawn mowers, construction equipment, airplanes, and trains are examples of mobile sources.

Stationary Sources: Stationary sources are sources of air pollution that do not move, including power plants, factories, and industrial facilities. Stationary sources also include smaller sources of air pollution such as gas stations and dry cleaners.
