sourcesink One can come up with a pretty large list of air pollution sources, especially for the anthropogenic ones. Note that the same processes and activities can occur on both the natural and anthropogenic lists. On the anthropogenic side, this means that humans are doing things that are enhancing the "natural" emission of air pollutants. For example, commerical agriculture could increase the emissions of gases associated with organic waste decay and the production of dusts from plowed, dry fields.

Air pollution sinks are the opposite of sources.
fundsource Transport of pollutants involves air movement, or wind.

Resuspension is the opposite of deposition. The solid object (the ground, a wall, etc.) that can or will hold the pollutant gas molecules or aerosol particles does not need to be stationary--particles could collide and stick to a moving vehicle (deposition occurs) or be dislodged from the surface of the vehicle as air rushes past the moving vehicle (resuspension occurs).
fundsink Dispersion can involve air movement, such as the wind. This would be the opposite of the source process transport. Chemical reactions can use up a pollutant (and thus be a sink of that pollutant) and produce another pollutant (and thus be a source of that other pollutant).
