Primary pollutants
... Several different processes remove particulates from the air. Gravitational settling, the process wherein they fall from the air, effectively removes larger particulates. Scavenging is the process in which falling precipitation collides with particulates and carries them to the surface. ...

... warmer air so that a layer of warm air is trapped between 2 layers of cool air. The bottom cool layer of air, which is denser than the warm layer of air above it, remains close to the surface. Any pollutants released in that layer of cooler air stay close to the Earth’s surface; this allows the prim ...
