Smog |
fog or haze combined with smoke and other atmospheric pollutants |
|
|
Troposphere |
|

|
|
|
Point Source |
locations where pollutants are emitted from a controllable site, such as the smokestack of a coal-burning power plant or the tailpipe of an automobile |
|
|
Non-point Source |
locations where pollutants are emitted from numerous, uncontrollable sites. |
|
|
Anthropogenic |
Inputs that come from a wide variety of human activities, including energy production, agriculture, and transportation. |
|
|
Primary Pollutants |
pollutants that are emitted directly to the atmosphere |
|
|
Secondary Pollutants |
compounds that form when primary pollutants interact with each other and other factors. |
|
|
Acidic Deposition |
The primary pollutants sulfur dioxide (from coal combustion) and nitrogen oxides (from coal combustion and vehicle exhaust) react with precipitation in the atmosphere to produce rain, snow, or fog that is significantly more acidic than "natural" precipitation |
|
|
Inversion Layer |
occurs when a “cap” of warmer air settles or forms on top of dense, cooler air. This prevents the upward movement of pollutants in the atmosphere. |
