|---|---|---|---|---|---|
| primary air pollutants | types of unmodified materials that, when released into the environment in sufficient quantities, are considered hazardous
🗑
|
||||
| secondary air pollutants | pollutants produced by the interaction of primary air pollutants in the presence of an appropriate energy source
🗑
|
||||
| criteria air pollutants | those air pollutants for which specific air quality standards have been set by the U.S. Environmental Protection Agency
🗑
|
||||
| hazardous air pollutants (air toxins) | certain airborne compounds with high toxicity
🗑
|
||||
| cardon monoxide (CO) | a primary air pollutant produced when organic materials, such as gasoline, coal, wood, and trash, are incompletely burned
🗑
|
||||
| particular matter | minute solid particles and liquid droplets dispersed into the atmosphere
🗑
|
||||
| carcinogenic | the ability of a substance to cause cancer
🗑
|
||||
| sulfur dioxide (SO2) | a compound containing sulfur and oxygen produced when sulfur-containing fossil fuels are burned. When released into the atmosphere, it is a primary air pollutant
🗑
|
||||
| oxides of nitrogen | primary air pollutants consisting of a variety of different compounds containing nitrogen and oxygen (NO, N2O, and NO2)
🗑
|
||||
| nitrogen monoxide (NO) | a compound composed of one atom of nitrogen and one atom of oxygen; a primary air pollutant
🗑
|
||||
| nitrogen dioxide (NO2) | a compound composed of one atom of nitrogen and two atoms of oxygen; a secondary air pollutant
🗑
|
||||
| volatile organic compounds (VOCs) | airborne organic compounds; primary air pollutants
🗑
|
||||
| hydrocarbons (HC) | group of organic compounds consisting of carbon and hydrogen atoms that are evaporated from fuel supplies or are remnants of the fuel that did not burn completely and that act as a primary air pollutant
🗑
|
||||
| ozone (03) | a molecule consisting of three atoms of oxygen that absorbs much of the sun’s ultraviolet energy before it reaches the Earth’s surface
🗑
|
||||
| photochemical smog | a yellowish-brown haze that is the result of the interaction of hydrocarbons, oxides of nitrogen, and sunlight
🗑
|
||||
| thermal inversion | the condition in which warm air in a valley is sandwiched between two layers of cold air and acts like a lid on the valley
🗑
|
||||
| acid deposition | the accumulation of potential acid-forming particles on a surface
🗑
|
||||
| acid rain (acid precipitation) | the deposition of wet acidic solutions or dry acidic particles from air
🗑
|
||||
| greenhouse gas | gas in the atmosphere that allows sunlight to enter but retards the outward flow of heat from the Earth
🗑
|
||||
| greenhouse effect | the property of carbon dioxide (CO2) that allows light energy to pass through the atmosphere but prevents heat from leaving; similar to the action of glass in a greenhouse
🗑
|
||||
| carbon dioxide (CO2) | a normal component of the Earth’s atmosphere that in elevated concentrations may interfere with the Earth’s heat burned
🗑
|
||||
| methane (CH4) | an organic compound produced by living organisms that is a greenhouse gas
🗑
|
||||
| nitrous oxide | N20, one of the oxides of nitrogen
🗑
|
||||
| radon | radioactive gas emitted from certain kinds of rock; can accumulate in very tightly sealed buildings
🗑
|
||||
| decibels | a unit used to measure the loudness of sound
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
