Unit 7 Vocabulary ( Atmospheric Pollution )

A colorless, odorless gas made up of one carbon atom and two oxygen atoms.

A colorless, toxic gas with a bitter choking order due to the gas being composed of one sulfur atom and two oxygen atoms.

Mixture of microscopic particles and droplets suspended in the air such as dust, soot, smoke, pollen and liquid droplets.

A type of air pollutant that forms when sunlight triggers chemical reactions between certain pollutants in the atmosphere such as nitrogen oxides and volatile organic compounds

Ozone (O3) that exists in the troposphere which is the lowest layers in the earth’s atmosphere. A pollutant and a major component of smog.

The deposition of acid components such as sulfuric acid and nitric acid from the atmosphere to the earth’s surface.

Rain, snow, fog or any other form of precipitation with a pH lower than normal.

Set legislation of strict air quality standards; tracking national emission and ambient conditions (temperature, humidity, pressure, light noise and vibration.)

Substances that enter the air directly from natural or human sources

Harmful substances that form in the atmosphere through chemical reactions involving primary pollutants and other atmospheric components

Organic compounds that easily evaporate into the air and react with nitrogen oxides in sunlight to form air pollutants

A reversal of the normal behavior of temperature in the troposphere.

The emission of air pollutants generated by natural processes rather than human made processes. -Carbon Dioxide -Methane (CH4) -Nitrous Oxide (N20) -Ozone (03)

A colorless and odorless gas or liquid that is composed of one carbon and two oxygen’s

A naturally occurring minerals made of very thin strong fibers - mainly used in construction

A type of fungus that grow on wet, damp and warm environment

Dry powder composed of tiny particles of earth or waste matter lying on the ground or on surfaces or carried in air

A type of carbonate sedimentary rock which is the main source of lime

Sounds at high levels enough to cause physiological stress and hearing loss

A colorless gas made up of 3 oxygen’s that is a natural part of the environment. Sits on the stratosphere.

An organic compound with the chemical formula being CH20

A type of device that is connected to gasoline pumps. -helps prevent fumes from escaping into the atmosphere when fueling (hydrocarbons, benzene and ozone)

A type of scrubbing system that uses a liquid substance to remove harmful materials from industrial exhaust gasses. A combination of water and air to actually separate a remove particles.

An exhaust emission control device which converts toxic gasses and pollutants in exhaust gas from an internal combustion engine into less toxic pollutants.
