causes and control
ozone
indoor
100
This stationary source generates pollutants from open areas exposed to wind.
What is fugitive source
100
This chemical os a colorless odorless gas that primarily comes from burning fossil fuels(coal plants)and is an important precursor to acid rain
What is sulfur dioxide
100
One way to control the effects of this is to add lime to lakes and ponds.
What is acid rain
100
What makes ozone in the stratosphere
What is UVc and O2
100
photocopiers, computers and other electrical devices can make this indoor air pollutant
What is ozone
200
automobiles, aircraft, boats and trains produce this source of pollution
What is mobile
200
This is a yellowish brownish gas and is a major contributor to smog and acid rain. It comes mostly from automobiles and power plants that burn fossil fuels
What is nitrogen oxides
200
Photochemical smog is caused primarily by this
What is automobile use
200
Ozone blocks this from reaching the Earth
What is UVb
200
This is naturally occurring radioactive gas found in certain soils can become concentrated indoors. It can lead to cancer
What is radon
300
These pollutants are emitted directly into the air
What is primary
300
A colorless odorless gas that attaches to hemoglobin and kills in small concentrations. It forms from the incomplete combustion of fuels. 90% actually comes from natural sources.
What is carbon monoxide
300
This occurs when warm air is trapped under cooler air and leads to decreases in air quality
What is temperature inversion
300
These man made chemicals deplete the stratospheric ozone
What is CFCs
300
Many building materials such as furniture, carpeting etc. outgas this indoor pollutant
What is formaldehyde
400
Ozone is this type of pollutant because it is produced by a primary pollutant that reacts with atmospheric compounds
What is secondary
400
This heavy metal is an important constituent of car batteries, and used to be in gasoline. It can lead to decreases in IQ, is toxic to wildlife and can cause behavioral problems, ardiovascular and kidney disease.
What is nitrogen oxides and sulfer dioxide
400
The potential for air pollution in urban areas is determined by (list at least 2)
What is rate if emissions distance air mass moves downwind through a city average speed of wind elevation to which pollutants can be thoroughly mixed(lower worse)
400
These cause a polar vortex to help decrease the amount of stratospheric ozone in the Antarctic zone
What is polar stratospheric clouds
400
This occurs when a building where people's symptoms may or may not be linked to air quality.
What is sick building syndrome
500
Smog is this
What is smoke and fog
500
Variable mixtures of tiny particles suspended in the air are called this
What is particulates
500
How can sulfur be removed at power plants
What is scrubbing
500
What element do CFCs generate that destroys ozone in the stratosphere
What is Cl
500
This ailment is caused by exposure to air with high concentrations of soot or carbon rich dust
What is black lung disease
