Outdoor Air Pollution
This layer of the atmosphere contains the GOOD ozone.
What is the Stratosphere?
This layer of the atmosphere contains BAD ozone.
What is the troposphere?
Low water pH is an effect of this type of deposition.
What is acid deposition?
Catalytic converters reduce which of the following pairs of pollutants in car exhaust?
you must name one to be correct.
What is CO and hydrocarbons?
Composed of fibers known to cause lung disease.
What is asbestos?
This pollutant is known to cause human neurological damage.
What is lead?
These two factors increase smog formation rates
What are sunlight and temperature?
Acid deposition is the result of these two air pollutants found in the atmosphere.
What are SO2 and NOx?
After SO2 is produced, what reduction method do coal-burning power plants use to prevent emissions from entering the atmosphere?
What are wet/dry scrubbers?
This indoor pollutant may enter a building through the basement, via radioactive decay underground.
What is radon?
This is a emission but not considered a pollutant.
What is CO2?
These compounds combine with NO to form photochemical oxidants
What are VOCs?
This action would be most effective in reducing acid rain.
hint: think generally
What is reducing fossil fuel usage?
Crushed limestone is mixed with coal before burning to reduce this type of pollutant.
What is SO2?
Has a stronger affinity for hemoglobin than oxygen has.
What is carbon monoxide (CO)?
Thermal inversion refers to.....
A warmer inversion layer of air trapping a cold air layer underneath it, trapping the pollutants with it.
Ozone formation peaks during this time of day
What is the afternoon?
It is outside of their range of tolerance/
This human health impact is most closely associated with atmospheric particulates.
What is a respiratory irritant?
ex: asthma, lung disease, lung cancer
Developing countries typically use this type of fuel for cooking and heating their homes.
What is biomass fuel? What is subsistence fuel?
Name the 6 criteria air pollutants covered by the Clean Air Act.
SO2, NOx, CO, PM, O3, Pb
When VOCs instead bind to the NO it is unavailable to react with the O3, resulting in higher ozone levels at night.
This water quality indicators should be measured to best determine if the wastewater is increasing the acidity of the river?
hint: not pH
What are hydrogen ions?
This method of reducing PM involves charged particles
What is an electrostatic precipitator?
This common VOC can be found in furniture and carpeting.
What is formaldehyde?
