Outdoor Airpollutants
Air quality index
Stratospheric O3
Acid Deposition/Misc.
Miscillaneous
100
The source of this pollutant is usually combustion of fuels and often is an respiratory irritant and coverts to sulfuric acid in the atmosphere which is harmful to plants and aquatic life.
What is Sulfur Dioxide (SO2)?
100
The color and AQI range for good air quality conditions.
What is green; 0-50?
100
Chemical formula for CFC?
What is CFCl3?
100
The average pH of rainwater.
What is 5.5-6?
100
A realitvely warm layer of air at mid-altitude covers a layer of cold, dense air below. This traps pollutants close to the ground.
What is thermal inversion?
200
This air pollutant is usually derived from incomplete combustion, car exhaust, and poor ventilation from fires and bonds to hemoglobin thereby interferring with the oxgen exchange process.
What is CO?
200
Sensitive group.
Who are infants, elderly, and people with respiratory issues?
200
What type of radiation does the ozone layer block from reaching the troposphere?
What is UV-B and UV-C?
200
Three effects of acid deposition.
What is lowering pH of aquatic systems, metals mobilization, erode buildings?
200
The precursors to tropospheric ozone.
What is sunlight, VOCs, water, oxygen, and nitrogen oxides?
300
This pollutant is derived from soil, soot, or dust and can increase respiratory and cardiovascular diesease as well as reduce visbility.
What is Particulate Matter (PM)?
300
The formula for calculating AQI.
What is amount of pollutant in the air/ standard amount X 100?
300
The main contributor that breaks down stratospheric ozone.
What are chloroflurocarbons (CFCs)?
300
Montreal Protocol
What is the meeting of nations in 1986 to discuss ways to reduce the amount of CFCs and other ozone depleting agents in the air by 50% by 2000. This was the most far-reaching enviromental treaty to date. Because of this Cl concentrations have stabalized in the stratosphere.
300
Sick building syndrome
What is a phenomenon caused by when new construction causes a buildup of toxic compounds and pollutants in an airtight space?
400
This air pollutant is a secondary pollutant formed by the combination of sun, water, oxygen, VOC, and NOx and exacerbares respiratory ilnesses.
What is ozone (O3)?
400
Calculate the AQI for the following Houston, TX data Carbon monoxide: 12 ppm standard: 9ppm Ozone: .07ppm standard: .08ppm Nitrogen Oxides: .01 ppm standard: .053ppm
What is AQI of 80?
400
The place and time of year where the depeltion of ozone is most significant.
What is Aug-Nov. in Antarctica?
400
This indoor air pollutant is often used for insulation and can have drastic health impacts such as mesothelioma.
What is asbestos?
400
Location of the ozone layer.
What is the stratosphere?
500
The source of this pollutants is usually cleaning supplies, evaporation of fuels and is a precursor to ozone.
What are VOCs (volatile organic compounds)?
500
Calculate the AQI for the following data: PM 2.5- 35 standard-65 Ozone- .15 standard- .08 nitrogen dioxide- .04 standard- .053
What is an AQI value of 106?
500
The process in which CFCs breakdown stratospheric ozone.
What is CFCs come from cooling agents, spray cans, or styrofoam and make their way to the stratosphere. Once in the stratospher, a Cl molecule from the CFCs removes and oxygen molecule from O3; leaving ClO (chlorine monoxide) and O2 (oxygen)?
500
This indoor air pollutant often comes from rocks and soil beneath the house and can cause a varities of cancers.
What is radon gas?
500
Five main layers of the atmosphere in order from earth up.
What is troposphere, stratosphere, mesosphere, thermosphere, exosphere?
