Air Pollutants
This pollutant is a neurotoxicant, especially dangerous in children
What is lead?
This is necessary for NO2 in the atmosphere to be converted to NO + O, and then into smog.
What is sunlight?
This is the way that radon typically enters a home.
What is through cracks in the foundation?
This is the device on all gas cars that changes NOx, CO, and other hydrocarbons into CO2, N2, and H2O.
What is a catalytic converter?
Migration patterns, finding and mates, predator-prey interaction can be caused by this type of pollution.
What is noise?
The variable in an experiment that you control, such the amount of water given to plants to see how water affects the growth of a plant.
What is the independent variable?
This US Act allowed the EPA to regulate pollutants and (eventually) greenhouse gases.
What is the Clean Air Act?
This is the part of a plant that is damaged when exposed to tropospheric smog.
This indoor air pollutant can bind to hemoglobin and cause asphyxiation.
What is carbon monoxide?
This type of filter works like a vacuum bag and blocks PM from being released into the atmosphere.
What is a baghouse filter?
What is pH?
The variable in an experiment that is measured such as the growth of plants when given varying amounts of water.
What is the dependent variable?
This fossil fuel releases the most pollutants into the atmosphere.
What is coal?
This describes the temperature layers in a thermal inversion (starting from ground level).
What is dense, cool air, then less-dense warm air, then least dense coldest air?
This is the source of radon gas.
What are rocks containing uranium?
These are often used in coal power plants and use either dry chemicals or a wet mist to trap pollutants in power plants.
What are scrubbers?
These are the two primary pollutants that cause acid rain.
What are NOx and SO2?
When conducting an experiment to determine how the amount of water given to plants affects the growth, things such as amount of sunlight, type of plant, and amount of fertilizer must be kept constant. These are called this.
What are controls?
What is a primary air pollutant?
Cities that experience thermal inversions are usually located in this type of landform.
What is a valley/surrounded by mountains/located near a large body of water?
This is an example of an indoor particulate matter and its effect on human health.
What is smoke/mold/dust and it is a respiratory irritant or asbestos causes cancer?
Teacher discretion on this one!
What is a vapor recovery system?
This substance can reduce the effects of acid rain when found (or added to) soil.
What is limestone?
The following is an example of how to properly write this statement:
As the amount of water (IV) increases, the growth of the plant (DV) increases.
What is a hypothesis?
These standards were enacted in the 1970's to reduce VOCs and other pollutants from vehicles by regulating corporate average fuel economy.
What are CAFE standards?
Photochemical smog is not able to break down when this is present in the atmosphere.
What are VOCs?
This is the VOC in furniture, particle board, and carpet glue that gives it an odor and can be a respiratory irritant.
What is formaldehyde?
This device uses opposite charges to trap PM from escaping from a power plant or factory.
What is an electrostatic precipitator?
The presence or absence of this type of species can help a scientist determine the conditions of an ecosystem, such as the pH.
What is an indicator species?
The number of organisms tested in an experiment is called this.
What is the sample size?
