Name:
Atmospheric Systems – Reducing Contaminants
1
/30
Indicator:
- examine scientific principles of technologies such as air scrubbers, baghouse filters,
electrostatic precipitators, and catalytic converters that have been developed to reduce
contaminants in motor vehicle and industrial emissions
- investigate processes designed to manage and improve indoor air quality in residential,
commercial, and industrial buildings and structures in order to minimize damage to human
health.
- Develop a generalization about the relationship between human population density and
air quality
Objective:
In this assignment your goal is to do some research on ways that humanity is mitigating
their impact on our air quality. You will look into some technologies dealing with improving
outdoor air quality by reducing a) motor vehicle and industrial emissions and b) processes
designed to improve indoor air quality. You may create your own format to type out this
information, but I would recommend finding this assignment on the wiki and using the
questions in their current order.
a) Motor Vehicles and Industrial Emissions (select one of the below to answer)
Air Scrubber
Baghouse Filter
Electrostatic Precipitator
Catalytic Converter
Other? ________________
Then answer the following:
What is it (1)?
What is it used with or in (1)?
When was it developed and by who (2)?
What contaminant does it reduce (and what would this contaminants normally
cause) (2)?
How does it reduce the contaminants? Include a picture (2)
List references where you got your information from (1)
You will present this information to the class (1) -

Name:
b) Ways to Reduce Indoor Emissions (select one of the below to answer)
tip: Search “how to reduce ________ (contaminant – ex. mold) indoors.”
Residential – search “common household airborne contaminants” then ways to
mitigate them
Commercial – search “common workplace airborne contaminants” then ways to
mitigate them
Industrial – search “common industrial airborne contaminants” then ways to
mitigate them
Then answer the following:
What is the reducing technology and in what building is it present in (residential,
commercial, etc) (1)?
What is it used with or in – ie. What normal emission in the house will it ‘fix’ (1)?
When was it developed and by who (2)?
What contaminant does it reduce (and what would this contaminants normally
cause) (2)?
How does it reduce the contaminants? Include a picture (2)
List references where you got your information from (1)
You will present this information to the class (1) -

Part 2 – Long Answer
Referencing the pictures below, what is a generalization we could make about human
population density and air quality – as well as the human population in reference to
greenhouse gases? In what places is your generalization accurate and is there any in which it is
inaccurate (5 solid points answering the questions – 10 marks)?
Figure 1 - Human Population Density Worldwide (Darker = more people)
Figure 2 - Air Pollution Worldwide by concentration of pollutant
particles in the air.
