Illness for 200
In Industrialized countries, one of the
biggest threats from air pollution is
from soot or fine particulates.
1. What size particulates?
2. Name 3 types of health risks which
are linked with air pollution.
Illness for 400
Persistent inflammation
of bronchi and small
airways in the lungs that
cause mucus buildup,
a painful cough and
involuntary muscle spasms.
Illness for 600
Condition where
airways become
permanently
constricted and
alveoli are damaged
Or destroyed.
Diseased
alveoli
Phenomena for 200
Occurs when a stable layer of warmer air
overlays cooler air, reversing the normal
temperature decline w/increasing height
and preventing convection currents from
dispersing pollutants. What is this
called?
Phenomena for 400
Name the chlorine-based aerosols
which are the principal agents of ozone
depletion in the stratospheric layer.
1. Name this pollutant?
2. What were they used in/for?
3. Why is this depletion an issue?

atmosphere include:
A. forest fires
B. Volcanoes
C. plant and animal decay releasing CO2
D. deforestation
E. All of the above
Legislation for 200
The discovery of the stratospheric
ozone depletion prompted this
international agreement to phase
out most uses of CFC’s by the year
2000. This is called the_________,
one of the most effective
international agreements ever.
Legislation for 400
“Dilution is the solution to pollution”
was one of the early approaches to
air pollution control. Give an
example and explain its rationale.
Legislation for 600
One of the most contested
aspects of the Clean Air Act is

million vehicles spew out more than
5500 tons of air pollution daily.
Which air pollutant is the
culprit and explain its effects
on the children in Mexico City.
Case Studies for 400
Seven of the worst cities with high
air pollution is in China. They
emit 10 million tons of soot and
15 million tons of sulfur dioxide
annually. How has this effected
their populations-name 2 ways.
Case Studies for 600
Norlisk, Russia (formerly a slave labor
camp in 1935) is the most polluted in the
world. Snow turns black as soon as it
falls—state the type of pollution present in
this Russian town.
There is hope…cities are making
progress in cleaning up our air
pollution. One prime example is
Cubatao, Brazil and was once
called the “valley of death”. How
did they clean up this city?
