Answer the following questions in your own words: (On separate piece of paper)
1: How can ozone be both good and bad?
It can be good as it deflects UV rays away from the earth. It can be bad as it can harm the crops and vegetation when it reaches the troposphere.
2: What is happening to the “good” ozone layer?
Artificial man-made chemicals are being released damaging it.
3: How much damage can 1 Chlorine atom do? Explain.
It has the ability to terminate 100 thousand ozone molecules.
4: How does the “good” ozone protect the Earth?
The good ozone protects the earth from the sun's UV rays.
5: What is being done about ozone depletion?
The Montreal Protocol was established between 181 countries lowering the production of substances that lower the ozone.

1: What causes “bad” ozone?
The contact of sunlight on nitrogen oxides and volatile organic compounds.
2: What are some sources of bad ozone?
Cars, industrialization, solvents.
3: How does “bad” ozone affect human health and environment?
The inhalation of ozone is able to cause:
4: What is being done about “bad” ozone?
The clean air act was established.
5: What can we do/actions can we take to reduce our risks?
Carpooling and reducing our use of appliances.
Ozone- Air Now
Go to: www.epa.gov/airnow/
In the far right corner- choose “Ozone”- found under Air Quality Basics. Read about
good and bad ozone and answer the following questions.
1: Where is the good ozone located and what is its function?
It is located about 6-30 miles about earth's surface and it protects the earth from UV radiation
2: What depletes good ozone?
Chemicals made from man.
3: Where is the bad ozone located and what creates it? What does NOX and VOC stand
for?
Bad ozone is located at the troposphere. It is created through the emissions of industry and vehicles.
Nox= Nitrogen Oxides
Voc= Volatile Organic Compounds.
4: List three health problems associated with bad ozone. (Hint: You may need to go to
Ozone and your Health- How can ground-level ozone affect your health?)
5: Scroll down to the Air Quality Index Color Chart- Write down a one-word descriptor
of each color code.
Green-Good
Yellow-Moderate
Orange-Unhealthy (sensitive)
Red-Unhealthy
Purple-Very Unhealthy
6: After answering this question, go back to Air Now at: www.epa.gov/airnow/
In the far left corner, choose National Overview and then choose Ozone Now.
What is the current ozone reading for our area? 180 (use color code)
How Ozone is Formed- Notes
-Ozone (O3) is created from Nitrogen Oxides (NOx) and Volatile Organic Compounds (VOCs)
-These chemicals come from vehicles and factories
-When NOx and VOCs mix with sunlight, ozone is formed
Good up High, Bad down Low- Notes
-In the upper atmosphere the ozone protects Earth
-Ground level ozone can be bad for human health and the environment
-Ground level ozone created from human pollutants
-Coughing, chest pain, throat irritation, and congestion can occur from breathing ozone
-Ground level ozone damages crops, trees and other vegetation and is a main ingredient of urban smog
-Ozone layer blocks some of the sun's harmful UV rays
-Ozone is produced naturally in the stratosphere
-Human mad chemicals are depleting the ozone layer, and some of those chemicals such as CFCs stay in the stratosphere for many years
-Ozone depletion can lead to increased UV radiation, which can cause skin cancer, cataracts, and it also damages crops

Smog City 2
Take notes about what the various condition changes do to the AQI.
-As the city conditions worsened, the AQI rose.
-Lowering the pollution would make the living conditions in the city healthier and the AQI would lower
Which set of conditions produce the best possible scenario for the city?
-Low inversion, warm temperature, low wind, low energy sources, low amount of cars and trucks, low amount of off road, low amount of consumer products used, low amount of industry, and a low population.
Which set of conditions produce the worst scenario for the people, animals and plants of Smog City?
-Cloudy skies, low temperature, lots of vehicles, many consumer products used, high population, high industry, high inversion, high energy sources, high off road.
Summary: On your paper, write a 2-3 paragraph summary about what you have learned about ozone, ozone depletion, ozone destruction and air quality by completing this assignment. Make sure to use the new vocabulary that you have learned.
-Ozone can be both good and bad for us. There is both good and bad ozone. The good ozone is located high up in the atmosphere (in the stratosphere) and it helps protect the Earth from the sun's harmful UV rays. The bad ozone is located lower, and it is life threatening. The bad ozone is composed up of Volatile Organic Compounds (VOCs) and Nitrogen Oxides (NOx), and when inhaled it can create a number of human health effects such as lung cancer, coughing, chest pain and throat irritation. Bad ozone lowers the air quality and makes it unhealthy for us to inhale. The good ozone is being depleted due to human made chemicals, and some of them such as CFCs remain in the atmosphere for a long time. The depletion of the ozone layer can also have some devestating health effects. Since there is nothing to block the incoming UV rays, the increase in UV exposure can lead to damaged crops, skin cancer, and cataracts.
-There have been some solutions to reducing the bad ozone and restoring the good ozone. Little things that we do such as carpooling have more effects than we realize. Since vehicles contribute to the amount of smog and bad ozone, carpooling can significantly reduce those emissions. 181 countries made a treaty called the Montreal Protocol in 1987, which allowed them to phase out the production and use of ozone-depleting substances, and to help keep our air quality healthy the EPA has set protective health-based standards for ozone in the air we breathe under the Clean Air Act.
