Appendix D

Air Pollution Chart

After reviewing Ch. 8 and 9 of your text, complete the following table, then respond to the

questions that follow:

Issue Sources Health/Environmental Effects

Carbon dioxide (CO

) Fire extinguishers,

photosynthesis,

carbonated drinks

Associated with global warming.

Chlorofluorocarbons

(CFCs)

Freon CFCs move via air currents to altitudes

ranging from 15 to 25 mi. There, they are

dissociated by ultraviolet light. The resulting

free chlorine atoms (Cl) decompose ozone

) into oxygen (O

), Cl + O

→ ClO + O

and are regenerated by interaction with free

oxygen atoms (O), ClO + O → Cl + O

. When

chlorine is regenerated, it is free to continue to

break down other ozone molecules.

Ground-level ozone (O

) motor vehicle

engines, power

plants, and industrial

boilers

Repeated exposure to ozone pollution for

several months may cause permanent

structural damage to the lungs. Because

ozone pollution usually forms in hot weather,

anyone who spends time outdoors in the

summer is at risk, particularly children,

moderate exercisers, and outdoor workers.

Sulfuric acid (H

) Hard surface

cleaners, metal

cleaners, pool

chemicals, car,

motorcycle, truck and

boat batteries

Burning sensation. Sore throat. Cough.

Labored breathing. Shortness of breath,

Corrosive. Redness. Pain. Blisters. Serious

skin burns, Abdominal pain. Burning

sensation. Shock or collapse.

Note: Some pollutants may not have direct health effects.

Choose one of the following atmospheric issues: air pollution, global warming, ozone depletion,

and acid deposition. Then, respond to the following:

• What air pollutants combine and contribute to this issue?

• Briefly describe the health and environmental problems caused by the selected

atmospheric issue.

• Provide one key solution to help either reduce the effects or recover from the

effects of the selected issue

The atmospheric issue I have chosen is ozone depletion. I chose this one because of what

information I found on the use of Freon. Personally I do not use my air conditioner in any of the

vehicles my family owns, I think it is a waste of gas and reduces the life of the motor. Once this

gas is released into the atmosphere it starts to break down the ozone, allowing more radiation in

and creating the global warming we are seeing. One solution to this problem would be to find a

better way to cool down a refrigerator and ones ac in their automobiles. With technology as

advanced as it is there has to be a better way for this to be done that does not help contaminate
