Chapter 18:  Air Pollution


Section 1:  What Is the Nature of the Atmosphere?

​Concept 18-1:  The two innermost layers of the atmosphere are the troposphere, which supports life, and the stratosphere, which contains the protective ozone layer.

Section 2:  What Are the Major Outdoor Air Pollution Problems?

Concept 18-2:
 Pollutants mix in the air to for industrial smog, primarily as a result of burning coal, and to form photochemical smog, caused by emissions from motor vehicles, industrial facilities, and power plants.

Section 3:  What Is Acid Deposition and Why Is It a Problem?

Concept 18-3:
 Acid deposition is caused mainly by coal-burning power plants and motor vehicle emissions, and in some regions it threatens human health, aquatic life and ecosystems, forests, and human-built structures.

Section 4:  What Are the Major Indoor Air Pollution Problems?

​Concept 18-4:
 The most threatening indoor air pollutants are smoke and soot from the burning of wood and coal in cooking fires (mostly in less-developed countries), cigarette smoke, and the chemicals used in building materials and cleaning products.
Section 5:  What Are the Health Effects of Air Pollution?

Concept 18-5:
 Air pollution can contribute to asthma, chronic bronchitis, emphysema, lung cancer, heart attack, and stroke.


Section 6:  How Should We Deal with Air Pollution?

Concept 18-6:
 Legal, economic, and technological tools can help us to clean up air pollution, but the best solution is to prevent it.


Section 7:  How Have We Depleted Ozone in the Stratosphere and What Can We Do About It?

Concept 18-7A:  Our widespread use of certain chemicals has reduced ozone levels in the stratosphere and allowed more harmful ultraviolet radiation to reach the earth's surface.

Concept 18-7B:  To reverse ozone depletion, we must stop producing ozone-depleting chemicals and adhere to the international treaties that ban such chemicals.
