Explore Air Quality

1. Which town has the highest Air Quality Index (AQI) forecasted for today? Cowtown, AZ AQI of 145

2. Why? Cowtown is near Phoenix (lots of traffic). They have had warm temps (~90F), high pressure, and little wind so pollutants accumulate.

Key Vocabulary

Use the Internet to help you come up with a definition for the following terms. You should add these definitions to your Air Pollution brochure “Sources of Air Pollution” panel. What would be good examples of each?

Point source pollution comes from a specific identifiable source (pipe, factory, wastewater treatment plant)

Nonpoint source pollution comes from unidentifiable or multiple sources (cars, many factories, farmland run off)

Ozone

Ozone is good in the stratosphere but bad in the troposphere. Human activities affect both types.

Textbook Resources

McDougall, p.A32

Human activities produce chemicals that destroy the ozone layer. CFCs

Some natural processes put chlorine into the stratosphere, but about85 percent of the chlorine there comes from human activity. Chemicals called chlorofluorocarbons (KLAWR-oh-FLUR-oh-KAHR-buhnz) have been manufactured for use in cooling systems, spray cans, and foam for packaging. These chemicals break down in the stratosphere and release chlorine and other ozone-destroying chemicals.

Human Activities affect the atmosphere

Create a 6-sided brochure about air pollution. Due by Tuesday at the beginning of class.

Include the following topics:• Title, name, core, and date• Human activity can cause air

pollution• Types & sources of air pollution

• Effects of air pollution • Air Pollution affects the ozone

layer • Ways to reduce air pollution

Use pages A27 - A33
