This week discusses chemical exposures and human and environmental health. We often take for granted that we are exposed to chemicals every day and everywhere as we breathe, touch, and eat them. Some of these chemicals are harmful to human health, like lead and asbestos, while others are beneficial, like those found in medicines. Some chemicals are toxic at all levels of exposure, while others may be harmful at a certain threshold and beneficial at another.
Material for Week 7:
This week, we will focus on chemicals that have harmful effects. We'll explore how you and others are exposed to chemicals through your everyday geographies, and will consider the relationship between human and environmental health. You will:

As you go through this lesson, consider:
- How might my chemical exposures be different, or the same, from someone living in another place?
- How might someone from a different background be exposed to different chemicals?
- How do my consumer choices influence others’ chemical exposures? Environmental exposures?
- Why is it important to trace chemicals in the environment?
