  1. Environmental Health Chapter 9 Environmental Science

  2. Section 1 • Central Case • What is the relationship between environmental health and our own health?

  3. Section 1 • Objectives • 1. List the types of environmental health hazards • 2. Compare and contrast epidemiology and toxicology • 3. Describe the reasons why individuals respond differently to the same environmental hazards • 4. Discuss risk assessment

  4. Section 1 • In what ways can a leaky sewer line threaten your health? • Think on your then share with a partner

  5. Section 1 • The study of how environmental factors affect human health and our quality of life is called: • Factors that threaten or are harmful to human health are called:
