About This Chapter
Below is a sample breakdown of the Environmental Risk Analysis chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.
|Day||Topics||Key Terms and Concepts Covered|
|Monday||Environmental health: Overview||Go over environmental health definitions, discuss the four major kinds of environmental hazards for both outdoor and indoor environments, identify the risk assessment process, and examine techniques for managing possible health threats through the use of risk assessment|
|Tuesday||Toxicants||Describe the fields of epidemiology and toxicology; identify why certain groups, such as children, are more at risk of being harmed by toxicants; define and compare the following terms: biological magnification, persistence, and bioaccumulation|
|Wednesday||Disease||Compare the relationships between emerging diseases and environmental changes; discuss why environmental health organizations monitor public water supplies; identify how the following agents cause diseases: protozoa, bacteria, parasitic worms, and viruses|
|Thursday||Pollution and chemicals||Identify the goals of The Stockholm Convention on Persistent Organic Pollutants; review methodologies used for identifying cancer-causing chemicals; define the following pollutant and chemical concepts: dose-response curve; chemical mixtures; chemical interactions; synergistic interactions; additive interactions; antagonistic interactions|
|Friday||Precautionary principle||Discuss how this principle relates to how new products and technologies are introduced to the public|
1. What Is Environmental Health? Definition, Types & Sources
In this video lesson, you will learn about environmental health. You will also learn about threats to environmental health and how to distinguish between different categories of environmental hazards.
2. Understanding & Assessing Threats to Environmental Health
In this lesson you will learn how threats to environmental health are assessed. You will also learn how management decisions are made based on such threats and their risks.
3. Environmental Toxicants: Types, Sources & Effects
In this video lesson, you will identify different types of environmental toxicants. You will also learn about the harmful effects of these toxicants and how they travel from various sources.
4. Disease-Causing Agents in the Environment: Definition and Types
In this video lesson, you will identify different disease-causing agents. You will also explore examples of types of disease-causing agents and their effects on human health.
5. Using Indicator Bacteria to Monitor Public Water Supplies
In this video lesson, you will learn about indicator bacteria. You will understand how and why they are used to test for water contamination despite the fact that they are harmless and naturally occurring in human and animal systems.
6. Emerging Diseases Linked to Environmental Change
In this video lesson, you learn about why some diseases are increasing on Earth due to environmental changes. You'll also see examples of different types of diseases that are responding to environmental changes and how they are becoming more prevalent.
7. Magnification of Toxicants: Persistence, Bioaccumulation & Biological
In this lesson, you will learn about the persistence and magnification of toxicants in the environment. You will also learn about how these toxicants affect organisms as they move up the food chain.
8. The Stockholm Convention on Persistent Organic Pollutants
In this video lesson, you will learn about persistent organic pollutants and how they led to the Stockholm Convention on Persistent Organic Pollutants in 2001.
9. The Dose-Response Curve: Determining Health Effects of Environmental Pollutants
In this video lesson, you will learn about dose-response curves and how toxicologists measure the toxicity and effects of toxicants. You will also learn about how this data is applied to human health.
10. Assessing Chemicals for Cancer-Causing Agents
In this video lesson, you will identify sources of cancer-causing agents. You will also learn how scientists determine which substances and chemicals cause cancer in humans.
11. Interactions in Chemical Mixtures: Additive, Synergistic & Antagonistic
Chemical reactions occur constantly within our environment and even within our own bodies. Reactions can vary depending on the chemicals that are mixed together. This lesson explores the four most common reactions and offers examples for each.
12. Toxicants and Children: Why Children Are More Susceptible
Despite their small size, children are more susceptible to environmental toxicants. In this video lesson, you will learn why toxicants often have greater effects on children than adults.
13. The Precautionary Principle and New Technologies & Products
In this lesson, you will learn about the precautionary principle and how it applies to new technologies and products. You will also learn about how this principle is applied in different government regulations.
