Analyzing Environmental Risks - Chapter Summary
Our environment represents a major contributing factor to our overall health and well-being. These lessons discuss the many aspects of our environment that may put our health at risk, such as toxins, pollutants, diseases, and more. As you use our study materials for this topic, you can be certain that everything we offer has been carefully prepared by experts. Our instructors have extensive experience in the fields of public health and environmental studies, and they have built these lessons to include the most up-to-date information, packed full of keywords, definitions, and real-world examples. The instructors have designed this chapter to teach you about the following topics:
- Determining environmental health status
- Environmental health threats and hazards
- Types of environmental toxicants and their impact
- Different types of disease-causing agents
- Applications for indicator bacteria with public water supply monitoring
- Connections between emerging diseases and changes in the environment
- Toxicant magnification
- Pollutant discussions at the Stockholm Convention
- Examining environmental pollution to determine health effects
- Toxicants and child susceptibility
- Applying the precautionary principle to new products
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. 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.
11. 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.
