What Is Environmental Health? Definition, Types & Sources

1. What Is Environmental Health? Definition, Types & Sources

Environmental health is the understanding of all hazardous factors that impact the wellbeing of the environment and humans. Learn more about the different types of environmental hazards, including physical, chemical, biological, cultural and indoor.

Understanding & Assessing Threats to Environmental Health

2. Understanding & Assessing Threats to Environmental Health

For the health of humans and of the planet, it is important to understand the issues that threaten the environment. Learn more about how environmental risk assessment, how human health can be helpful in assessing risks, and how such risks are managed.

Environmental Toxicants: Types, Sources & Effects

3. Environmental Toxicants: Types, Sources & Effects

Environmental toxicants are toxic agents found in many things people come in contact with on a daily basis. Learn about the four main types of toxicants, including mutagens, allergens, neurotoxins, and endocrine disruptors, sources of toxicants like plastics, household cleaners, solvents, detergents, and their detrimental effects on the enviroment.

Disease-Causing Agents in the Environment: Definition and Types

4. Disease-Causing Agents in the Environment: Definition and Types

Disease-causing agents in the environment are biological pathogens that can cause or spread illnesses. Explore the definition of disease-causing agents and learn about different types of disease-causing agents such as viruses, bacteria, protozoa, and parasitic worms.

Using Indicator Bacteria to Monitor Public Water Supplies

5. Using Indicator Bacteria to Monitor Public Water Supplies

Indicator bacteria are harmless bacteria that are used to monitor public water supplies to determine if the water has been contaminated or is safe to drink. Learn about the types of indicator bacteria and the benefits of using them in testing water supplies for the presence of harmful bacteria.

Emerging Diseases Linked to Environmental Change

6. Emerging Diseases Linked to Environmental Change

Environmental changes, such as temperature increases, have been linked to new, emerging diseases found around the world. Review environmental changes in water and understand how these can cause disease, including zoonotic diseases. Explore the impacts of bird migration, contact with pigs, and human population increases on emerging diseases.

Magnification of Toxicants: Persistence, Bioaccumulation & Biological

7. Magnification of Toxicants: Persistence, Bioaccumulation & Biological

Magnification of toxicants occurs when toxic substances in the environment bioaccumulate in animal tissues, creating drastic effects. Learn about the persistence of toxicants, how toxicants build up in tissues, how bioaccumulation works, and the impact of the book ''Silent Spring.''

The Stockholm Convention on Persistent Organic Pollutants

8. The Stockholm Convention on Persistent Organic Pollutants

In 2001, the Stockholm Convention on Persistent Organic Pollutants (POPs) was convened to set global guidelines for discontinuing their use. Learn about the 12 POPs that were identified at the convention, and discover why POPs can be especially dangerous when they accumulate in animal tissue and begin to move up the food chain.

The Dose-Response Curve: Determining Health Effects of Environmental Pollutants

9. The Dose-Response Curve: Determining Health Effects of Environmental Pollutants

The dose-response curve represents the results of repeated doses of a toxicant on test animals. Explore how scientists determine the lethal and non-lethal health effects of toxicants and other environmental pollutants in this lesson.

Assessing Chemicals for Cancer-Causing Agents

10. Assessing Chemicals for Cancer-Causing Agents

Cancer-causing agents are hazardous substances and chemicals that increase the risk of contracting cancer. Learn about cancer-causing agents, explore natural and non-natural sources of carcinogens, and review how scientists assess chemicals to determine if they have the ability to cause cancer.

Interactions in Chemical Mixtures: Additive, Synergistic & Antagonistic

11. Interactions in Chemical Mixtures: Additive, Synergistic & Antagonistic

Chemical reactions occur when two or more substances combine to create a different substance. Discover the different types of interactions in chemical mixtures: additive, synergistic, antagonistic, and potentiating.

Toxicants and Children: Why Children Are More Susceptible

12. Toxicants and Children: Why Children Are More Susceptible

Because children are smaller than adults, they are more susceptible when they are exposed to the same amount of a toxicant, as they're getting a higher concentration for their body weight. Investigate why children are more physically susceptible to toxicants and why their rate of exposure is higher than that of adults.

The Precautionary Principle and New Technologies & Products

13. The Precautionary Principle and New Technologies & Products

The precautionary principle states that an action should not be taken unless its consequences are understood. Explore the precautionary principle and the way it affects how governments around the world employ rules for innocence and guilt, particularly surrounding the complicated issue of new technologies and products.
