One Health Approach

Recognizes that the health of the people are closely connected to the health of animals and our shared environment. - CDC

2
New cards

Examples of One Health Approach

Animals: Vaccinating animals for rabies will protect human health

Environment: The soil quality affecting crop growth.

3
New cards

The Epidemologic Triad

The interactions between the susceptible host (the person) the agent which causes the harm (agent/contaminant) and environment which brings the two together.

4
New cards

Example of The Epidemologic Triad

Malaria

  • Agent: parasite that will CAUSE the malaria

  • Environment: The AREA which supports mosquitos that carry the parasite.

  • Host: Person who becomes affected by malaria.


5
New cards

Examples of Epidemologic Triad (Chemical Exposure)

  • Agent: the chemical a person is exposed too

  • Environment: The contaminated environment that contains the chemical

  • Host: The person exposed to the chemical

Sources of Environmental Chemical Contamination

Can be natural: not caused by humans, such as:

  • volcanoes

  • soil deposits

  • natural seepage

  • fires

Can also be anthropogenic (caused by humans):

  • most of pollution

New cards

Examples of Chemical Contaminants in Air

  • SO2 (Sulfur Dioxide)

  • VOCS (Volatile Organic Compounds)

  • Nitrogen Oxides (NOx)

  • Ozone (O3)

  • Carbon Monoxide (CO)

  • Lead (Pb)

  • PM

New cards

Examples of Chemical Contaminants in Water

Chemical Contaminants:

Inorganic contaminants: As,Pb,Hg

Organic contaminants: (contains carbon)

Waterborne Illness

  • Protozoan parasite: Cryptosporidium

  • Hepatitis A

  • Cholera

New cards

Bioaccumulation

The accumulation of a toxic chemical in the tissue of a particular organism

10
New cards

Biomagnification

Special type of bioaccumulation that occurs through a food chain, results in a dramatically increasing concentrations of a toxic chemical in the bodies of animals as you go up a food chain.

New cards

Choices to Avoid Concerning Mercury

  • King Mackerel

  • Marlin

  • Orange Roughy

  • Shark

  • Swordfish

  • Tilefish (Gulf of Mexico)

  • Tuna, bigeye
