HEALTH ECU EXAM ONE UPDATED QUESTIONS AND
CORRECT ANSWERS
Question:
1. Environmental Health
Answer:
-Aspects of human health, including quality of life, that are determined by physical, chemical,
biological, social, and psychosocial processes in the environment -Theory and practice of assessing,
correcting, controlled, and preventing those factors in the environment that can potentially adversely
affect the health of present and future generations
Question:
2. Rachel Carson
Answer:
-One of the first people to realize the global dangers of pesticide abuse (DDT). -Wrote Silent Spring
-Bird eggshells cracking and breaking because the pesticides were weakening their shells
Question:
3. Earth Day
Answer:
April 22nd
Question:
4. Four Subdivisions of Environmental Health
Answer:
1. Environmental Science
2. Environmental Epidemiology
3. Environmental and Occupational Medicine
4. Environmental Toxicology
Question:
5. Environmental Science
Answer:
-Integrates physical, biological, and information sciences -Ecology, biology, physics, chemistry, plant
science, zoology, mineralogy, soil sci-ence, atmospheric science, etc. LACv in Environmental
Science: Combined knowledge of biology, ecology, and plant science (among others) to determine
the habitat of Aedes triseriatus the main vector of La Crosse virus
Question:
6. Environmental Epidemiology
Answer:
-Concerned with determining how environmental exposures impact human health -Risk factors that
affect incidence, prevalence, and geographic range of health conditions -Surviellence -Risk
assessment -Risk communication LACv in Epidemiology: Retrospective case study comparing
people with the LACv virus and if it was common in siblings
, Question:
7. Environmental and Occupational Medicine
Answer:
-Study of effects upon human beings of external physical, chemical, and biological factors in the
general environment -Evaluation, management, and study of detectable disease or adverse health
outcomes from exposure to external physical, chemical, and biological factors in the general
environment -In 1700 Bernardini Ramazzini publishes first edition of Diseases of Workers LACv in
Environmental and Occupational Medicine: Determine and treat the effects of LACv in the
environment, treating pediatric pexposure to LACv
Question:
8. Environmental Toxicology
Answer:
-COncerned with harmful effects of various chemical, biological, and physical agents on living
organisms -Ecotoxicology: harmful effects of toxicants at population and ecosystem levels -Silent
Spring: Rachel Carson LACv in Toxicology: -Use repellants to avoid bites, but what is the effect of
repellent on human health? -Toxicokinetics: ADME factors -Toxicodynamics: Mechanism and mode
of action, ex. DNA damage
Question:
9. Who is most im-pacted by the en-vironment?
Answer:
-Low income countries: greatest share of environmental disease -Occupational risks and injuries
slightly higher in men -Smoke from cooking, or carrying water lead to higher traditional exposures in
women -Children five and under and adults between 50 and 75 most affected by the environment
Question:
10. #1 Cause of Death From Envi-ronment
Answer:
-Stroke, accounts for 2.5 million deaths -#2 is ischemic heart disease, 2.3 million
Question:
11. Environmental Exposures
Answer:
1. Acute: Occurs soon after exposure
2. Chronic: Takes place over a period of time (cause may be difficult to determine)
Question:
12. Essential Services of Environmental Health
Answer:
1. Assessment
-Monitor health -Diagnose & investigate
2. Policy Development
-Inform, Educate, Empower -Mobilize community partnerships -Develop policies
3. Assurance
-Enforce laws -Link to/provide care -Assure competent workforce -Evaluate
4. Research!
