Already Graded A+
Environmental Health ✔Correct Answer-Comprises those aspects of human health, including
quality of life, that are determined by physical, chemical, biological, social, and psychosocial
factors in the environment. It also refers to the theory and practice of assuming, correcting,
controlling, and preventing those factors in the environment that potentially can affect
adversely the health of present and future populations.
In the past, population growth presented challenges such as: ✔Correct Answer-1) Adequate
quality food/water*
2) Waste production/removal/disposal
3) Infectious disease
4) Safety
5) Industry/economy/capacity
Common occupational respiratory diseases: ✔Correct Answer-1) Asbestosis:
- Previously used as an insulator
- Inhaled fibers
- Causes mesothelioma and bronchogenic carcinoma
- Blue asbestos is the most toxic
2) Silicosis:
- Sand inhalation via dust (dirt which generates silicic acid and kills macrophages - finally dead
cells are replaced with scar tissue
- Inflammatory lung disease
3) Coal workers' pneumoconiosis:
- "Black lung disease"
- Miners inhaling coal dust - producing respiratory deficits and fibrosis
- Chronic obstructive lung disease
Toxicity: Acute and Chronic ✔Correct Answer-Acute: Fast & temporary
Chronic: Prolonged
The concept, "The dose makes the poison" ✔Correct Answer-All elements are toxic to some
quantifiable degree
LD50 ✔Correct Answer-The amount (dose) of a chemical which produces death in 50% of a
population of test animals to which it is administered to via ingestion or skin application
(mg/kg)
, LC50 ✔Correct Answer-Concentration of an environmental chemical in which exposure to
causes death in 50% of the population
What is the goal of metabolism? ✔Correct Answer-To detoxify
What influences metabolism? ✔Correct Answer-Age, weight, Comorbidities
Routes of entry ✔Correct Answer-1) Inhalation
2) Absorption
3) Ingestion
4) Injection
NOAEL ✔Correct Answer-High dose that did not cause a response
LOAEL ✔Correct Answer-Lowest dose that did not cause a response
Demographic Transition ✔Correct Answer-1) Stage 1: Stable pattern of high fertility and high
mortality
2) Stage 2: As mortality declines, population grows w/ younger share of population increasing
3) Fertility declines, population growth slows and older share of population increases
4) Stage 4: Fertility and mortality rates stabilize - population maintains its size
5) Stage 5: Lower fertility and an aging population result in an overall decreasing population
Epidemiologic Transition ✔Correct Answer-As cause of death shifted from communicable to
non-communicable disease, populations began living longer
Interaction between poverty, environmental degradation, and high fertility ✔Correct Answer-
Poverty leads to environmental degradation (including lack of contraception) which leads to
high fertility (including dwindling resources + more people) and back to poverty
Environmental Justice Part 1 ✔Correct Answer-The equal treatment of all people in society
irrespective of their racial background, country of origin, and SES
Environmental sustainability ✔Correct Answer-Adheres to the philosophical viewpoint that a
strong, just, and wealthy society can be consistent with a clean environment, health ecosystem,
and a beautiful planet
The Polluter Pays Principal ✔Correct Answer-The polluter should bear the expenses of
carrying the pollution prevention & control measures to ensure the environment is in an
acceptable stage
Steps of the policy cycle ✔Correct Answer-1) Policy definition/formulation
2) Agenda setting
3) Policy establishment
