MIEH 300: Essential Topics for the Midterm
What is Environment - correct answer ✔✔all that is external to the individual host. It can be divided into
physical, chemical, biological, social, cultural factors, any or all of which can influence health status in
populations
What is Health? - correct answer ✔✔State of complete physical, mental, and social well-being and not
merely the absence of disease or infirmity
What is Environmental Health? - correct answer ✔✔Theory and practice of assessing, correcting,
controlling and preventing factors in the environment that can adversely affect the health of present and
future generations
Factors responsible for community health - correct answer ✔✔Individual factors, individual behaviors,
public services & infrastructures, living & working conditions, social & economic & political factors
Environmental Health Factors - correct answer ✔✔Chemical, physical, biological, social/cultural
Exposure - correct answer ✔✔the contact between an agent and a receptor. The contact takes place at
an exposure surface over an exposure period
Exposure science - correct answer ✔✔the study of human contact with chemical, physical, or biological
agents occurring in their environments
Exposure assessment - correct answer ✔✔Determination or estimation of the magnitude, frequency,
duration, and route of exposure; characterization of exposed population; characterization of uncertainty
Agent - correct answer ✔✔any chemical, biological, or physical stressor capable of eliciting a biological
response
Medium - correct answer ✔✔the environmental medium in which agent is found (air, soil, water, food)
, Pathway - correct answer ✔✔the course an agent takes from the source to the receptor
Route - correct answer ✔✔the way an agent enters a receptor after contact (e.g. by ingestion,
inhalation, dermal application)
single agent/stressor exposure - correct answer ✔✔exposure of a receptor to a single specific agent or
stressor in one environmental medium and one route of exposure
Aggregate exposure - correct answer ✔✔the combined exposure of a receptor to a specific agent or
stressor from all sources across all routes and pathways
Cumulative exposure - correct answer ✔✔The total exposure of a receptor to multiple agents and/or
stressors by multiple routes/pathways
Applications of Exposure Assessment - correct answer ✔✔Understand the role of environmental
exposure in the etiology of disease
Support risk assessment
Identify and characterize susceptible populations
Tracking of environmental exposure
Environmental Health Paradigm - correct answer ✔✔1) pollution sources and environmental
concentrations
2)Fate and transport
Human susceptibility
3)Human exposure
Human susceptibility
4)Internal dose
Human susceptibility
5)Biologically effective dose
Human susceptibility
6)Health Effect
