L5 Exposure Assessment Quiz Env Epid

What are the first five steps included in exposure assessment?

• Evaluation of the health outcomes to identification of the source

• Estimation of the absorbed dose to identification of the source

• Identification of the source to estimation of the absorbed dose

• Identification of the source to evaluation of the health outcomes

Which of the following is an example of an acute exposure?

• Outdoor air pollution

• Eating undercooked chicken contaminated with Salmonella

• Exposure to contaminants in drinking water

• Occupational exposures to solvents

What does bioavailability refer to in exposure assessment?

• Amount of a substance reaching a target organ

• Fraction of the administered dose that reaches the central compartment

• Amount of a substance crossing a route barrier into the body

• Amount of substance that is inhaled or consumed

Why is exposure assessment important in risk assessment?

• To increase the toxicity of chemicals

• To eliminate all hazards from the environment

• To establish dose-response relationships in controlled environments

• To determine factors that put segments of the population at higher risk to chemical toxicity

What are the three elements of exposure assessment?

• Transportation, transformation, and fate processes

• Exposure, ingestion, and bioavailability

• Intake, uptake, and internal dose

• Dose, frequency, and route of exposure

Which of the following is an example of a chronic exposure?

• Outdoor air pollution

• Spilling acid on your hand

• Visiting a nail salon once a month

• Eating undercooked chicken contaminated with Salmonella

What is the impact of the duration of exposure on adverse consequences?

• Long-term exposure is less likely to have adverse effects

• Short-term exposure is more likely to have adverse effects

• Duration of exposure has no impact on adverse consequences

• Long-term exposure is more likely to have adverse effects

What is the definition of dose in exposure assessment?

• Amount ingested or inhaled

• Amount available at a boundary

• Amount reaching a target organ

• Amount crossing a route barrier into the body

Which of the following is an example of a time-varying exposure?

• Exposure to contaminants in drinking water

• Diet and exercise

• Occupational exposures to solvents

• Radon in one's basement

What is the main purpose of exposure assessment in epidemiology?

• To study the induction, latency, and critical review of exposure

• To assess the status and trends of exposure

• To establish dose-response relationships in the real world

• To determine the factors that put segments of the population at higher risk to chemical toxicity
