What is an exposure profile?
Exposure profile: the product of characterization of exposure in the analysis phase of ecological risk assessment. An exposure profile summarizes the magnitude and spatial and temporal patterns of exposure.
What are exposure characteristics?
Each of the exposure factors involves humans, either in terms of their characteristics (e.g., body weight) or behaviors (e.g., amount of time spent in a specific location, which affects exposure duration). These characteristics and behaviors can carry a great deal of variability and uncertainty.
What are the four methods of exposure assessment?
Exposure assessment is one of the four major steps in risk assessment; others include hazard identification, dose-response assessment, and risk characterization.
What is exposure in exposure assessment?
Exposure assessment is “the process of estimating or measuring the magnitude, frequency, and duration of exposure to an agent, along with the number and characteristics of the population exposed. Ideally, it describes the sources, routes, pathways, and uncertainty in the assessment.”
What is the main objective of exposure assessments?
Explanation: Major objective of exposure assessment is to estimate the risk caused by the exposure of a chemical contaminant to an individual and ecosystem.
How is exposure measured and monitored?
Data can be collected by directly monitoring an individual or indirectly, each method with advantages and disadvantages. Monitor individuals using some measurement device on their person or by taking biological samples.
What is the main objective of exposure assessment?
What are the four major exposure pathways and routes?
Routes of Exposure There are four routes by which a substance can enter the body: inhalation, skin (or eye) absorption, ingestion, and injection.
How do you do an exposure assessment?
Collect additional data and re-assess the exposure profiles as needed.
- 1) Gather Available Information and Data.
- 2) Define Similar Exposure Groups.
- 3) Profile the Exposure.
- 4) Determine the Acceptability of Exposure.
- 5) Collect Additional Information and Exposure Monitoring Data.
- Optimal Level of Protection.

Why is exposure assessment important?
Exposure assessment is critical to both understanding the scope of occupational safety and health problems, and confirming whether interventions are effective. Burden cannot be measured without appropriate and adequate exposure assessment methods to obtain baseline data and assess changes.
