What is the purpose of risk characterization in risk assessment?

The purpose of risk characterization in risk assessment is to summarize the findings of the assessment, integrating the information from earlier steps of the risk assessment process, which typically include hazard identification, dose-response assessment, and exposure assessment. This step synthesizes the data and information gathered to provide a clear understanding of the nature and magnitude of risk associated with a particular exposure or hazard. It helps in translating complex scientific data into a format that aids decision-makers, stakeholders, and the public in understanding potential health risks associated with exposures.

Risk characterization not only provides a comprehensive summary but also contextualizes the implications of the risk, helping to convey the uncertainty involved. While other aspects, like evaluating health effects or identifying exposure scenarios, are critical steps in the overall risk assessment process, they do not encompass the broader role of risk characterization in tying together the findings to facilitate informed decision-making and risk communication.
