The process of organizing, evaluating, and communicating information about the nature, strength of evidence, and the likelihood of adverse health or ecological effects from particular exposures.
Integration of hazard identification, hazard characterization and exposure assessment into an estimation of the adverse effects likely to occur in a given population, including attendant uncertainties.
Description of the probabilities and consequences of a hazard, including the uncertainties in the estimates.
a synthesis and summary of information about a potentially hazardous situation that addresses the needs of decision makers and interested and affected parties. It describes the larger context in which the hazard occurs. Are other hazards incurred by the mitigation proposed? What is the magnitude of the new hazards? Are there social or economic effects not reflected in the risk assessment or cost-benefit analysis? Who is affected by the hazard(s), by the mitigation(s)
cancer risks and non-cancer hazard quotients are estimated during the risk characterization step of a risk assessment. In addition, uncertainty is evaluated and risk information is summarized.

assembles all results from the previous steps into an overall risk estimate. Example: an overall assessment of the risk of cancer evaluates the potency of a carcinogen together with its likely exposure to determine its relative risk.
The qualitative and/or quantitative estimation, including attendant uncertainties, of the probability of occurrence and severity of known or potential adverse health effects in a given population based on hazard identification, hazard characterization and exposure assessment.
An organized process used to evaluate, summarize, and communicate information about the likelihood of adverse health or ecological effects from particular exposures to a toxic chemical in the environment, i.e. how individuals or populations may be affected. It includes discussion of the kind of evidence it uses and how strong that evidence is. Risk characterization is the final step in the process of risk assessment. more
The integration of information on hazard, exposure, and dose-response to provide an estimate of the likelihood that any of the identified adverse effects will occur in exposed people.
Final component of risk assessment that involves integration of the data and analysis involved in hazard evaluation, dose-response evaluation, and human exposure evaluation to determine the likelihood that humans will experience any of the various forms of toxicity associated with a substance.
The last phase of the risk assessment process that estimates the potential for adverse health or ecological effects to occur from exposure to a stressor and evaluates the uncertainty involved.
