EPA Risk Assessment Review Process


On a conceptual level risk characterization is very simple, consisting of the bringing together of two risk components, hazard and exposure. Risk assessment is the bringing together the probabilities of hazard and exposure to produce an understanding of the likelihood of some type of adverse outcome. The process involves three components: data gathering to estimate the hazard and exposure, followed by characterization (combining the factors) to produce an estimate of the magnitude and probability of the anticipated adverse effect.
