Quantitative risk assessment toxicology. In quantitative risk assessment an annualized loss expectancy ALE may be used to justify the cost of implementing countermeasures to protect an asset. This may be calculated by multiplying the single loss expectancy SLE which is the loss of value based on a single security incident with the annualized rate of occurrence ARO which is an estimate of how often a threat would be.

Risk assessments of veterinary drugs residing in foods are performed by following the integrative steps of hazard identification hazard characterization exposure assessment and risk characterization. At the step of hazard identification known or potential adverse health effects in humans are identified which are induced by a veterinary drug or its metabolites that may be present in a. Chemical risk assessment basics part 3.

Risk Hazard x Exposure. When it comes to chemical management a distinction must be made between hazard and risk. Hazard defines the inherent property of a chemical having the potential to cause adverse effects when an organism system or population is exposed to that agent.
