Major Principles and Concepts of Risk Assessment

  • Chapter
  • First Online:
The Practice of Consumer Exposure Assessment

Abstract

Risk has two components: a known threat, which in the context of toxicology is called a hazard, and an exposure situation. In toxicology, risk assessment requires quantification of the two components: (1) the hazard which is the possible health impairment, given by the inherent toxicological and physicochemical properties of a substance. This is called hazard identification, and combined with dose-response characterisation it becomes, hazard assessment, and (2) the exposure which has to be assessed and quantified. The ratio of hazard assessment and exposure assessment is the probability that under a given exposure situation, a specified health impairment will materialise.
