Application of toxicology in the field of environmental health and safety
Dose-response assessment is a critical element of hazard characterization. Dose-response assessment characterizes the quantitative relationship between exposure (usually determined in toxicity studies) and the occurrence of adverse health effects. Typically applied or administered dose, rather than effective tissue dose, is used to develop the dose-response relationship. As a rule, the higher the dose, the greater the frequency or intensity of the adverse reaction to a chemical. Risk management is the macro-level process of assessing, analyzing, prioritizing, and making a strategy to mitigate threats to an organization`s assets and earnings. Risk assessment is a meso-level process within risk management.
