- The qualitative and quantitative evaluation of risks posed to health or the environment that arise from an activity, chemical use, or technology. The process includes describing potential adverse effects, evaluating the magnitude of each risk (e.g., the toxicity of a chemical), estimating potential exposure to the chemical or other hazard, estimating the range of likely effects given the likely exposures, and describing uncertainties.
- A scientifically based process consisting of the following steps: (I) hazard identification, (II) hazard characterisation, (III) exposure assessment and (IV) risk of characterisation.
