Document Summary
Exposure assessment: the risk assessor estimates how much exposure the populations of concern have to the chemicals of concern. Hazard identification is a qualitative evaluation of toxicity with the purpose of establishing the scope of a chemical"s health effects. Dose-response assessment quantifies the relationship between the dose and the effect, it characterizes the dose-response curve for specific toxic effects. The risk characterization step brings together information on exposure with information on toxicity at different exposures, allowing the risk assessor to estimate risks to human health: risk assessments for noncancer effects of a chemical: The exposure assessment first identifies populations exposed to the chemical of concern. This considers all important sources of exposure such as the pathways and routes of exposure as well as the physical and chemical properties of the chemical. The hazard assessment is the qualitative step in toxicity assessments which establishes a range of noncancer health effects of a chemical.
