Document Summary
Or probability of suffering harm from a hazard. Why risk assessment: must sometimes take action without full scientific undertstanding of hazard o o. Risk assessment sets default procedues for bridging gaps in scientific understanding. Basic framework: evaluate exposure and toxicity; bring this info together to characterize a health risk. Phase 2: characterization o o o o o: management plant. Scientific process in estimating how much harm a particular hazard can cause. Help identify risks that are easily reduced or eliminated. Help clarified what is known and not known about situation. Ontario ministry of environment o o o o o. 9. problem definition identify contaminant receptor analysis pathways analyses exposure assessment toxicity assessment risk characterisation uncertainties critique. Complex mixture with a few compounds driving toxicity. Organism, species or groups of species exposed to stressor. Length of exposure (life time, 20 years latency for cancer) Determine environmental fate that results in exposure to receptors.
