Write a 1,400- to 1,750-word evaluation of the application of risk assessment in the Ch. 9 case study: “Risk Assessment of Chromium-Contaminated Soils: Twelve Years of Research to Characterize the Health Hazards”.
· Describe the case, the early investigation, and the resulting uncertainties.
· Describe the four steps of human health risk assessment: identify hazard, dose-response modeling, exposure assessment, and risk characterization or probability. What is your estimation of the short- or long-term damage and exposure to humans, environmental toxicants, or chemical hazards risk analyses that were applied in the case study?
· Evaluate the exposure and toxicity assessments and the subsequent risk characterization. What, for example, were the findings of the exposure and toxicity assessments? What are the implications? Evaluate the steps used in the risk assessment, the purpose, and conclusion.
· Summarize the practical implications of the risk assessment.
· Describe the costs versus benefits of a site remediation based on the risk assessment. Use the data presented in the case.
· Detail the management decisions that are part of cost and benefit analysis, and describe possible improvements that would further clarify the risk and cost comparisons in the case.
