ENV 420 Week 1 Individual Assignment Risk Assessment Worksheet NEW
Part A: Ecological Risk Assessment Framework
Provide a 350- to 700-word response answering the following questions:
- Describe the four main topics of the framework for ecological risk analysis described in Human and Ecological Risk Assessment. The response must involve problem definition analysis, characterization, and management decision making. You may refer to the framework in ecological risk assessment as shown in Figure 6.1 (Ch. 6) in Human and Ecological Risk Assessment.
- How do the four main topics of the framework interrelate?
- Why is this framework important to a risk assessment? How is it used?
Part B: Historical Development of Risk Assessment Summary
Write a 350- to 700-word summary of at least three risk assessment innovations that were changed or developed in the past 100 years.
- Use Table 1.1 (Ch. 1) in Human and Ecological Risk Assessment as a guide to understanding the origins of ecological and human risk assessment beginning with the industrial revolution.
- Cite at least two outside sources to summarize the risk assessment innovations.
Format your paper consistent with APA guidelines.

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.
Format your case study evaluation consistent with APA guidelines.

ENV 420 Week 3 Individual Assignment Occupational Risk Research Paper NEW
Choose a lead, asbestos, or silica contaminant hazard for occupational risk assessment research.
Research your chosen occupational risk and analyze the assessments of human exposure to contaminants and evaluate how these assessments were conducted.
Write a 750- to 1,050-word research paper in which you complete the following:
Describe how the risks of exposure to a specified concentration of your chosen hazard may be calculated differently for public household exposure versus workplace occupational exposure.
Answer the following in your paper:
In general, how does the application of occupational risk assessment differ from ecological or human health risks? For example, occupational risks may be based on a 10-hour workday, whereas animals or insects might have different ecological exposure risks and life spans.
How might your chosen human health risk hazard differ in terms of risk if it were ecological rather than a nonoccupational exposure?
Identify the acceptable exposure limits for affected populations in occupational and nonoccupational environments. Explain the reasons for the differing risk assessment models and explain the justification for the differences.

ENV 420 Week 4 Individual Analyzing Ecological System (Ecology and Wildlife Risk Evaluation) NEW
Write a 1,700- to 2,050-word analysis of the Los Alamos National Laboratory in Case Study 19.5 and the Ch. 22 case study, which predicts the effect of pesticides on aquatic systems. Complete the following in your paper:
Describe the process of defining ecological value using the specific examples developed in the case study of the Los Alamos National Laboratory from section 19.5. Compare section 19.5 with the application of probabilistic risk assessment methods in the case predicting the effect of pesticides on aquatic systems in Ch. 22. Begin by briefly describing the Ch. 22 case, the hazards that were studied, and the risk uncertainties that lead to a reanalysis of the case using probabilistic assessment.
Explain how the case from Ch. 22 applied the risk assessment framework and hypothesize improvements in the analysis process.
Describe how the risk assessment correlated to observed field studies and evaluate the importance of this type of correlation in general for all risk assessment efforts.
What are the ecological and social values of concern in each case?
Establish a value for the ecological components in each case. Are there any tradeoffs between wildlife and development? How is this risk assessment actually determined?
Hypothesize how the probabilistic analysis process could be improved in the Ch. 22 case study to predict ecological risks for environmental contaminants.
