2. ENV 420 Week 2 Learning Team Assignment Human Health Risk Assessment *************************************************** ENV 420 Week 3 Individual Assignment Occupational Risk Research Paper For more classes visit www.snaptutorial.com 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.

3. 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 3 Individual Assignment Time-of- Day Occupational Risk Paper or Podcast For more classes visit www.snaptutorial.com Write a 750- to 1,050-word paper or record a 10-minute podcast in which you address the following: Analyze the risk relationship between variable and night shift work to occupational accidents.

4. Choose one of the following examples or obtain approval from your instructor of other examples: Police shift work; Union Carbide and Bhopal, India accident; Shift worker and Chernobyl, Russia accident; or Three Mile Island, Pennsylvania accident. Address the following in your analysis: Industry risk Time of shift Length of shift Biological clock Stress Boredom Country or ethnicity Explain how risk assessment is applied differently between occupational and nonoccupational environments. *************************************************** ENV 420 Week 4 Individual Analyzing Ecological System (Ecology and Wildlife Risk Evaluation)

5. For more classes visit www.snaptutorial.com 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. ***************************************************

6. ENV 420 Week 4 Individual Analyzing Ecological Systems (Gulf Oil Spill Case Study) For more classes visit www.snaptutorial.com Write a 1,750- to 2,050-word analysis of the British Petroleum Oil Spill in the Gulf of Mexico. Complete the following in your paper: Describe the main events of the incident and the principle parties involved in a timeline. Describe the laws enforced at the time. List the ecological risks of the affected area at the time of the spill. Forecast what may be required of the oil industry relative to future risk assessments. How can economic value be allocated in this scenario? Describe the process of defining ecological value and discuss the application of probabilistic risk assessment methods in this case. Discuss the hazards and the risk uncertainties that can lead to a reanalysis of this case using probabilistic assessment. 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 this case? Establish a value for the ecological components in this case. Are there any tradeoffs between wildlife and development? Why or why not? How is this risk assessment actually determined? ***************************************************

7. ENV 420 Week 5 Learning Team Assignment Environmental Management Paper and Presentation For more classes visit www.snaptutorial.com Research a local environmental issue, such as one of the following: Municipal solid waste Household hazardous waste Potable water treatment Municipal sanitary waste treatment Carbon dioxide emissions Any other local environmental issue of interest, with faculty approval Include at least four outside references that describe the long-term costs and benefits that may affect decisions based on economic or social effects for your chosen environmental issue. Include an appropriate course of action based on your analysis of the local environmental risk assessment. Address all of the following in your evaluation: What are the long-term costs and benefits of your course of action for the local environmental issue? Determine relevant values of ecosystem variation due to any local climate change for your chosen environmental issue.

8. Develop a simple cost-benefit analysis and explain the no-action alternative. What are the economic and social benefits of your research? What is the local environmental impact? Conclude with a course of action on your community issue that is supported by your research, your risk assessment, and your cost comparisons. Format your paper consistent with APA guidelines. Create a 10-slide Microsoft® PowerPoint® with presenter’s notes to accompany your paper. Cite your sources for each slide. ***************************************************
