Assignment: Risk Management
I. We frequently use the term "de minimis risk" as a guideline.
i. Why is that considered an acceptable appropriate action level.
ii. What is the magnitude of this "de minimis" risk?
iii. List 3 examples of activities in everyday life that constitute de minimis risk and also indicate why we utilize this strategy for risk assessment. (example: eating peanut butter)
II. Estimate the risk-based screening level (RBSL) of toluene (a noncarcinogen) in a drinking water well assuming the water from the well is used for ingestion only. The reference dose for toluene is 0.2 mg/kg day. Assume residential conditions, an acceptable hazard quotient (HQ) of 1, exposure duration of 20 years, and an exposure frequency of 365 days/year.
III. Discuss the historical evolution of the risk assessment process in the Federal Government. Bs sure to include the significant events in the US-EPA and the role of the National Research Council. (This should take 1+ pages to accomplish)
IV. Discuss the three types of Risk. How do the each of these impact "Risk Perception" in the general population? Use an example of each type to illustrate risk perception and whether true risk is under or over perceived.
V. Define and discuss the Hazard Identification (HI) process.
i. Be sure your answer differentiates between HI and Risk Assessment (RA). Use the Delany Clause as an example of how HI and RA are different.
ii. Create (and discuss) a scenario where some future toxin (environmentally ubiquitous and potentially toxic at low levels) could create potential problems for using HI, instead of RA to set policy. (PFOS might be a good example) This should take 1+ pages to accomplish.
Format your assignment according to the following formatting requirements:
i) The answer should be typed, using Times New Roman font (size 12), double spaced, with one-inch margins on all sides.
ii) The response also includes a cover page containing the title of the assignment, the student's name, the course title, and the date. The cover page is not included in the required page length.
iii) Also include a reference page. The Citations and references must follow APA format. The reference page is not included in the required page length.
