The following case studies are provided to give you experience in completing risk assessments. These studies allow you to identify the process that one goes through in risk assessments. (This implies, “This is what the case study tells me, this is what I need to know, this is what I would do with the information once it is determined…Perhaps you should start out saying, “The first step I took…) The whole point of this process is to get you familiar with the components of the risk assessment process and to give you practice with trying to find the different components and then put them together to make conclusions. My approach to this assignment is to act like a detective. Ask questions of yourself, discuss where the questions lead you, what more questions are revealed once you have gathered the initial data, etc.

The final research project has you actually doing the process for a particular toxicant with you researching for the information you need.

FIRST THING: Also, though more important for stage 2, you will need to determine why you are doing the risk assessment. SPECIFICALLY WRITE OUT YOUR PURPOSE FIRST THING. In an accident case it might be to determine what the long-term health effects will be to those who were exposed but survived. It might be to determine how high the risks of exposure are to nearby residents, or if exposure were to happen, what the risks to them might be. In a workplace case the risk assessment might be to determine to what level the clean-up (of air, water, etc.) should be to protect human health. It might be to determine if any workplace accommodations need to be made. In a medically related case the risk assessment might be to characterize the risks to workers associated with a medically related accident or incident. Its purpose might be to determine the risks to the general public from an incident. If you narrow down your focus it will make how you go about dose response investigation and exposure assessment more straightforward.

You may NOT use any of these case studies for your research project.

Staged Project (Case Study 1), Stage 1: Define the purpose of the Risk Assessment. Apply the steps of hazard identification to identify the hazard in each case study. Be sure to discuss the evidence that led you to your decision about the identification of the hazard. If the case study doesn’t provide the evidence then discuss how you would go about getting the evidence you need and what source would you use. Discuss how the evidence supports your conclusion about the identification of the hazard. Keep in mind the information you need for toxickinetics and toxicodynamics.
