Module 10 closes March 27
The output of the risk assessment is called the "risk characterization." Here you state the probability and severity of the harm. A very important part of the risk characterization is a "statement of uncertainty." This module will develop some concepts important to the statement of uncertainties. Module 10A deals with some mathematical concepts, and 10B some biological concepts, especially regarding carcinogens. In module 10C we will review some chemicals that have some special rules or customs regarding them: lead, PCBs, asbestos, PAHs, dioxins and furans. You will need to use Microsoft Excel for this module. The closure module from last class has some good questions and good (I hope) answers, including some links to other sites.

There are 25 points for this module's homework. a.) 15 points for the auto-quiz you access through Blackboard, b.) 7 points for the discussion, and c.) 3 points for the message to the instructor. All are explained more below.
a.) Here is a text copy of the homework quiz.
b.) By now you should be into your paper that discusses a risk assessment. Take a paragraph or three to tell your group about the uncertainties of that risk assessment and how it was reported. Are the uncertainties related to site analysis, health effects, concentrations at the receptor, or....? Do this in a word file. Read at least two of your group's entries. Your grade for this discussion will be based on an evaluation of your entry by the instructor and your contribution to the discussion. No free rides this time, so first one up will have to come back later and do some commenting.
c.) Send the instructor a message. Ask at least one question about uncertainties.
Be sure to read the Old Closure first. Also, please point out any problems,
typos, glitches in the material.
