Module 5, Closes Monday, February 18

A contaminant may change chemically over time and may move from place to place. You have some vocabulary and general notions about fate and transport of contaminants in the environment; and you probably realize that it can be a very complicated process. There are so many chemicals and so many environmental processes, that we can teach only a few specifics. For the exposure assessment portion of a risk assessments, we need to organize our data about the contaminant: its sources, routes, and receptors, in some logical fashion. Usually a Site Conceptual Exposure Model (SCEM) is the tool we use. Submodule 5A deals with exposure assessment and SCEMs. It is a fairly long submodule. There is a link below for a few extra pages on organic chemical terms and symbols which you might read. For your toxicology lesson, we'll continue with Tox Tutor III, which gives some fundamental terms about diseases and their effects at the cellular level.

There are 28 points for this module's homework. a.) 13 points for the auto-quiz you access through Blackboard, b.) 5 points for the discussion, c.) 5 points for your paper topic, and d.) 5 points for the message to the instructor. All are explained more below.

a.) The quiz is on Blackboard. The quiz is a matching quiz based on 5A. You can review a copy of the quiz before you go to the electronic quiz, Quiz, but it will not make sense to you until you complete 5A.

b.) For your discussion groups, I'd like you to relate your experiences (in a paragraph or two) if you have ever been made sick by an exposure to a chemical from the environment. (Exposure to chemical vices don't count.) If you have not personally been sick, have you observed some else who has? If you can't think of any, read the contributions of others in your group and comment. Please read and comment on at least one of your group members' experiences.

c.) Submit your paper topic. It does not have to be cast in concrete, but it should be where you intend to start. A"topic" is a little different than a "title." You can expound in a short paragraph, if you like. Put it in a Word document along with the message to the instructor.

d.) Send the instructor a message. Ask at least one question about the toxicology lessons you have been reading so far. We have not said much about that topic, yet. Also, ask at least one other question about the material in Module 5, and write a few lines about any problems you had accessing the material, quirks about how you browser handled the material, or point out any typo's or glitches in the material.
