At the end of the this session, students are expected to have a full appreciation of the issues covered in this second half of the lecture. They should know that worldwide some POCs are still at levels far exceeding their screening values (in some places by 30-fold+). They should realize that the type of risk analysis conducted in this lecture is far from flawless; it is only exploratory in nature. They should also understand the additional concern that POCs have a tendency to bioaccumulate in humans. Finally, students should be familiar with the fact that effective strategies for this type of prevention could/should come from the following directions: environmental health policy; regulatory and research activities; residue monitoring programs; and self awareness/prevention. Of these, the last approach appears to be most effective.
