Importance of this Unit to the Course

Certain chemicals manufactured for commercial use do not occur in nature. When these chemicals are released into the environment they may have unintended consequences under conditions or at locations not considered in product safety tests. This unit provides information on such chemicals so that we have scientific basis for discussing possible need for regulatory action and public policy as will be discussed in Block 3.
