Lead is a health hazard for all humans. You can not see or smell lead, and often, you can not taste it. We are surrounded by lead in our environment, however, it does not mean that you will be poisoned. The purpose of this unit on “Lead Contamination: Practices, Policies, and Ethics” is to provide information, awareness, and activities to teachers and students in the middle grades, 5-8; to the seriousness of the problem of lead toxins in the environment.
