Lesson 3: Ecological Impacts of Hazardous Wastes


The main purpose of this lesson is to demonstrate the idea that the things we throw away may harm other organisms. This lesson uses a brainstorming activity, and a lab experiment testing the effect of toxins on brine shrimp. This lesson also introduces the major pathways through which hazardous waste enter aquatic and terrestrial ecosystems and provides an overview of the impacts of wastes such as heavy metal ions, strong acids or bases, and persistent organic compounds on plants and animals.
