2. Chapter 19: Hazardous Chemicals: Pollution & Prevention Sustainability, Stewardship, and Sound Science

3. Hazardous Materials Are one or more of the following: Ignitable Reactive Corrosive Toxic

4. Mercury and Lead They are heavy metals which can cause Mental impairment

5. Halogenated Hydrocarbons Organic compounds with a halogen (bromine, iodine, ect.) replacing a hydrogen Used as pesticides Used to make plastic Resistant to biodegradation

6. Chlorinated Hydrocarbons Chlorinated hydrocarbons Are synthetic organic compounds Dioxin Mainly caused by burning PVC pipe (medical waste) Linked to cancer. Also an endocrine disruptor. Recall Alligators …

7. Love Canal, NY Problem first discovered in 1978 The government allowed housing to be build over the toxic waste dump First national emergency in the US because of toxic waste Led to the superfund legislation. Superfund sites: $ comes from taxes on chemical industries 50% of the $ spent on legal costs Love Canal, New York

8. National Priorities list Includes sites that are: The greatest threat to health and the environment Toxic waste generated by households should be handled by toxic waste pick ups and public education.
