Title: Chapter 19: Hazardous Chemicals: Pollution


1
Chapter 19 Hazardous Chemicals Pollution
Prevention
  • Sustainability, Stewardship, and Sound Science

2
Hazardous Materials
  • Are one or more of the following
  • Toxic
  • Reactive
  • Ignitable
  • Corrosive

3
Mercury and Lead
  • They are heavy metals which can cause
  • Mental impairment


4
Halogenated Hydrocarbons
  • Organic compounds with a halogen (bromine,
    iodine, ect.) replacing a hydrogen
  • Used as pesticides
  • Used to make plastic
  • Resistant to biodegradation

5
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

6
Love Canal, NY
Love Canal, New York
  • 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

7
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.

8
  • Toxicology Chemical Hazards
  • Dose
  • Food Chains

9
  • A History of MISmanagement
  • Land disposal
  • Injection
  • Scope of the Problem

10
  • Cleaning Up the Mess
  • Water
  • Superfund (NOT superFUN) Sites

11
  • Broader Issues
  • Environmental Justice (Grace)
  • Prevention Sustainability

12
Toxicology Chemical Hazards
  • Dose Response Threshold
  • Threshold Level
  • The Nature of Chemical Hazards HAZMATs
