Elements of
Environmental Health

    Living systems require
     environmental resources for
     survival
     •   Air
     •   Water
     •   Nutrients (Food)
     •   Shelter
     •   Social Interaction




                    5
Elements of
Environmental Health

    Living systems require
     optimum levels of resources
     for survival
     • Air
     • Water
     • Nutrients
        – C, H, N, P
     • Trace Metals
        – Zn, Cu, Cd, Fe




                   6
Elements of
Environmental Health

    Living systems are sensitive
     to un-needed/undesirable
     (harmful) resources
     • Volcanoes
        – H2S, CO2, Toxic metals, etc.
     • Hurricanes
        – H2O, Wind
     • Earthquakes
     • Industrial Pollution




                    7
Elements of
Environmental Health

    Higher order living systems
     have adaptive strategies for
     survival
     • Seeking
        – Food
        – Shelter
        – Social interactions
     • Avoiding
        – Danger
        – Hazardous materials




                    8
Elements of
Environmental Health

    Exceeding optimum useful
     levels of environmental
     resources or exposure to
     harmful resources causes
     system stress
     • Reduced wellness
     • Onset of disease
     • Community health problems




                9
Management of High
Standards of living

  Post industrial economic
   theory and management
   practices have focused on
   short term gains and have
   often overlooked or ignored
   long term costs
  Environment receives
   cultural byproducts
  Pollution = excessive
   amounts of any undesirable
   material

              10
Management of High
Standards of living

    Toxic substance = a
     biological or chemical agent
     which interferes with normal
     metabolic processes




                11
Atmospheric Impacts

  Outdoor vs Indoor
  CO2, Global Warming
  VOC’s
  Acid Rain
  di-Benzo Furans
  Cd, Ni, NOx, O3, Pb, Rn-222
  Photochemical
  PCB’s
  Particulates



              12
Atmospheric Impacts

  Indoor Air Quality
  CO2, Rn-222
  Bacteria, Molds, Fungus
  Asbestos
  Particulates
  HVAC




              13
Aquatic Impacts

  Atmospheric Inputs
  Acid Rain
  Cd, Cu, Hg, Ni, Pb, Se, Zn
  Oil, Coal, PCB, PAH
  di-Benzp Furans
  Tributary Inputs
  As, Ba, Cd, Cr, Cu, Pb, Hg
  Pesticides
  Pathogens



              14
Aquatic Impacts

  Groundwater
  Ra-226
  Injection Wells
  Landfill Seepage
  Remediation
  Bioaccumulation




              15
Terrestrial Impacts

  Landfills (Solid Wastes)
  Non-hazardous Wastes
  Hazardous Wastes
  Agriculture
     • Pesticides
     • Nutrients
    Natural
     • Asbestos
     • Volcanoes
     • Actinide Ores


                    16
Other Community
Health Risks

  Accidents
  Social Interactions
     • Controlled
     • Uncontrolled
  Stress
  Diet
  Lifestyle
  Radiological
     • Non-Ionizing
     • Ionizing

                 17
Conclusions

  American society has one of
   highest standards of living in
   the world
  We are striving to do even
   better
  High standard has caused
   environmental problems
  Short term gains have not
   been weighed against long
   term consequences


               18
Conclusions - 2

  “Hidden Costs” often paid for
   in terms of community
   health.
  Barry Commoner:
     • Everything is related to
       everything else
     • Everything has to go
       somewhere
     • Nature knows best
     • There is no free lunch
