    • built-damns and indoor air pollution
  2. five leading causes death
    • accidents
    • homicide
    • suicide
    • cancer
    • heart
  3. assess physical environment5
    • risk
    • public health
    • ecological
    • interaction
    • systems 
  4. risk assessment***
    potential hazard
  5. public health assessment***

    ex.
    expands on risk but has data about entire population

    ex. CASPER, first responders, respiratory equipment needed
  6. ecological assessment***
    affect plants and animals
  7. interaction analysis***
    • neccessary to take into account of two exposures like
    • additive: independent
    • multiplicative: blended
  8. systems analysis***
    interconnections btw larger networks like airway transportation/hole in ozone layer/interventions of motor safety
  9. 4 step risk assessment basic def
    measure the potential impact of known hazards
  10. 4 step risk assessment***
    • hazard identification-what? 
    • [[dose response assessment-diff exposure
    • exposure assessment-how much for how long]]
    • risk characterization-extra risk like eating contaminated fish
  11. CASPER***
    • Community
    • ASsessment
    • for Public Health 
    • Emergency 
    • Response
  12. first responders
    • dehydration
    • volatile 
    • chronic condition among workers
  13. hazard identificaiton
    benzene causes leukemia 
  14. dose response
    different exposures>>kind of prob
  15. exposure assessment 
    how much are ppl exposed to
  16. risk characterization
    extra risk 
  17. included environmental factors8
    • pollution of air
    • UV
    • noise
    • occupational risks
    • built
    • ag methods

  21. Improvements 3

    Recognized risks of toxins
    Form EPA
    Recognize on chronic diseases 
    • Carson of DDT
    • ----
    • like air pollution, lack of physical activity, occupational risks
  22. natural risk factors
    • climate
    • carcinogens
    • air quality
  23. built risk factors
    • carcinogens
    • occupational risks
    • safety risks 
    • no physical activity 
  24. EPA 
    environmental protection agency: gives grants, study, sponsor, teach, publish, enforce
  25. name 4 human health risk assessment
    • hazard identification
    • dose response assessment
    • exposure assessment 
    • risk characterization 
  26. case of lead
    now found in 
    physiology
    toxicity of acute vs. chronic 
    • use to be jewelry; now gas 
    • found in soil, plant, air 
    • to kidneys, bones, teeth/can be excreted 
    • acute: gastro/nervous vs chronic: anemia, kidney, reproductive
