Linda Nussbaumer on Indoor Environment

  1. 1. Indoor Air Pollution: Health Effects & Challenges Linda L. Nussbaumer, PhD Professor of Interior Design South Dakota State University Plain Green Conference 2008 2008 25 September
  2. 2. Indoor Air Pollution: Health Effects & Challenges Causes of Indoor Air Pollution Health Affects from Indoor Air Pollution Challenges for designers Challenges for individuals with MCS Conclusions 2008 25 September
  3. 3. Cause of Indoor Air Pollution
  4. 4. Categories of indoor air pollutants
  5. 5. Sources of Indoor Air Pollution
  6. 6. Affects from Indoor Air Pollution Sick Building Syndrome (SBS) ◦ An array of symptoms that affect some of a building’s occupants while they are in the building and that diminish or go away when they leave the building, yet “cannot be traced to specific pollutants or sources within the building”. Chronic Illness ◦ Asthma ◦ Multiple Chemical Sensitivity ◦ Other SBS definition from EPA, 2003
  7. 7. Affects from Indoor Air Pollution Multiple Chemical Sensitivity or MCS ◦ “A condition in which a person reports sensitivity or intolerance . . . to a number of chemicals and other irritants at very low concentrations” EPA, 2003
  8. 8. Criteria for diagnosis of MCS 1. The illness must be chronic condition 2. Symptoms recur reproducibly 3. Symptoms occur in response to low levels of exposure 4. Exposure is to multiple unrelated chemicals 5. Symptoms improve or resolve when incitants are removed 6. Multiple organ systems are affected Bartha, et al, 1999
  9. 9. Symptoms triggered by Exposure
  10. 10. Locations of Exposures Poorly ventilated buildings Communities with high air or water pollution Exposure in unique situations Air-tight buildings with poor IAQ
  11. 11. Synergistic Reactions One chemical mixing with another chemical ◦ Creates a volatile reaction within the body  Alcohol and barbiturates  Tobacco smoke & radon gas Bower, 2000
  12. 12. Problems diagnosing MCS
  13. 13. Problems with Indoor Air (IAQ) EPA, 1995
  14. 14. Challenges for designers
  15. 15. Challenges for individuals with MCS Where are the problems/challenges? ◦ Live ◦ Work ◦ Play ◦ Shop
  16. 16. Conclusions
  17. 17. Thank you Linda L. Nussbaumer, PhD Professor of Interior Design South Dakota State University Linda.Nussbaumer@sdstate.edu
