  1. 1. Something’s in the Air The Factors for Creating Health Supporting Indoor Environments Institute for Bau-Biologie & Ecology A Florida 501 (c) 3 educational non-profit Presented by: Larry Gust, Gust Environmental, Ventura, CA www.GustEnviro.com • 805-644-2008
  2. 2. Why Is This An Issue? You breathe 1500 quarts of air a day. One of the Top Five Health Risks (EPA) First on the List of Environmental Cancer Risks (EPA) Home air: 6-10 times more polluted than city (EPA) 90% of our time is spent indoors where 60+% of offices are polluted and homes are worse (tighter).
  3. 3. Why Is This An Issue? Allergists – 50% of Illness caused or worsened by indoor pollution  Fifty years ago 1 in 30 had allergies  Ten years ago 1 in 3 had allergies  Today 1 in 2.5 have allergies Asthma has doubled since 1980 – heavily kids MCS has grown to about 18% of the population
  4. 4. Sick Building Syndrome (SBS) EPA: 65% of office buildings Acute health & comfort effects linked to time in bldg. No specific cause can be identified Symptoms abate outside of building
  5. 5. Sick Building Syndrome (SBS) Classed as SBS if 20% of population is affected Social security admin union survey (1993):  Fatigue – 39%  Sneezing / coughing – 45%  Sinus / nasal congestion – 49%  Eye, nose, throat irritation – 38%
  6. 6. Building Induced Illness Conditions induced by building conditions Symptoms do not abate outside building
  7. 7. The Rain & Barrel & Total Load
  8. 8. Manipulating The Barrel to Reduce Loading Clean up your diet / habits Clean up your water Clean up your home / office
  9. 9. Manipulate the Politicians Chernoble radiation reaches Canada and NY in 24 hours Pesticide sprayed in South Africa reaches Key West in 5 days Pesticide sprayed in Texas reaches Cincinnati in 36 hours Indoor air is outdoor air PLUS …
  10. 10. Sources of Indoor Pollutants 1. Human activity 2. Combustion products 3. Biological agents 4. Radon 5. Pesticides 6. Volatile organic compounds 7. Particulates 8. Electromagnetic energies (Another Lecture)
  11. 11. Pollutant Concentration Factors Number of sources and volume Rate of removal
  12. 12. Removal Strategies Source control:  Exclusion  Capture at source Pollutant removal (dilution):  Air changes per hour (bldg. tightness)  Air cleaning
  13. 13. Removal Strategies Ventilation is for People For all pollutants except people it is best to apply source control
  14. 14. Pollutant Source #1  Human Activity  Carbon dioxide, water vapor, odors  Handled by dilution & removal (trapping)
  15. 15. Pollutant Source #2  Combustion Products • Carbon monoxide, dioxide and by-products • Source removal Keep sources out of living space
  16. 16. Combustion Products  Exclusion & Source Capture  Fireplace – external air source, tight doors  Furnace, water heater – Use closed system  Range exhaust hood– Vent outside  Built-in oven– Vent outside  Monitoring  Carbon monoxide monitor/alarm
  17. 17. Pollutant Source #3 Biological Agents: Mites, Bacteria, Virus, Fungi Symptoms  Infectious disease  Malaise  Exacerbation of asthma  Fatigue  Runny nose  Chest tightness  Conjunctive inflammation  Cough  Recurrent fever  Dermatitis  Diarrhea  Headache  Breathing Difficulty
  18. 18. Mold: Leviticus 14: 37 - 47 … And you shall examine the house for plague; and if the plague is on the walls of the house with ingrained streaks, greenish or reddish, which appear to be deep in the walls, then close the house up for seven days. If you return and the plague has spread, then remove the stones and walls and the dust they scrape off. Now if the plague comes back after he has taken away the stones and plaster, then the house indeed has the plague. And he shall break down the house, its stones and timbers and all the plaster of the house, and he shall carry them outside the city to an unclean place. And he who is inside the house shall wash his clothes …
  19. 19. Causes of Fungal Reactions: Allergenic cell wall proteins Microbial Volatile Organic Compounds Fungal generated Mycotoxins
  20. 20. Conditions for Fungi Growth Food source Spores Moisture (as low as 70% RH for some)
  21. 21. Moisture Sources Moisture producing appliances & activities Foundation capillary action Structural water leaks Condensation on cold surfaces
  22. 22. Surface Temperature Control Dew Point depends on % RH and Surface Temperature Surface Temperature depends on  Insulation from cold temperatures  Correct installation
  23. 23. Whole House Humidity Control Ultra Aire by Therma-stor
  24. 24. Flooding- Correct Clean Up Stop water at the source Remove Porous Materials Immediately Dry out remaining materials within 36 -48 hours After this mold quickly becomes a big problem • Use a Certified Restorer from • American Indoor Air Quality Council (AmIAQC) • Institution of Inspection, Cleaning & Restoration Certification (IICRC) Sewage is another issue • Already contaminated with virus, bacteria & parasites • Biocides are used a several steps of remediation
  25. 25. Testing for Mold Air Samples:  Spore Trap  Culturable Surface Samples:  Tape lift  Culturable
  26. 26. Another Fungus. . . Sudden Infant Death Syndrome (SIDS)  Caused by fungus that grows in the bed and produces a neurotoxin gas.  Caused by use of flame resistant mattresses.  More danger from hand me down mattresses because the fungus grows stronger over time.  Can be avoided by simply placing a plastic bag over mattress.
  27. 27. Sources of Indoor Pollutants Our Lecture Roadmap Human activity Combustion products Biological agents Radon Pesticides Volatile organic compounds Particulates
  28. 28. Pollutant Source #4 Radon • Colorless, odorless, radioactive gas • Found in bedrock & soil from decay of radium 226 • Radon half life is 3.8 days • Decay products are solid particles that live minutes • Decay energy is dangerous to lung tissue • The lungs take in radioactive particles riding on dust • Second leading cause of lung cancer after smoking
  29. 29. Radon Enters via Cracks in Foundation Parts Basements are the main problem Seal foundation cracks, penetrations, joints Use Sub-slab suction Screening:  Radon kit (Home Depot)
  30. 30. Pollutant Source #5 Pesticides 4 billion applications per year 85% of households store 3 to 4 pounds 20,000 household pesticide products 140,000 reported exposures in 1993, 93% home use, 50% children under six
  31. 31. Types of Pesticides Chlorinated (chlordane, lindane, heptachlor) Carbamate (carbaryl) anti-cholinesterase Organophosphate (chlorpyrifos) anti-cholinesterase Newer pesticides have lower acute toxicity Little research into subtle effects  Immune function issues  Cognitive damage 300 active (controlled) ingredients
  32. 32. Pesticides Continued 1700 inert (uncontrolled) ingredients  Manufacture decides with FDA agreement  Some product’s inerts are actives in others  Toluene, xylene – central nervous system depressant  Ethyl benzene – know carcinogen
  33. 33. Pesticide Exposure Hampers Development in Children • Study: Sonora Technological Institute, Mexico • Children ages 4-5 from Sonora’s Yaqui Valley 45 pesticide applications times per crop cycle • Children ages 4-5 from nearby foothills Pesticide used is avoided • Pesticide exposure impairs cognitive development
  34. 34. Disturbing Development:
  35. 35. Pesticide Facts: Significant source of indoor pollution (esp. Southern climates) Binds strongly to synthetic materials Carpeting is contaminated even after repeated cleaning
  36. 36. Pesticide Facts: Binds to dust which can float in the air Remediation is partial at best & may not be enough for the sensitive Remediation of older chlorinated pesticides is probably impossible
  37. 37. Remediation Approaches Discard exposed synthetics Steam clean remaining items with minimum 150 degrees steam Clean all hard surfaces with vinegar, detergent and water Reduce air concentration with carbon/zeolite filtration Get additional info from HEAL 404-248-1898, http://members.aol.com/HEALNatnl
