Indoor Air QualityBuilding Anatomies & Their Importance
• 78.7 / 70 / 50 / 26 / 5 (varies by country)
• Higher levels of many toxic chemicals
• Dominates lifetime exposure to toxic chemicals
• Huge impact on fetuses, newborns
• IAQ affects productivity
• Buildings impact the natural environment
Importance of Buildings & IAQ
“If truckloads of dust with the same concentration of toxic chemicals as is found in most carpets were deposited outside, these locations would be considered hazardous waste dumps”
Ott & Roberts, “Everyday Exposure to Toxic Pollutants,” Scientific American, 1998
