In response to a request from the University of Georgia, an investigation was begun into health complains associated with indoor air quality at the Institute of Ecology (SIC-8221), Athens, Georgia. Episodes of poor indoor air quality were thought to be responsible for adverse health symptoms experienced by some of the occupants of the building. Previous indoor air quality investigations of the building were reviewed, and a site visit was conducted to review the heating, ventilation and air conditioning (HVAC) system, and conduct limited environmental monitoring. All the environmental parameters measured fell within the recommended standard limits. A review of the complaint log indicated that of the 98 total complaints, 34 were associated with an odor. Of the 49 questionnaires completed by workers, 36 (73%) indicated they had experienced either a health or a comfort problem associated with indoor air quality. Several potential sources of the problems were identified including an extreme negative pressure situation occurring in the laboratories and the potential for insufficient outside air to be provided to the building. Insulation linings in the HVAC system air handlers down stream from the air filters showed signs of deterioration and mold growth. The authors conclude that the indoor air quality related issues may be multifactorial in nature, and may involve entrainment of pollutants from outside sources.
