A survey of indoor air quality in twenty-nine anchorage residences

During the winter of 1987-88, 29 Anchorage residents who contacted various agencies with indoor air pollution inquiries had their homes inspected and monitored for several indoor air pollutants. A survey form was completed during an interview with occupants of each residence visited. Data were collected on house characteristics and behavior of occupants. The mean nitrogen dioxide (NO2) concentration for residences with measurable amounts of this gas was .024 ppm, while the mean formaldehyde (HCHO) concentration with measurable levels was .037 ppm. Residences with gas cooking ranges had mean NO2 concentrations twice as high as those with electric ranges. Several residences had NO2 concentrations exceeding recommended standards.
