AbstractResults of air quality measurements are presented for a group of low-leakage houses located in Saskatoon, Saskatchewan. A total of 46 houses were tested for formaldehyde, nitrogen dioxide, radon, and humidity levels. The median level of formaldehyde was 0.09 ppm, slightly lower than the guideline of 0.1 ppm. Elevated levels of formaldehyde(> or = 0.1 ppm) were found in 18 of 46 houses. The median level of radon was 3.0 picocuries/litre, slightly lower than the guideline of 4 pCi/L. Elevated levels of radon (> or = 4 pCi/L) were found in 12 out of 44 houses. The median level of nitrogen dioxide was 4.6 ppb, considerably lower than the guideline of 50 ppb. No houses were found with elevated nitrogen dioxide levels (> or = 50 ppb).
