Indoor Air Quality Measurements in 38 Pacific Northwest Commercial Buildings
A Bonneville Power Administration-funded study monitored ventilation rates and a variety of indoor air pollutants in 38 Pacific Northwest commercial buildings. The buildings ranged in age from 6 months to 90 years, in size from 864 to 34,280 m sup 2 , and occupancy from 25 to 2500 people. Building average formaldehyde (HCHO) concentrations were below the 20 ppB detection limit in 48% of the buildings. Nitrogen dioxide (NO sub 2 ) concentration averages ranged from 5 ppB to 43 ppB and were lower than outdoor concentrations in 8 of 13 buildings. At only one site, an elementary school classroom, did carbon dioxide (CO sub 2 ) exceed 1000 ppM. Radon (Rn) levels were elevated in one building with an average concentration of 7.4 pCiL sup -1 . Respirable particles (RSP) concentrations in smoking areas in 32 buildings had a geometric mean of 44 mu g m sup -3 and ranged up to 308 mu g m sup -3 at one site. In non-smoking areas the geometric mean RSP was 15 mu g m sup -3 . Outside air ventilation rates did not appear to be the single dominant parameter in determining indoor pollutant concentrations. Measured pollutant concentrations in 2 ''complaint'' buildings were below accepted guidelines. The cause of the complaints was not identified. (ERA citation 12:005180)
