Concentrations of formaldehyde, acetaldehyde, acetone and acrolein were measured, in addition to dust concentrations, at smoking rooms, smoking corners of the stations and several other places where smoking was permitted. Dust concentration was 0.439 mg/m3, formaldehyde concentration 46.0 μg/m3 and acetaldehyde concentration 101.7 μg/m3 at smoking room A where a ventilation fan was in operation. Dust concentration was 0.288 mg/m3, formaldehyde concentration 71.6 μg/m3 and acetaldehyde concentration 121.7 μg/m3 at smoking room B where an air purifier was in operation. Ratios of formaldehyde, acetaldehyde, acetone and acrolein concentrations to SPM concentration at smoking room A were 0.10, 0.18, 0.10 and 0.013, respectively. Ratios at smoking room B higher than those at smoking room A because although the air purifier could remove dust, it could not completely remove formaldehyde and acetaldehyde.

To test the idea that concentration of air pollutants such as NOx, CO and SPM is significantly increased in enclosed spaces frequented by automobiles, an investigation of air pollution at a 52-space underground parking lot was carried out. Average concentrations of NO2, NO, CO, SPM and HCHO were 103ppb, 221ppb, 8.7ppm, 20.7μg/m3 and 18.0ppb respectively. Concentrations of NOx and CO were significantly higher than outdoors. Correlation between NOx and CO concentrations and the number of parking cars was not high, because the automobile sources of the pollutants were immediately present.
