Summary: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.
