The most principal approach to improve indoor air quality(IAQ) of subway was to examine the fine particulate(PM-10) from the emission sources. Therefore, this study was carried on the investigation the fine particulate for comparison with the removal efficiency of PM-10 in divided the PSD(Platform Screen Door) and Non-PSD subway station from July, 2007 to May 2008. In the monitoring results, the range of PM-10 concentration of Non-PSD station was 44.6∼116.5㎍/㎥ and the range of PM-10 concentration of PSD station was 23.9∼81.1㎍/㎥. And then the range of PM-2.5 concentration of Non-PSD station was 17.4-56.6㎍/㎥, and then the range of PM-2.5 concentration of PSD station was 17.9∼34.4㎍/㎥. In comparison with the results of the PSD and Non-PSD subway station, we found that the PM-10 removal efficiency of PSD was 30-40%. In conclusion, the PSD will be applied the effective facilities of decreasing PM-10 in subway station in Korea.
