영문 초록

In activity areas of subway workers and passengers in Seoul metropolitan subway lines 1-4, mean concentrations of airborne bacteria were relatively higher in workers bedroom and station precinct whereas concentrations of particulate matters, PM10 and PM2.5, were relatively higher in platform, inside train and driver s seat as compared with other activity areas. This result indicates that little correlation between airborne bacteria and particulate matters was found, which assumed that most airborne particulate matters distributed in subway consisted of mainly inorganic dust like a metal particles. Mean concentrations of PM10 and PM2.5 in station precinct and platform exceeded the threshold limit value (PM10 : 150 g/m3, PM2.5 : 65 g/m3) but those in station office and ticket office were below it. The genera identified in all the activity areas of subway over 5% detection rate were Staphylococcus, Micrococcus, Bacillus and Corynebacterium, of which Staphylococcus and Micrococcus covered over 50% of total airborne bacteria and were considered as predominant genera distributed in subway.
