The aim of this study is to analyze the distribution of particulate matters including PM<sub>2.5</sub> which is known for severe adverse health effect than PM<sub>10</sub> in public facilities. The total 40 public buildings are investigated in this study and they are classified into 11 sub-groups as follows : child-care centers, medical centers, libraries, museums, bus terminals, ports, airports, railway terminals, subway stations, large-scale stores, and indoor parking lots. The mean concentration of PM<sub>10</sub> was 38.6㎍/㎥ and that of PM<sub>10</sub> in all studied facilities were lower than the Ministry of Environment's control standards. The average concentration of PM<sub>2.5</sub> was 27.2㎍/㎥ and that of PM<sub>2.5</sub> in 18 facilities were exceed the guideline of WHO (24h average value : 25㎍/㎥). The subway stations had the highest indoor level of particulate matters and the waiting area in bus terminals, railway terminals, indoor parking lots had followed in order. When comparing mean value of I/O ratio of PM<sub>10</sub>, the only I/O ratio of subway stations were greater than one. In the case of PM<sub>2.5</sub>, however, the average concentrations of PM<sub>2.5</sub> in indoors of subway stations, bus terminals, and indoor parking lots were higher than those of PM<sub>2.5</sub> in outdoors. The mean concentration of PM<sub>10</sub> and PM<sub>2.5</sub> were gradually increased between 6 A.M and 10 A.M and after 6 P.M in most of target buildings with increasing the number of users in thest facilities.
