In this study, the characteristic of the facilities and indoor environment for the senior citizens nursing facilities of Kyeonggki and Seoul-total 30 facilities;10 facilities in Seoul and 20 facilities in Kyeonggki from January to December in 2007. In the result of surveying indoor and outdoor pollution degree of 30 senior citizens nursing facilities, the average geometric concentration of indoor and outdoor TVOCs were 264.11 ㎍/㎥ and 162.63 ㎍/㎥, respectively. On the other hand, the average geometric concentration of indoor and outdoor HCHO were 22.76 ㎍/㎥ and 9.55 ㎍/㎥, respectively. The concentration ratio of indoor and outdoor air pollutants were 1.21, 1.23, 1.62 and 2.38 for benzene, toluene, TVOCs and HCHO, respectively. The concentrations of toluene, TVOCs and HCHO were 31.40 ㎍/㎥, 274.30 ㎍/㎥ and 24.17 ㎍/㎥ in the building constructed after 2000. On the other hand, The concentrations of toluene, TVOCs and HCHO were 27.99 ㎍/㎥, 248.54 ㎍/㎥ and 20.48 ㎍/㎥ in the building constructed before 2000. As the constructed year was not late, low concentration was indicated. In the facilities using carpet or not, the concentration of toluene, TVOCs and HCHO were 50.50 ㎍/㎥, 342.73 ㎍/㎥ and 32.94 ㎍/㎥, respectively, in the facilities using carpet. On the other hand, the concentration of toluene, TVOCs and HCHO were 29.35 ㎍/㎥, 261.41 ㎍/㎥ and 22.40 ㎍/㎥, respectively, in the facilities using no carpet. The concentrations were presented higher in the facilities where carpet exits.
