This study was undertaken to investigate the concentration of VOCs from newly built apartments in three cities (Suncheon, Yeosu, and Gwangyang) of Honam province in Korea. VOCs were sampled using canister and analyzed by GC/MSD. The result of the canister blank test showed that, most VOCs were not detected when 5 ppb was cleaned once and 10 ppb was cleaned with two times. In case of the replicate alalysis to check for the precision of GC/MSD, RSD values were found to be excellent at 6%. The upper floor of C apartment (25 pyong) showed the highest concentration of TVOCs at 3,235 ㎍/㎥. The average concentration of TVOCs was the highest in C apartment (25 pyong) as 1,833±1,217 ㎍/㎥. The average concentration of TVOCs in K (52 pyong) and S apartment (16 pyong) were 1,820±1,035 ㎍/㎥ and 498±71 ㎍/㎥, respectively. The I/O ratio of TVOCs were 8.99∼35.90 (mean : 25.99), 11.51∼35.43 (mean : 20.07) and 6.03∼7.90 (mean : 6.92) in K, C and S apartment, respectively. From these results, it is believed that the concentration of TVOCs was comparatively high in new apartment. Therefore, it is important to use low VOC emission materials to reduce the emission concentration of VOCs from in new apartment. It is hence necessary that a scientific study is performed to secure clean indoor air quality.
