호남지역 신축 아파트의 휘발성유기화합물(VOCs) 실태 조사
A Survey of Volatile Organic Compounds(VOCs) in Newly Built Apartments at Honam Province
Abstract
This study was undertaken to investigate the concentration of VOCs from newly built apartments in threecities (Suncheon, Yeosu, and Gwangyang) of Honam province in Korea. VOCs were sampled using canisterand analyzed by GC/MSD. The result of the canister blank test showed that, most VOCs were not detectedwhen 5 ppb was cleaned once and 10 ppb was cleaned with two times. In case of the replicate alalysis tocheck for the precision of GC/MSD, RSD values were found to be excellent at 6%. The upper floor of Capartment (25 pyong) showed the highest concentration of TVOCs at 3,235 ㎍/㎥. The average concentrationof TVOCs was the highest in C apartment (25 pyong) as 1,833±1,217 ㎍/㎥. The average concentration ofTVOCs 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 concentrationof TVOCs was comparatively high in new apartment. Therefore, it is important to use low VOC emissionmaterials to reduce the emission concentration of VOCs from in new apartment. It is hence necessary thata scientific study is performed to secure clean indoor air quality.
