        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.

        Banana에 존재할 수 있는 carbamate 농약류, 유기염소제 및 유기인제 농약을 GC/MSD에 의해 동시에 분석할 수 있는 방법을 연구하였다. 이를 위해서 일반적으로 carbamate 분석에 이용되는 HPLC 대신에 GC를 이용하기 위해 carbamate 농약류의 -NH group H를 모두 열안전성이 좋은 trifluoroacetyl group으로 치환시켰다. 또한, 시중에서 유통되는 9종의 sample을 분석한 결과 carbamate 농약류, 유기염소제 및 유기인제 등 8종의 잔류농약은 검출되지 않았다.
