Recently, concern about Sick House Syndrome (SHS) has been increased in Korea. And it is suspected that formaldehyde (HCHO) and volatile organic compounds (VOCs) are major factors for SHS. This study was surveyed the indoor air quality in new apartments in Korea. The HCHO and VOCs were measured at 90 sites and analysed by HPLC-UV and GC/MS, respectively. The range of HCHO concentrations at 90 sites were 9.39∼248.78㎍/㎥ and the mean value 105.41㎍/㎥ and the concentrations of HCHO at 42 sites (46.7%) exceeded the indoor air quality guideline (100㎍/㎥) in Japan. Among the 4 VOCs, toluene concentrations were the highest and the mean value 127.33㎍/㎥ and that concentrations at 12 sites (13.8%) were exceeded the indoor air quality guideline (260㎍/㎥) in Japan. There was a tendency which the longer the movement and measurement period is, the more the pollutants concentration is decreased. HCHO and VOCs concentrations of domestic results was similar to Japan"s survey results in 2000.

고속원소충격질량분석법을 이용하여 thromboxane $B_2$의 극미량분석법을 개발하였다. static FAB mode에서 decosanoic acid를 내부표준물로 이용하여 검출한계 5ng의 분석법을 확립하였고, CF-FAB mode에서 고안한 시료도입장치를 사용하여 thromboxane $B_2$의 측정감도, 재현성 등 정량분석에 미치는 용매조성, 용매의 유속 등 분석파라미터들을 조사하였다. CF-FAB mode에서 0.75% glycerol(in EtOH, v/v)을 eluent 용매로, 유속을 $3.7{\mu}l/min.$로 하여 분석조건을 최적화하고 TIC법과 SIM 검출법을 이용하여 정량한계 각각 500pg 및 10pg인 극미량분석법을 확립하였다. Analytical methods of thromboxane $B_2(TXB_2)$ using various techniques of Fast Atom Bombardment mass spectrometry (FAB MS) were studied, static FAB condition was investigated to obtain linear response curve using docosanoic acid as a internal standard. For maximum sensitivity, a continuos-flow(CF-) FAB MS by selected-ion monitoring(SIM) with devised sample introduction system, has been developed to quantiate thromboxane $B_2$ in biological sample. Instrumental parameters affecting sensitivity, reproducibility has been studied. The method has been optimized with respect to the eluent, 0.75% glycerol(in EtOH v/v) and flow rate of $3.7{\mu}l/min.$ Under the condition, detection limits were below 10pg in SIM mode and a good linear relationship between dose and response was achieved.
