Passive sampler를 활용한 공원 내 냄새 원인 분석에 관한 연구
심녕주,김선태,이석준 한국냄새환경학회 2012 실내환경 및 냄새 학회지 Vol.11 No.1
This study was aimed to elucidate the cause of odor in a park, which was used for the landfill site about 20 years ago. For this purpose, VOCs concentration was measured using passive sampler at 10 sampling sites around a park for two times (spring and summer). The VOCs concentration measured in summer showed very low concentration and the relative VOCs ratio also showed no special patterns relating with other studies, which was caused to heavy rainfall during the sampling period. However, the relative ratio of toluene concentration of two sampling sites in spring appeared very high relating with other studies. It was thought that the high VOCs concentration in this park was caused not by landfill but by a neighboring painting materials company. 본 연구에서는 과거 20년 전 산업 폐기물 매립 후 지역 주민들에게서 냄새가 감지되고 있다고 보고된 A 공원에대해 그 원인을 규명하고자 총 10개의 지점에 passive sampler를 활용하여 대기 중 VOCs 농도를 봄과 여름에 2차에 걸쳐 측정하였다. 여름철 VOCs의 측정결과는 폭우의 영향 등으로 전반적으로 낮게 나타났으며, VOCs 성분비 또한 낮게 나타나 타 연구결과와 특이한 차이를 발견하지 못했다. 그러나, 봄철 측정결과의 toluene이 다른지점보다 높게 검출된 두 지점의 농도분포 비에서 toluene이 다른 매립지의 VOCs 성분비에 비해 매우 높게 나타나는 것으로 보아 공원에서의 악취는 폐기물 매립에 의한 것이 아니라 인근 페인트 공장에 인한 영향이 클 것으로 판단하였다.

According to the development of GC equipment, it has been possible to analyze the low level of ambient VOCs concentration. In this study, the limit of detection and the limit of quantitation were estimated for two GC equipments of the VOCs analysis, which would contribute to improve the quality of VOCs analysis results. The results of %RSD for ten standard solutes showed a great reproducibility in terms of detection time and detection area. The limit of detection and the limit of quantitation in SRI GC appeared to be 0.175 ppb and 0.583 ppb for benzene, and 0.223 ppb and 0.743 ppb for toluene, respectively. On the other hand, The limit of detection and the limit of quantitation in FISON GC appeared to be 0.149 ppb and 0.496 ppb for benzene, and 0.094 ppb and 0.313 ppb for toluene, respectively.
