초록

생물시료에 존재하는 휘발성 유기화합물 중 n-butylbenzene과 1,2-dibromo-3-chloropropane (DBCP)를 기체크로마토그래피/질량분석기-선택이온검색법에 의해 수행하였다. 시료 중 휘발성 유기화합물은 <TEX>$100{\mu}m$</TEX> polydimethyl siloxane (PDMS) fiber를 사용하여 headspace solid phase microextractio (SPME) 및 purge & trap 방법에 의해 추출 및 비교하였다. SPME에 의한 회수율은 n-butylbenzene의 경우 85.8%, DBCP의 경우 92.4%로 나타났고 검출한계는 각각 <TEX>$0.15{\mu}g/kg$</TEX>, <TEX>$0.05{\mu}g/kg$</TEX>로 나타났다. 반면, purge & trap의 경우 회수율은 n-butylbenzene의 경우 115.2%, DBCP의 경우는 80.9%로 나타났고 검출한계는 각각 <TEX>$0.04{\mu}g/kg$</TEX> 및 <TEX>$0.70{\mu}g/kg$</TEX>로 나타나 두 방법에 있어 국내에서 규제하는 검출한계측면에서 큰 차이는 없었다.

Abstract

The analysis of n-butylbenzene and 1,2-dibromo-3-chloropropane (DBCP) as volatile organic compounds in biota samples was performed by gas chromatography/mass spectrometry-selected ion monitoring mode. The target compounds, n-butylbenzene and DBCP, in biota samples were extracted by headspace solid phase microextraction (SPME) with <TEX>$100{\mu}m$</TEX> polydimethyl siloxane (PDMS) fiber and purge & trap method. The extraction recoveries of these compounds obtained by SPME was 85.8% for n-butylbenzene and 92.4% for DBCP, respectively. Each value of method detection limit were <TEX>$0.15{\mu}g/kg$</TEX> and <TEX>$0.05{\mu}g/kg$</TEX>, respectively. While in the case of purge & trap method, the extraction recovery was 115.2% for n-butylbenzene, 80.9% for DBCP and method detection limit were <TEX>$0.04{\mu}g/kg$</TEX> and <TEX>$0.70{\mu}g/kg$</TEX>, respectively. The extraction yields and detection limits of these compounds obtained by purge & trap were equivalent to those by SPME.
