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.
