A new technique was proposed for the determination of alkylphenols, chlorophenols and bisphenol A in korean aquatic biological samples. The alkylphenols, chlorophenols and bisphenol A in korean aquatic biological samples were extracted with acetonitrile and then acetonitrile layer was refrigerated at $-60^{\circ}C$ for 2 hours(freezing filtration method). Also, solid-phase extraction(SPE) was used to XAD-4 and subsequent conversion to isobutoxycarbonyl(isoBOC) or tert-butyldimethylsilyl(TBDMS) derivatives for sensitive analysis with gas chromatography/mass spectrometry-selected ion monitoring(GC/MS-SIM) mode. For isoBOC derivatization and TBDMS derivatization the recoveries were $70.1\sim150.6%$ and $93.8\sim108.3%$, the method detection limit(MDLs) of bisphenol A for SIM were $0.062{\mu}g/kg$ and $0.010{\mu}g/kg$, and the SIM respectively. When these methods were applied to korean aquatic biological samples, the concentrations of the 11 phenolic EDCs were $0.675\sim1.970{\mu}g/kg$.
