Sample preparation was examined with conventional extraction methods, such as solid-phase extraction (SPE) and liquid-liquid extraction (LLE), and their efficiency was compared with validation results, including linearity of calibration curve, method detection limit (MDL), limit of quantification (LOQ), accuracy, and precision. METHODS AND RESULTS: The BPs (bisphenol A, BPA; bisphenol B, BPB; bisphenol C, BPC; bisphenol E, BPE; bisphenol F, BPF; bisphenol S, BPS) were analyzed using GC-MS. The range of MDLs by SPE and LLE methods was *Corresponding author: Tae-Woo Kang Phone: +82-62-970-3990; Fax: +82-62-970-3999; E-mail: kangtw@korea.kr *Co-Corresponding author: Jae-Han Shim Phone: +82-62-530-2135; Fax: +82-62-530-0219; E-mail: jhshim@jnu.ac.kr 0.0005 0.0234 g/l and 0.0037 0.2034 g/l, and that of LOQs was 0.0015 0.0744 g/l and 0.0117 0.6477 g/l, respectively. The calibration curve obtained from standard solution of 0.004 4.0 g/l (SPE) and 0.016 16 g/l (LLE) showed good linearity with r 2 value of 0.9969 over. Accuracy was 93.2 108% and 97.4 120%, and precision was 1.7 4.6% and 0.7 6.5%, respectively. The values of MDL and LOQ resulted from the SPE method were higher than those from the LLE method, particularly those values of BPA were highest among the BPs. Based on the results, the SPE method was applied to determine the BPs in river water samples. Water samples were collected from mainstream, tributary and sewage wastewater treatment plants (SWTPs) in the Yeongsan river basin. The concentrationofbpb,bpc,bpe,bpfandbpswerenot detected in all sites, whereas BPA was ranged 0.0095 0.2583 g/l, which was 0.0166 0.0810 g/l for mainstreams, 0.0095 0.2583 g/l for tributaries, 0.0352 0.1217 g/l for SWTPs. CONCLUSION: From these results, the SPE method was very effective for the simultaneous determination of BPs in river water samples using GC-MS. We provided that it is a convenient, reliable and sensitive method enough to 154
