Title: Comparison of DI-SPME-GC-MS and SPE-GC-MS with derivatization for analysis of steroid hormones in river water

Abstract: In this study two extraction methods were performed for analysis of estrone and beta-estradiol in  wastewater effluent and Somes River water: solid-phase microextraction (SPME) and solid phase extraction (SPE), both followed by gas chromatography - mass spectrometry (GC-MS). The target compounds were detected in water samples collected downstream of municipal sewage treatment plant of Cluj-Napoca, Romania. The results obtained by SPME and SPE methods for analyzed samples were of the same order of magnitude.
