Abstract

Abstract : This study was conducted to obtain the basic data of two common odorants—geosmin and 2-methylisoborneol (GSM and 2-MIB)—in environmental water. More specifically, the headspace solid-phase microextraction coupled to gas chromatography mass spectrometry (HS-SPME/GC-MS) was applied to determine the levels of GSM and 2-MIB in water samples, and the samples were collected depending on water sources, conventional treatment processes, and seasons. The significant difference was shown for the 2-MIB levels of source water P < 0.05, the concentrations of GSM and 2-MIB decreased significantly as treatment process of tap water moved forward ( P < 0.0001 ), and the significant differences for the levels of GSM and 2-MIB were observed among three sampling periods ( P < 0.01 ) . The levels of GSM and 2-MIB in all water samples were lower than 10 ng L −1, the odor threshold concentration (OTC), and the conventional treatment process plays a significant role in removing odorants in tap water.
