Abstract

Geosmin and 2-methylisoborneol (2-MIB) are volatile organic compounds responsible for the majority of unpleasant taste and odor events in drinking water. Geosmin and 2-MIB are byproducts of blue-green algae (cyanobacteria) with musty and earthy odors. These compounds have odor threshold concentration at ng/L levels. It is needed to develop a sensitive method for determination of geosmin and 2-MIB to control the quality of drinking water. In this study, geosmin and 2-MIB in water samples were determined by gas chromatography-mass spectrometry (GC-MS) with headspace-solid phase microextraction (HS-SMPE). The detection limits of this method were 1.072 ng/L and 1.021 ng/L for geosmin and 2-MIB, respectively. Good accuracy and precision was also obtained by this method. Concentrations of the two compounds were measured in raw waters from Nakdong River in the cyanobacterial blooming season. Water bloom formed by cyanobacteria has been occurred currently in Nakdong River. It is needed to investigate the concentrations of geosmin and 2-MIB to control the quality of drinking water from Nakdong River. Both geosmin and 2-MIB were detected in raw waters from Nakdong River at concentrations ranging from 4 to 24 ng/L and 6 to 16 ng/L, respectively.

Geosmin과 2-methyl isoborneol (2-MIB)는 먹는물에서 불쾌한 맛과 냄새를 일으키는 대표적인 물질이며, 남조류의 대사산물로 흙 냄새나 곰팡이 냄새를 내는 것으로 알려져 있다. 이들 물질의 최소감지 농도는 수 ng/L 수준으로, 먹는물의 질을 관리하기 위해서는 극미량까지 분석할 수 있는 분석방법이 요구된다. 본 연구에서는 물시료 중의 geosmin과 2-MIB를 headspace-solid phase microextraction (HS-SMPE) 법과 기체크로마토그래프/질량분석기 (gas chromatograph/mass spectrometer, GC/MS)를 이용하여 분석하였다. 방법검출한계는 geosmin과 2-MIB에 대하여 각각 1.072 ng/L, 1.021 ng/L 값을 구할 수 있었으며, 정확도와 정밀도에서도 좋은 결과를 얻을 수 있었다. 최근 낙동강에서는 남조류에 의한 수화현상이 종종 발생하고 있어, 낙동강을 상수원수로 하는 먹는물의 안정성을 확보하기 위하여 geosmin과 2-MIB의 농도를 조사할 필요성이 대두되고 있다. 남조류가 번성한 시기에 낙동강 원수에 대하여 geosmin과 2-MIB의 농도를 조사한 결과, 각각 4~24 ng/L, 6~16 ng/L의 농도로 검출되었다.
