국내 시중에 유통되어 음용되고 있는 먹는 샘물(생수) 30 종과 가정으로 공급되는 수돗물 9종중의 벤젠, 톨루엔, 에틸벤젠, 자일렌을 고체상미량추출법을 사용하여 정량하였다. 정지상은 100 μm PDMS fiber를 이용하였고, 실험조건은 실온에서, 교반시간 1200 RPM G, 흡착시간 4 분, 탈착시간 1 분이었다. 정량은 표준검량선법을 사용하였다. 평균검출한계는 벤젠 0.39 (±0.04) ng/mL, 톨루엔 0.08 (±0.04)ng/mL, 에틸벤젠 0.04 (±0.01) ng/mL, o-자일렌 0.05 (±0.02) ng/mL 이었다. 30 종의 먹는 샘물(생수)조사결과 벤젠과 o-자일렌은 모든 시료에서 검출되지 않았으며, 톨루엔의 경우는 11 개의 시료, 에틸벤젠은3 개의 시료에서 검출되었다. 검출된 물질의 각각의 농도범위는 0.24 (±0.09)~2.95 (±0.08) ng/mL,0.08 (±0.06)~0.93 (±0.10) ng/mL였다.
The amount of benzene, toluene, ethylbenzene, and o-xylene (BTEX) in 30 kinds of bottled waters purchased from market and 9 kinds of tap waters from home were determined using headspace solid phase microextraction (HS-SPME). The sample was stirred at 1200 RPM G for 4 min using a magnetic bar with 100μm PDMS as adsorbent for BTEX. Then it was desorbed from the fiber for 1 min at room temperature. Quantitation was achieved using standard calibration method. The limit of detection was determined as benzene 0.39 (±0.04)ng/mL, toluene 0.08 (±0.04) ng/mL, ethylbenzene 0.04 (±0.01) ng/mL, and o-xylene 0.05 (±0.02) ng/mL. Benzene and o-xylene were not detected in any samples, but toluene was detected in 11 samples, and ethylbenzene was detected just in 3 samples among 30 investigated bottled waters. The concentration range of investigated materials for toluene and o-xylene were 0.24 (±0.09)~2.95 (±0.08) ng/mL, 0.08 (±0.06)~0.93 (±0.10) ng/mL, respectively.
