1,4-dioxane은 국제 암연구소에서 2B의 발암물질로 분류하고 있는 물질이다.지표수 중에 1,4-dioxane을 headspace gas chromatographic mass spectrometry에 의해 측정하였다. 시료 5 mL를 10 mL 헤드스페이스 vial에서 넣고 NaCl로 포화시킨 후 내부표준물질로 1,4-dioxane-d8 첨가한 후 <TEX>$90^{\circ}C$</TEX>에서 30분간 가열하였다. 위의 방법을 사용하여 금강 22개 지점에서 2012년 6월과 9월 시료 채취하여 분석한 결과 <TEX>$0.49-43.0{\mu}g/L$</TEX> (평균 <TEX>$2.0{\mu}g/L$</TEX>)의 범위로 약 30%의 빈도로 검출되었다.
1,4-Dioxane was classified as a Group 2B carcinogen by the International Agency for Research onCancer. The compound was measured in surface water with a headspace gas chromatographic mass spectrometricdetection. A 5 mL water sample was placed in a 10 mL headspace vial and saturated with NaCl, and thesolution was spiked with 1,4-dioxane-d8 as an internal standard and sealed with a cap. Water samples werecollected from twenty-two basins of Gum-River on June and September 2012, respectively. As a result, 1,4-dioxane was detected in the concentration range of 0.49-43.0 μg/L (mean 2.0 μg/L) in the frequency of about30% in surface water samples.
