초록

지표수 중에 GC-MS에 의한 페놀, 다환방향족탄화수소 및 농약류를 포함한 17 개 유해화합물을 동시에 분석하는 방법을 개발하였다. 1.0 L의 물 시료를 분액깔대기 안에 넣고 NaCl로 포화시킨 다음 40mL methylene chloride로 추출하였다. 이 방법은 1.0-10 ng/L 범위의 정량한계를 보였고 22% 이내의 정밀도를 보였다. 확립한 방법을 사용하여 35 지역의 금강 물 70 개 시료를 분석한 결과 유해화합물이 1.1-26,604 ng/L의 농도범위로 검출되었으며 측정값은 외국에서 확립한 준거치를 초과하는 값은 없었다. 이 측정방법은 지표수에서 유해화합물에 대한 국가모니터링사업에 사용할 때 효율적인 것으로 판단된다.

Abstract

A gas chromatography-mass spectrometric (GC-MS) method was developed for determining 17 hazard compounds containing phenols, polycyclic aromatic hydrocarbons and pesticides in surface water. A 1.0 L surface water sample was placed in a separatory funnel and saturated with NaCl, and the solution was extracted with 40 mL of methylene chloride. Under the established condition, the lowest quantification limit was 1.0-10 ng/L and the relative standard deviations were less than 22%. The method was used to analyze 70 surface water samples collected from 35 regions in Gum-River. The samples revealed the compounds concentrations in the range of 1.1-26,604 ng/L. Maximum concentrations of compounds detected were not exceeded guidelines established in other countries. The developed method may be valuable for monitoring hazards in water.
