Abstract

The most common 8 phthalic acid esters (PAEs) and adipate in sediment were measured 5 times from 1999 to 2001 at 11 sites of river in Korea. Ultrasonication extraction with dichloromethane was done for extraction of the sediment. After concentration GC/MS-SIM analysis was performed. Three compounds (DEP, DBP and DEHP) among eight phthalic acid esters were detected from the sediment samples, and the other PAEs were not detected in any samples. DEHP (27.3~63.6%) was detected with higher frequency than any other compounds for sediment samples. And this compound had shown the highest average concentration (81.7~427.6 ng/g).

환경시료 중에서 가장 일반적으로 검출되는 8종의 프탈산 에스테르 및 아디피산을 1999년에서 2001년 사이에 국내 저질 (11개 지점)에 대하여 5회씩 측정하였다. 저질시료는 완전히 건조시킨 후 디클로로메탄을 추출용매로 사용하여 초음파세정기로 추출한 후 GC/MS의 SIM 모드로 분석하였다. 그 결과 저질에서 DEP, DBP 및 DEHP만 검출되고 다른 프탈레이트는 검출되지 않았다. 저질의 경우는 DEHP가 27.3~63.6% 검출빈도를 나타냄으로써 제일 빈번히 검출되었고, 또한 이 물질은 평균 측정농도도 가장 높게 나타났다 (81.7~427.6 ng/g).
