초록
낙동강 수계는 중·상류 지역에 대규모 공단이 입지하고 있어 그동안 phenol, 1,4-dioxane, perchlorate 등 유해물질에 의한 수질오염사고가 많이 발생하였다. 본 연구에서는 낙동강 수계에 유출 가능성이 있는미규제 유해물질 중 반휘발성유기화합물질(semi-volatile organic compoumsds, SVOCs) 10종(dichlorvos,toluene-2,4-diisocyanate, 4,4'-methylenedianiline, 4,4'-methylenebis(2-chloroaniline), diethyl phthalate, di-n-butyl phthalate, butyl benzyl phthaltate, bis(2-ethylhexyl)adipate, benzophenone, 4,4'-bisphenol A)에 대하여 디스크형 고상 추출법과 GC/MS를 이용하여 분석하였으며, 정확도 75.6~110.5%, 정밀도 4.6~12.7%, 회수율72.4~127.9%의 결과를 얻을 수 있었다. 낙동강 수계에 위치한 하·폐수처리장 및 폐수배출업소 등 공장폐수 시료를 분석한 결과 bis (2-ethylhexyl)adipate, benzophenone, 4,4'-bisphenol A 등 3개 물질이 검출되었다.
Abstract
There are many industrial factories in the central Nakdong river basin and have been occurred water pollution accidents by hazardous chemicals such as phenol, 1,4-dioxane and perchlorate. In this study, ten compounds of semi-volatile organic compounds (SVOCs) (dichlorvos, toluene-2,4-diisocyanate, 4,4'-methylenedianiline, 4,4'-methylenebis (2-chloroaniline), diethyl phthalate, di-n-butyl phthalate, butyl benzyl phthaltate, bis (2-ethylhexyl)adipate, benzophenone, 4,4'-bisphenol A) of hazardous chemicals which may be potentially discharged into the Nakdong river, were determined by gas chromatography-mass spectrometry (GC-MS) with disk-type solid-phase extraction. Accuracy and precision were in the range of 75.6~110.5%, and 4.6~12.7%, respectively and recovery was in the range of 72.4~127.9%. Three compounds (bis (2-ethylhexyl)adipate, benzophenone, 4,4'-bisphenol A) were detected in industrial wastewater such as wastewater treatment plants (WWTPs) and wastewater discharge facilities in the Nakdong River basin.
