Abstract
최근 내분비계장애물질로 알려진 PAHs 화합물 중 하나인 벤조피렌은 대표적인 PAHs 화합물로 음식을 조리, 가공할 때 식품의 주성분인 탄수화물, 단백질, 지방 등이 분해되어 생성되는 열분해 산물이며 토양, 공기, 물, 식품 등 전 환경매체에서 검출되고 있다. 본 연구에서는 PAHs〔benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, dibenzo(a,h)anthracene, benzo(g,h,i)perylene, indeno(1,2,3-c,d)pyrene〕에 대하여 어류 중 지방의 알칼리 분해시간에 따른 분해효율, 추출 용 매에 따른 추출효율, 정제컬럼의 용출량에 따른 정제효율 등을 비교 실험하여 알칼리분해를 이용한 어류중 PAHs의 전처리방법을 확립하고자 하였다. 균질화된 시료를 알칼리 분해하여 n-hexane으로 추출하고증류수로 세척한 후 Sep-Pak florisil cartridge로 정제하여 HPLC/FLD(고속액체크로마토그래피/형광 검출기) 로 동시 정량 분석하였으며 각각의 PAHs에 대한 회수율은 약 90~106% 수준이었다.
