초록
조리 어패류 중 8종의 PAHs 실태파악을 위하여 어류 168건, 패류 40건을 분석하였다. 시료를 알칼리분해하여 n-hexane으로 추출하고 세척한 후 Sep-Pak Florisil Cartridge로 정제하여 HPLC/FLD로 정량 분석하였다. 각각의 PAHs에 대한 회수율은 약 88~112%였다. 조리어류에서 개별 PAH 평균 농도는 benzo(a)anthracene 불검출, chrysene 불검출, benzo(b)fluoranthene 0.0009 ㎍/㎏, benzo(k)fluoranthene 불검출, benzo(a)pyrene 0.01 ㎍/㎏, dibenzo(a,h)anthracene 불검출, benzo(g,h,i)perylene 불검출, indeno(1,2,3-c,d) pyrene 불검출이었다. 조리패류에서 개별 PAH 평균 농도는 benzo(a)anthracene 1.84 ㎍/㎏, chrysene 3.51 ㎍/㎏, benzo(b)fluoranthene 0.81 ㎍/㎏, benzo(k)fluoranthene 0.38 ㎍/㎏, benzo(a)pyrene 0.39 ㎍/㎏, dibenzo(a,h)anthracene 0.04 ㎍/㎏, benzo(g,h,i)perylene 0.20 ㎍/㎏, indeno(1,2,3-c,d)pyrene 불검출이었다.
Abstract
The following concentrations of some PAHs were investigated; [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] in fish(n=168) and shellfish(n=40). The methodology involved saponification and extraction with n-hexane, clean-up on Sep-Pak Florisil Cartridges and determination by HPLC/FLD (High Performance Liquid Chromatograph/Fluorescence Detector). Overall method recoveries for 8 PAHs spiked into these products ranged from 88 to 112%. The mean level of benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k) fluoranthene, benzo(a)pyrene, dibenzo(a,h)anthracene, benzo(g,h,i)perylene and indeno(1,2,3-c,d)pyrene in cooked fish was ND, ND, 0.0009, ND, 0.01, ND, ND, ND and in cooked shellfish was 1.84, 3.51, 0.81, 0.38, 0.39, 0.04, 0.20, ND, respectively.
