현이차 미분 형광 분광광도법을 이용하여 울산만 해양 저질토양중의 PAHs를 n-hexane용매로 추출하여 11종의 PAHs를 동시 정량분석하였다. Acenaphthene (Ace), anthracene (Anth), benzo(a)pyrene (BaP), benz(a)anthracene (BaA), benzo(b)fluoranthene (BbFt), benzo(k)fluoranthene (BkFt), chrysene (Chry), perylene (Per), phenanthrene (Phen), pyrene (Pyr) 및 fluoranthrene (Ft) 등을 정량분석 하였다. 이들 성분들의 검정선은 대략 0.15∼166 ppb의 농도범위에서 직선관계를 보였으며, 0.999이상의 좋은 직선 상관계수를 보였다. 울산만의 해양 저질 토양 (sediment)에 함유된 11 종의 PAHs 총량은 68.8 ng/g ∼ 324.4 ng/g의 농도범위로 함유되어 있었다. 또한 PAHs의 총량은 울산만의 안쪽으로 갈수록 증가하는 경향을 보였으며, 특히 Pyr과 BaA 등과 같은 4고리화합물의 함량비가 높았다.
Determination of some PAHs in sediments at Ulsan bay has been carried out by extraction of the components into n-hexane followed by synchronous spectrofluorimetric technique. 11 PAHs, such as acenaphthene (Ace), anthracene (Anth), benz(a)anthracene (BaA), benzo(b)fluoranthene (BbFt), benzo(k)fluoranthene (BkFt) benzo(a)pyrene (BaP), chrysene (Chry), phenanthrene (Phen), fluoranthene(Ft), perlyrene (Per), and pyrene (Pyr) in sediment samples were able to determine separately by synchronous spectrofluorimetry. Calibration curves for those components were linear for the concentration range of 0.15∼166 ppb PAHs with the correlation factor of 0.9985∼0.9999. The total amount of PAHs in sediments varied from 68.8 to 324.4 ng/g. The PAHs concentration was shown a tendency to increase from the outer bay to the inner basin as well the predominant contributors to the aromatic ring groups of the PAHs was 4-ring group.
