본 연구에서는 토양내 BaA 농도로부터 BaP, DahA와 ${\Sigma}PAH$의 농도 예측식 개발과 토양 재활용을 위하여 통계적 접근을 시도하였다. 회귀분석 결과 높은 상관성($R^2$ > 0.90)과 BaA와 BaP(또는 DahA) 농도 사이에 밀접한 연관성을 보였다. 또한 개발된 회귀식을 다른 검증 연구에 적용한 결과 유사한 예측값을 얻었다. 통계적 분석에서 BaA가 BaP 예측에 높은 상관성을 보였으며 PAHs 예측에 중요한 인자로 여겨진다. 이들 예측식을 적용 할 경우 BaA 농도만을 이용하여 평균적인 BaP, DahA나 ${\Sigma}PAH$ 농도를 빨리 계산 할 수 있다.

Polycyclic aromatic hydrocarbons (PAMs) are ubiquitous contaminants in marine environments. PAMs enter estuarine and nearshore marine environment via several routes such as combustion of fossil fuels, domestic and industrial effluents and oil spills. PAHs have been the focus of numerous studies in the world because they are potentially carcinogenic, mutagenic, and teratogenic to aquatic organisms and humans from consuming contaminated food. However, one can hardly find any available data on PAM content in marine organisms in Korea. The present study was carried out in order to determine PAM content in oysters from the intertidal and subtidal zones of Chinhae Bay, which is located in near urban communities and an industrial complex, and the bay is considered to be a major repositories of PAHs. 16 PAHs were analyzed by High Performance Liquid Chromatography (HPLC) with uv/vis and fluorescence detectors in oysters: they are naphthalene (NPTHL), acenaphthylene (ANCPL), acenaphthylene (ACNPN), fluorene (FLURN), phenanthrene (PHEN), anthracene (ANTHR), fluoranthene (FLRTH), pyrene (PYR), benzo(a)anthracene (BaA), chrysene (CHRY), benzo(b)fluoranthene (BbF), benzo(k)fluoranthene (BkF), benzo(a)pyrene (BaP), dibenz(a,h)anthracene(DahA), benzo(g,h,i)peryne (BghiP) and indeno(1,2,3,-cd)pyrene (I123cdP). The PAM contents in oysters from the intertidal and subtidal zones of Chinhae Bay ranged from < 0.1 to 992.0 ug/kg (mean $69.8\pm9.8$ ug/kg).
