Abstract
PAHs(Polycyclic Aromatic Hydrocarbons) are widespread contaminants in the marine environment. They are of mainly anthropogenic origin from urban runoff, oil spill and combustion of fossil fuels. Some PAHs are potentially carcinogenic and mutagenic to aquatic organism The contamination of PAHs in the coastal environments has not been well known yet in Korea. This study was carried out to survey the contamination of PAHs in sediments around Gwangyang bay. The Yeosu petrochemical industrial complex, POSCO(Pohang steel company) and Gwangyang container harbor are located around the bay. PAHs in sediment samples were extracted in soxhlet extractor and were identified and quantified by GC-MS(Gas Chromatography-Mass Spectrometry) TOC(Total Organic carbon) and textural parameters in sediment samples were also analyzed 13 species of PAHs were detected at all of the surface sediments. Total PAHs concentrations in the surface sediments ranged from 171.40 to
PAHs는 해양환경 중에 넓게 분포되어 있으며 인간활동에 의한 화석연료 이용으로 PAHs의 오염이 광범위하게 일어나고 있다. PAHs는 잠재적으로 해양 수서환경 생물에 발암성과 돌연변이를 일으키고 있다. 본 연구는 여수화학공단, 광양제철소와 콘테이너부두가 자리잡고 있는 광양만의 표층퇴적물에서의 PAHs를 Soxhlet Extractor를 이용하여 추출하여 GC-MS로 PAHs 13종을 검출하였고 TOC(Total Oragnic Carbon)와 입도분석을 행하였다. 분석된 퇴적물에서 PAHs 화합물 모두가 검출되었으며 Total PAHs 범위는
