In this study, the concentrations of various hydrocarbon (HC) were measured from the ambient air at Mallipo beach after the Hebei Spirit oil spill accident on Dec. 2007. To determine HC levels in those samples, the analysis was made by SPME method aided by the GC/MS system. To produce quantitative HC data, all the calibrations were conducted in reference to toluene. The HC released from oil-covered soils were also analyzed by headspace method; according to this analysis, the concentrations of paraffinic (9), aromatic (8) and miscellaneous components (5 compounds) were found above a few tens of ppb. In ambient samples, 10 compounds were measured which consisted of 8 paraffinics and 2 aromatics. And they have the maximum and minimum concentration that were 34.3 ppb (n-undecane) and 2.84 ppb (toluene). However, the concentration levels of the 2 aromatic compounds (toluene and xylene) measured during this study period were not distinguished from those commonly observed from ambient air. Based on our analysis, we were able to confirm that the types and the concentration levels of hydrocarbons in ambient samples were in accord with those derivable from a large oil spill accident and the resulting weathering processes.

광양만 및 주변 하천에 존재하는 페놀류 화합물과 sterol 화합물의 분포특성을 알아보기 위하여 alkylphenols (8종), chlorophenols (2종), bisphenol A (1종), coprostanols (2종) 및 cholesterol (1종) 등 화합물들을 분석대상물질로 선정하여 표층수와 표층퇴적물 시료를 분석하였다. 모든 분석대상물질 중에서 nonylphenol과 dihydrocholesterol 화합물이 가장 높은 검출빈도를 보

PCB 화합물 및 유기기염소계농약류는 난분해성이며 독성이 높은 대표적인 유기오염물질로서 환경 중에 배출되면 오랜 시간 잔류하게 된다. 대부분의 유기염소계화합물은 우선적 관찰 및 규제 대상물질로 분류되어 지구적 관심을 모으고 있다. 광양만은 대단위의 공업단지가 밀집해있고 반폐쇄적인 지형학적 구조를 가지고 있어 유기염소계화합물의 오염이 우려되는 대표적인 해역이다. 본 연구에서는 오염 모니터링에 대표적으로 이용되는 퇴적물과 부착성 이매패류를 채집하여 분석함으
