유류에 의한 해양오염은 해양환경에 심각한 영향을 미치기 때문에 사전에 방지되어야 함이 최선이다. 하지만 일단 사고가 발생한 경우는 신속한 방제조치와 아울러 피해자에 대한 신속하고도 적정한 손해배상이 이루어져야 한다. 이는 피해 국민들의 생존권 보호차원에서도 구체적으로 실현되어야 할 과제이다. 해양사고에 의한 유류오염 피해가 발생할 경우 가장 큰 영향을 받는 것는 해양 생태계 파괴에 따른 어업 피해라고 할 수 있는데, 지금까지 국내 유류오염사고에 대한 국제기금의 어업피해 보상율은 피해 청구액 대비 약 10～30%로 인접국이나 유럽 국가에 비해 현저히 낮은 수준이다. 이 연구에서는 최근 허베이 스피리트호 사고 피해보상 진행과정에서 나타난 문제점을 분석하여 국내 해양 유류오염사고 손해배상율 제고방안을 제시한다.

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.

유류오염 사고를 사전에 예방할 수 있는 정책 수단으로는 여러 가지가 있지만 주요한 것으로는 인센티브제의 활용을 들 수 있다. 유류오염 사고를 예방하고 관리하기 위한 인센티브는 유출 사고로 인해 발생한 해양자원의 피해에 대해 가해자에게 배상책임(liability for losses due to spills)을 부과함으로써 제공될 수 있다. 유류오염 사고로 인한 피해액을 실제 화폐단위로 계량화하는 작업은 배상책임 부과제도를 정책수단으로 활용하기 위해 해결해

Microorganisms producing bioemulsifier were isolated from the sea water in Pusan coastal area. The isolated strain which had the highest emulsification activity and stability was identified as the genus Acinetobacter from the results of morphological, cultural and biochemical tests and named Acinetobacter sp. EL-C6 for convenience. The compositions of optimum medium for emulsification of crude oil by Actnetobacter sp. EL-C6 were crude oil 2.0%, NH_4NO_3 0.2%, K_2HPO_4 0.01%, MgSO_4·7H_2O 1.0%, CaCl_2·2H_2O 0.1% and NaCl 3.0% at initial pH 7.5 and 30℃, respectively. The cultivation for emulsification of crude oil was carried out in 500㎖ shaking flask containing 100㎖ of the optimum medium at 30℃. The highest emulsification was observed after 5 days. The utilization on the various hydrocarbon of the Acinetobacter sp. EL-C6 showed that utilization of n-alkane compounds were better than that of aromatic compounds. Among the petroleum compounds, crude oil was best utilized by the Actnetobacter sp. EL-C6.
