  • 본 연구는 충남 태안에서 발생한 허베이 스피리트 유류유출 사고 직후 유류오염이 대형저서동물 군집에 미치는 초기 영향을 알아보기 위해 사고, 10일 후인 2007년 12윌 18일부터 22일까지 72개 정점을 대상으로 조사를 실시하였다. 사고 주변 해역에서 출현한 대형저서동물은 총 228종, 서식밀도는 561 개체 $m^{-2}$였으며, 생물량은 39.7 gww $m^{-2}$였다. 본 연구에서 가장 많은 개체수를 보인 대형저서동물은 단각류의 Ampelisca sp.였다. 그러나 이 종은 유류 오염에 민감한 종으로 유류오염의 직접적 영향을 받았던 만리포 주변 해역에서는 전혀 출현하지 않았다. 반면 기회주의적 다모류에 속하는 얼굴갯지렁이류의 Prionospio bocki, Prionospio cirrifera가 만리포 주변 해역에서 우점하게 나타나는 등 유류오염에 의한 징후가 나타났다. 또한 유류사고 직전에 수행된 연구 결과들에 비해 서식밀도 및 생물량 조성이 크게 감소하였다. 그러나 일부 해사채취해역에 위치한 정점들에서는 유류사고 전후의 군집조성이 큰 차이를 보이지 않았다.

  • 해양사고 발생시 대응능력 향상을 위해 대응훈련 및 이를 위한 시나리오 개발이 필요하다. 본 연구에서는 위험유해물질 유출사고 대응체계 구축의 일환으로 가상 위험유해물질 유출사고에 대한 대응 시나리오를 개발하였다. 가상 시나리오는 부산 해역을 대상으로 개발하였으며, 대상해역에서 발생될 수 있는 가상 사고 시나리오와 이에 대한 대응 시나리오를 각각 개발하였다. 가상 사고 시나리오는 대상해역인 부산해역의 위험평가 및 취약성분석을 통해 발생될 수 있는 위험유해물질 유출사고를 선정하고, 가상 사고로 인해 발생될 수 있는 피해를 예측하여 구축되었다. 가상 사고에 대한 대응 시나리오는 가상 사고 시나리오의 피해예측에서 제시된 피해를 수습하기 위한 단계별 조치사항으로서 제시하였다. 부산해역의 위험유해물질 가상 유출사고는 부산 감천항 충돌사고로 인한 자일렌(xylene) 1,000톤 유출사고로 선정하였으며, 이로 인한 피해는 자일렌의 대기확산 및 해양확산 계산을 통해 예측하였다. 또한 가상 사고에 대한 대응 시나리오는 피해지역의 주민 대피, 자일렌 확산 방지 및 회수, 대응요원 보호조치, 사고지역 사후 관리 등에 대한 단계별 조치사항을 제시하였다.

  • 지난 2007년 서해안에서 발생한 Hebei Spirit 호 기름유출사고는 국가방제능력 2만톤 확보, 유출확산 시뮬레이션, 방제선 및 방제장비 등의 대비를 무색하게 할 만큼 엄청난 환경적 경제적 피해를 발생시켰다. 사고에 따른 피해가 사고시 기상 및 해역조건과 더불어 기름유출사고로 인하여 해상에서 방제활동에 초점이 맞춰진 현재 방제방법의 한계를 알아보고 우리나라 서해안에서의 효율적인 방제활동 방안을 고찰하고자 한다.

  • In Korea for 20 years(1993-2012), total number and average annual number of oil spills were 6,608 cases and total volume and average annual volume of oils spilt were $57,328k{\ell}$ and nearly $2,866k{\ell}/year$, respectively. The annual number of oil spills and annual amount of oil spilt tended to decrease with the lapse of year in Korea. As oil transportation worldwide continues to increase, many communities are at risk of oil spill disasters and must anticipate and prepare for them. Factors that influence oil spill consequences are myriad and rage from the biophysical to the social. In this paper, we analysed the emergency response systems and recovery apparatuses for oil spill accident in marine and proposed a developed oil diffusion apparatus which can be used to initial response stage by crew, and to extend golden times. This system can be minimized casualties for rescued people in disaster.

  • This study investigates the effects of tide, wind and oceanic currents on oil spill dispersions through a series of numerical floats tracking experiments on the Sea Prince oil spill incident occurred in 1995 using a 3-dimensional high resolution ocean circulation model. For that, a total of four experimental cases (experiment with tide, wind and oceanic currents, experiment with tide and oceanic currents, experiment with wind and oceanic currents, and experiment with tide and wind) were compared. It could be seen that results from experiment involving all external forces showed better agreement with the observed pattern of oil slick movement than other cases. The oceanic currents acted to drive floats to move to the western channel of the Korea straits and wind accelerated the eastward movement of floats in the early stage of the incident. Tidal currents played significant role in the horizontal dispersion of floats.

  • This study aimed to analyze the economic effectiveness on environment improvement project that has been implemented in five fishing grounds of Taean-gun which had been damaged by the Hebei Spirit oil spill accident. In the analysis, first, this study performed the survey on residents perceptions about the environment improvement project. Second, the cost-benefit analysis was carried out to evaluate the economic effectiveness of the project. The survey results of residents perceptions indicated that the damage of oil spill was considerable in the target areas. It also showed that residents wanted to continue the environment improvement project and the levels of project satisfaction were quitely high. The economic results showed that 3 areas(Woong-do, Wang-san, and Dang-mi) would have positive values of NPV and B/C ratio, but the other(Nu-dong) would have negative values. The findings of this analysis could be used as the base data for increasing operational efficiency of future environment improvement projects.

  • In this study, a new numerical modeling system was proposed to predict oil spills, which increasingly occur at sea as a result of abnormal weather conditions such as global warming. The hydrodynamic conditions such as the flow velocity needed to calculate oil dispersion were estimated using a three dimensional hydrodynamic model based on the Navier-Stokes equation, which considered all of the physical variations in the vertical direction. This improved the accuracy compared to those estimated by the conventional shallow water equation. The advection-diffusion model for the spilled oil was combined with the hydrodynamic model to predict the movement and fate of the oil. The effects of absorption, weathering, and wind were also considered in the calculation process. The combined model developed in this study was then applied to various test cases to identify the characteristics of oil dispersion over time. It is expected that the developed model will help to establish initial response and disaster prevention plans in the event of a nearshore oil spill.

  • Polycyclic aromatic hydrocarbons (PAHs) were investigated in seawater and marine sediment from Anmyundo coastal area after oil spill. The concentrations of total PAHs in surface and bottom of seawater at August were 31.1 to 142.6 ng/L and 5.9 to 50.9 ng/L in August and November, respectively. The concentrations of PAHs in sediment were 21.0 to 102.9 ng/g D.W. and 32.3 to 57.4 ng/g D.W. in August and November, respectively. PAHs concentrations in seawater and sediment in August were higher than those in November about 2.5 and 1.4 times, respectively. Diagnostic ratio (PhA/AnT and FluA/Pyr) were investigated to identify source of PAHs in seawater and sediment. The PAHs in seawater originated from pyrolytic source and those in sediment originated from pyrolytic and petrogenic source. The glass, wood and coal origin was higher than petroleum origin on the combustion origin of PAHs in seawater and sediment. The seawater of Anmyundo costal area recovered from oil spill, but the sediments of that were weakly influenced by oil spill until now. Because this area is developed many fishing grounds, demanded Long Term Environmental Monitoring Program (LTEMP). The concentrations of PAHs on depth of sediments were investigated at station 8 and 10. The concentrations of PAHs were decreased with increasing depth.

  • Objectives: The aim of this study was to assess exposure to VOCs and PAHs and the health effects on volunteers who participated in an oil spill cleanup in Yeosu. Methods: Atmospheric VOCs were evaluated in the vicinity of the accident site and questionnaire surveys were conducted to identify personal characteristics and acute health symptoms of clean-up workers seven days after the accident. The levels of metabolites of VOCs (t,t-MA, HA, PGA, MA, MHA) and PAHs (2-NAP, 1-OHP, 2-HF, 1-HPH), oxidative stress markers (TABARS, 8-OHdG) in the urine of workers were analyzed. Their correlation was determined by multiple regression analysis with SAS ver. 9.4. Results: Although the concentration of atmospheric VOCs in the residential areas were low at the time of survey, the levels of VOCs and PAHs metabolites in clean-up workers were higher than those in the control group after clean-up activities. The levels of urinary VOC and PAH metabolites were significantly increased after clean-up compared to those measured before participation. The thiobarbituric acid reactive substance (TBARS) concentrations were also increased and showed significant correlations with those of metabolites of benzene. Conclusion: This study shows that oil spill clean-up activities affect exposure to VOCs and PAHs and the health of clean-up workers. The results suggest the need for check-ups of participants in oil spill cleaning work.
