  • The Hebei Spirit oil pollution accident which occurred in Tae-an in 2007 has brought considerable impacts on the surrounding environment such as struggles among the regions and the residents in the damaged area as well as devastation of local economy and ocean environment. The majority of the impact was related with economic problem. Also, the main factor to cause the regional community conflict was found to be firstly economic problems and secondly the insufficiency of government's management system and policy measures for the community conflicts. Therefore, the government's policy to overcome oil accidents should focus on improvement of the economic support systems and conflict resolution. In this study, the support policies taken by government after the Hebei Spirit accident was examined and responsive policies which can be used by government in future accidents are suggested.

  • After oil outlow accident of Hebei spirit in December 7, 2007, the motality of manila clam, Ruditapes philippinarum in the west coast of South Korea, was significantly increased from 9.2% in April, 2007 to 22.4% in April 2008. Although the mortality was about 10% in the tidal flat of Geunso Bay and Cheonsu Bay, Incheon and Gyeonggi-do, the values was significantly high about 30% in water coast of Taean, Boryeong and Seosan in where the spilled oil was getting into fishery zone. However, the mortality in water coast of Taean, Boryeong and Seosan was decreased from 22.4% in 2008 to 6.0% in 2009. Also, we found that the mortality in contaminated and non-contaminated water zones was both slightly increased from 6.0 in 2009 to 8.6% in 2010, Therefore, these results are indicating that the significant high mortality observed in water coast of Taean, Boryeong and Seosan at April, 2008 was due to the crude oil accident outflow from tanks of Hebei spirit. Although the mortality of manila clam was significantly decreased in middle west coast of South Korea after the accident of Hebei spirit in December, 2007, the annual production of manila clam in South Korea was sustainedly from 27,459 ton in 2007, 36,302 ton in 2008, 40,392 ton in 2009, to 36,248 ton in 2010. In the production of manila clam by regional groups, the amount in sea coast of Chungnam, where was damaged by crude oil, was significantly decreased from 10,598 ton in 2007 to 5,048 ton in 2008, but then was significantly increased to 7,065 ton in 2009, and to 12,921 ton in 2010. However, in sea coast of Jeonnam that was not damaged by crude oil, the amount was significantly increased from 1,252 ton in 2007 to 12,248 ton in 2008, but then was significantly decreased to 9,566 ton in 2009, and to 2,770 ton in 2010. Therefore the results are suggesting that a increasing of the total annual production of manila clam in South Korea in 2008 when was 1 year after the oil accident of Hebei spirit was due to increasing of clam production in a coast of Jeonnam in where was not damaged by crude oil.

  • The purpose of this study intends to suggest a basic information to establish protected area policy by analyzing environmental consciousness and environmental protection behavior of citizen after Hebei Spirit oil spill. During May-June of 2011, a total of 987 respondents completed at 5 major cities (Seoul, Busan, Daegu, Daejeon, Gwangju) in Korea. The result showed that more previous experience of environment as recognition of oil spill damaged area, volunteer activity experience, participation in the organization for environmental conservation, and participation in education program led to more positive attitude to environment. Therefore, the result of this study will contribute to manage protected area in balancing ecological conservation and utilization.

  • The in vitro toxicities of three crude oils of the Hebei Spirit were examined on laboratory grown plankton, with a focus on the effects of a dispersant. The specific growth rate of phytoplankton and the mortalities of two zooplankton were measured in response to exposure to various concentrations of water accommodated oil, dispersant or both. The effects of the oils varied among the plankton, but were generally low within the range of the oil concentrations used, with little difference in toxicity among the three oils. Such low toxicity appeared to be associated with weathering of the crude oils. Exposure to the dispersant, however, dramatically increased the mortality of zooplankton, with complete inhibition of phytoplankton growth. No synergistic toxic effect was observed with the crude oil and dispersant combination. A better decision making process could be crafted for future application of dispersant in the event of an oil spill in Korean waters to better protect the marine plankton community from the excessive use of dispersant.

  • The residual oil concentrations in seawater and sediments were investigated along the Taean coast of Korea, following the Hebei Spirit oil spill, which occurred on 7 December 2007. The oil concentration in seawater ranged from 0.059 to $0.866\;{\mu}g/L$ for the tidal flat culture grounds and from 0.016 to $0.943\;{\mu}g/L$ in the fish cage areas in 2008. These were dominated by the seawater temperature relationship. Polycyclic aromatic hydrocarbons (PAHs) in sediments were also analyzed and the concentrations ranged from 3.4 to 509.7 ng/g dry weight. The average PAH level was higher in seawater from the Sinduri area than the Padori area, while the average PAH level in sediments was higher in Padori. The diagnostic ratio of PAHs was investigated to determine the origins of the PAHs. The PAHs in the Seongam area, which was not affected by the oil spill, are of pyrolytic origin, while the PAHs in Padori and Sinduri were of petrogenic origin. The residual oils in the areas affected by the oil spill tended to decrease over time, except in summer. The oils in pore water remained 6- to 16-fold higher, as compared to the seawater overlying the tidal flat, implying that residual oils will continue to influence the affected region for the foreseeable future.

  • Oil spills are a principal factor of the ocean pollution. The complicated problems involved in detecting oil spills are usually due to varying wind and sea surface condition such as ocean wave and current. The Hebei Spirit accident was happened in the west sea ($36^{\circ}$41'04" N, $126^{\circ}$03'12" E) near about 8 km distant from Tae-An, Korea on December 7, 2007. The aim of this work is to improve the detection and classification performance in order to define a more accurate training set and identifying the feature of oil spill region. This paper deals with an optimization technique for the detection and classification scheme using multi-frequency and multi-polarization SAR and optical image data sets of the oil spilled sea. The used image data are the ENVISAT ASAR WS and Radarsat-1 of C-band and ALOS PALSAR of L-band SAR data and KOMPSAT-2 optical images together with meteorological or oceanographic data. Both the theory and the experimental results obtained are discussed.

  • The purpose of this study is to evaluate the effects of oil dispersant and ultraviolet (UV) radiation on the toxicity of crude oil. The toxicity of water-accommodated fraction (WAF) and chemically enhanced water-accommodated fraction (CEWAF) of Hebei Spirit crude oil was investigated in the embryo of the Manila clam, Ruditapes philippinarum with- and without ultraviolet radiation. The WAF and CEWAF with- and without UV radiation affected significantly the embryonic development of R. philippinarum. The EC50s of WAF without UV, WAF with UV, CEWAF without UV, and CEWAF with UV were 2.82, 0.79, 1.60, and 0.45 g/L, respectively. CEWAF was 1.6 times more toxic than WAF. UV radiation increased crude oil toxicity to 3.6 times for both WAF and CEWAF. The oil dispersant and UV radiation did not affect the acute toxicity to the embryo but retarded the period of embryonic development up to 26%. R. philippinarum proved to be a sensitive species to reflect the toxic effects of oil spill combined with oil dispersant and UV radiation. It is suggested that the chemical analyses on the WAF and CEWAF is important for the identification and quantitative explanation of the phototoxic compounds in crude oil.
