Outline of Final Research Achievements

The large-scale natural disasters cause serious pollution of harmful chemicals in affected area, resulting in secondary damage to humans and ecosystems. The purpose of this study is to establish a future prediction and risk monitoring system for aqueous environmental pollution by heavy oil spill, using the Great East Japan Earthquake as a model case. As a result, the environmental half-lives of polycyclic aromatic hydrocarbons, which are harmful components of heavy oil, was less than 2 years, indicating that the pollution on the affected area may not be prolonged. In addition, heavy oil contains a large amount of unknown components, and that burning of heavy oil produces a new substance.
Japan is expected to have a great damage from the earthquake and Tsunami that originates from the Nankai Trough. The results obtained in this study has gained insights useful for the prediction of pollution at the time of a fuel oil spill and mitigation by the large-scale natural disaster.

Academic Significance and Societal Importance of the Research Achievements

大規模な自然災害は被災地沿岸に有害な化学物質を流出させ、ヒトや生態系に甚大な二次被害をもたらす。本研究は東日本大震災をモデルケースにして、重油流出による水環境汚染の未来予測とリスク監視システムの構築に資する結果を得た。近い将来、日本は南海トラフを震源とする地震と津波で甚大な油汚染が発生する可能性が高い。本研究を含め、来るべき大規模災害に備えた科学的知見を今のうちから収集・蓄積することは、市民や行政や化学汚染対策を考える上で重要かつ意義深いと考えられる。
