Outline of Final Research Achievements

Chemical analysis of coral samples in the estuary and analysis of outflow patterns by satellite remote sensing and numerical model were carried out to understand the actual situation of heavy metal outflow to the coast of the Dominican Republic. The study suggests that heavy sanitation in the capital Santo Domingo is insufficient for living and industrial waste treatment facilities, and that heavy metals may be brought to the sea area from the large river represented by the Haina River. In particular, it has become clear that lead contamination from battery factories can be detected by massive corals. In addition, it was also found that flood events such as hurricanes have serious impacts from other sources.

Academic Significance and Societal Importance of the Research Achievements

ドミニカ共和国は,周囲がカリブ海で囲まれる風光明媚な国である.一方,ハリケーンの通り道としても知られ,ハリケーンなどのイベント後には陸域から大量の汚染物質がカリブ海に流出する懸念が常にある.本研究では,特に重金属汚染が問題となるハイナ川河口とサマナ湾などを対象として,サンゴ試料や衛星・数値モデルなどを使って重金属の流出実態を明らかにした.このような試みは過去にはなく,学術的・社会的に非常に意義深い.
