Outline of Final Research Achievements

We developed a hybrid soil remediation system that combined the microbially-mediated arsenic mobilization with an arsenic hyperaccumulator plant Pteris vittata. The remediation system was constructed on a laboratory scale, in which hydroponics system of Pteris vittata was floated on the flooded arsenic-contaminated soil, and remediation experiments of arsenic-contaminated soil (200 mg-As/kg) were conducted. After 90 d of the experiments, As levels in the soils decreased to 66-117 mg/kg, which is below the soil concentration standard set by the Soil Contamination Countermeasures Law in Japan.

Academic Significance and Societal Importance of the Research Achievements

現在、ヒ素を含め金属類で汚染された土壌は、ほとんどが掘削除去により処理されているが、極めて高コストである。一方、より低コストな手法として、植物を用いたファイトレメディエーションの研究が長年行われてきたが、浄化効果が限定的なため、実用技術としてほとんど普及していない。本研究は、微生物と植物の機能を組み合わせ、双方の特長を活用することで、実用レベルの浄化効果が得られる事を示した。本研究の成果は、ヒ素汚染土壌浄化へのファイトレメディエーション適用において、大きな突破口となり得る。
