| Outline of Final Research Achievements |
A part of antibiotics administered to livestock excreted with excrements. The excrement is used to produce compost and spread to agricultural lands, which means antibiotics could be spread to soil and water environments. This study investigated sorption, mobility, and degradability of three types of antibiotics (tylosin, sulfamonomethoxine, and sulfamethazine) by three types of soil (andsol, brown forest soil, and gray lowland soil). In addition, acute toxic test was carried out to assess the toxicity of the degraded products to green algae.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の学術的意義は、土壌中の抗菌性物質の挙動を収着と分解について検討し、特に分解のメカニズムについて土壌微生物だけでなく、土壌中の鉱物の寄与も明らかにしたこと、さらに分解生成物の水域生態系の影響を評価した点である。土壌の理化学特性により抗菌性物質の土壌中の分解や分解生成物の特性について検討を進めることで、環境への負荷が低い抗菌性物質を選択して使用することが可能となると考える。この成果は薬剤耐性対策に寄与できる社会的意義を持っている。
