 note = {家畜へ投与された抗菌剤の一部は排泄物中に排出される．そのため抗菌剤が畜産廃水と共に周辺の水環境に流出し，水域生態系に悪影響を及ぼす可能性がある．本研究では，イライトまたはゼオライトを主要粘土鉱物とする2種類の鉱物試料（Y-illite, M-Zeolite）との接触による溶液中及び養豚廃水中に添加した3種類の抗菌剤の除去処理試験を行った．さらに処理水の安全性について，藻類R.subcapitataを用いた短期毒性試験により検討した．その結果，M-Zeoliteの方がY-illiteよりも抗菌剤の除去速度が速いことが示された．また，タイロシンは吸着だけでなく分解も生じる可能性が示唆された．さらに，実際の養豚廃水を用いた除去試験より，人工湿地の後段 にゼオライトでの接触処理を取り入れることで，より効率的に抗菌剤が除去できることを明らかにした．, Certain antibiotics administered to livestock are released in their excrement. Therefore, antibiotics may combine with livestock wastewater and enter the surrounding water environment, affecting the aquatic ecosystem. In this study, we investigated antibiotics removal from aqueous solution and swine wastewater via contact with clay minerals (zeolite, illite). Furthermore, the safety of the treated water was investigated by a short-term toxicity test using a green alga R. subcapitata. It was observed that zeolite had a higher antibiotics removal rate than illite. Additionally, it was suggested that the removal of tylosin may involve degradation and adsorption. Furthermore, the experimental results of antibiotic removal from swine wastewater indicated that antibiotics can be efficiently eliminated by incorporating the contact treatment using zeolite, after its treatment in constructed wetlands.},
