Xuchun Qiu教授の研究室は、環境中における医薬品・化学物質・ナノ材料の生態リスクを解明することを主眼としています。特に、魚類を用いた行動異常、神経伝達物質や酸化的なストレスマーカーとの関連を解析することで、環境汚染物質の潜在的影響を評価しています。近年では、光触媒材料の開発や、複数の汚染物質が併存する状況における相互作用の解明にも注力しています。

Residues of the psychoactive drug diazepam (DZP) may pose potential risks to fish in aquatic environments, especially by disrupting their behavioral traits. In this study, female and male zebrafish were subjected to chronic exposure (21 days) to sublethal doses (120 and 12 µg/L) of DZP, aimed to compare the characteristics of their behavioral responses to DZP exposure, and to investigate the possible links between those behavioral responses and variations in their brain γ-aminobutyric acid (GABA
The widely used compound tributyltin (TBT), which can be continuously detected in aquatic species and seafood, may induce diverse adverse effects on aquatic organisms. However, little is known regarding the mechanistic links between behavioral abnormality and oxidative stress in different fish tissues in response to oral TBT exposure. Herein, juvenile Japanese medaka (<i>Oryzias latipes</i>) were orally exposed to TBT at 1 and 10 ng/g-bw/d for four weeks. After exposure, the locomotor activity a
A POPD–CdS heterojunction embedded magnetic imprinted photocatalyst achieves the purpose of selective photodegradation of ciprofloxacin and effectively suppresses the secondary pollution caused by CdS photocorrosion.
