Professor Xuchun Qiu's research lab specializes in environmental toxicology and nanomaterial safety, focusing on the impacts of emerging contaminants—such as pharmaceuticals, surfactants, heavy metals, and engineered nanoparticles—on aquatic organisms. The lab investigates the behavioral, physiological, and biochemical responses of fish, particularly zebrafish and medaka, to chronic and sublethal exposures, with an emphasis on neurotoxicity, oxidative stress, and neurotransmitter disruption. They also explore advanced materials for environmental remediation, including magnetic and imprinted photocatalysts for selective pollutant degradation.

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.
