Fall 2025 WRRC Seminar

October 20, 3:00pm - 4:00pm
Mānoa Campus, Kuykendall Hall Room 201

Emerging contaminants, such as micro- and nanoplastics (MNPs), have become ubiquitous in aquatic environments, posing growing concerns for ecosystem and human health. Yet, major knowledge gaps remain regarding their sources, formation mechanisms, and toxicological effects. This seminar will present an integrative research framework that combines experimental analysis, modeling, and data-driven approaches to illuminate the sources, release mechanisms, and biological impacts of MNPs. Drawing on case studies from synthetic textiles, Dr. Yang will demonstrate how microplastic fibers and nanoplastics are generated during daily uses, revealing previously unrecognized oligomer particles that blur the boundary between dissolved organic matter and nanoplastics. He will also highlight how probabilistic risk assessment and machine learning can bridge data gaps and improve the prediction of ecological risks for MNPs and other emerging contaminants, such as PFAS. Looking ahead, Dr. Yang will outline a vision for a predictive aquatic toxicology platform that integrates omics-based biomarkers, computational modeling, and community-engaged monitoring to address contaminant challenges unique to 好色先生网站鈥榠鈥檚 ecosystems. This interdisciplinary approach aims to advance mechanistic understanding, inform water-quality policy, and strengthen the resilience of island environments in the face of global change.
