Fall 2025 WRRC Seminar

October 3, 2:00pm - 3:00pm
Mānoa Campus, https://hawaii.zoom.us/meeting/register/9yU-LCTDSF6EL6cEHHITUA

Marine debris and microplastics have emerged as a critical global environmental pressor, threatening marine ecosystems, fisheries, coastal livelihoods, and human health. Their persistence, mobility, and interactions with chemical pollutants complicate both assessment and management. This talk explores current knowledge on sources, distribution, and ecological risks of marine debris and microplastics, with a focus on challenges that hinder effective prevention and control—such as transboundary transport, gaps in monitoring standards, and the limitations of existing waste management systems. A case study from Xiamen, China, a typical coastal environment, highlights how human activities, geomorphology, and hydrodynamics influence pollution levels. Building on these insights, the presentation evaluates potential solutions, ranging from upstream interventions in plastic production and circular economy strategies, to downstream approaches like advanced wastewater treatment, policy frameworks, and community-based initiatives. The goal is to provide a comprehensive perspective on bridging science, policy, and practice in tackling marine debris and microplastics, ultimately promoting resilient coastal ecosystems and sustainable ocean governance.
