Marine Plastic Monitoring, Assessment, and Policy Khalida Jabeen,12 Daoji Li,12 Wei Nian,12 Muhan Su,12 Xinyu Bu121State Key Laboratory of Estuarine and Coastal Research, East China Normal University, Shanghai 200062, China2 Regional Training and Research Center on Plastic Marine Debris and Microplastics, IOC-UNESCO, Shanghai 200241, China Abstract Marine plastic pollution is a significant global issue causing harm to marine ecosystems, economies, and human health. Millions of tons of plastic debris enter marine environments annually, originating from various sources such as land-based runoff, wastewater discharge, improper waste management practices, shipping, and aquaculture. Effective monitoring, assessment, and policy interventions are crucial to address this issue.Monitoring involves collecting and analyzing data to determine the source, amount, and impacts of plastic debris. Techniques include oceanographic surveys, remote sensing, and citizen science initiatives. Assessment frameworks are essential for understanding the impacts of plastic pollution on marine ecosystems and informing stakeholders. Policy frameworks emphasize prevention, mitigation, and enforcement, with global initiatives based on global partnerships on marine litter providing strategic frameworks.Preventing plastic pollution through a life-cycle approach, focusing on lowering plastic manufacturing and consumption, and investing in research and monitoring programs are vital for developing effective strategies for plastic pollution management. Governments and organizations should allocate resources to improve monitoring capabilities and expedite the global policy-making process, promoting innovative recycling technologies and alternative materials to support the circular economy.In conclusion, addressing marine plastic pollution requires a multifaceted approach that combines monitoring, comprehensive assessment, and the development of robust policies to create sustainable solutions.
