新污染物国际协同治理的演进趋势与启示OA

[Objective]With the accelerating global industrialization and the increasingly extensive application scenarios of chemicals,the potential risks of emerging contaminants to the ecological environment and human health have become increasingly prominent.It is urgent to clarify the overall pattern and development context of global emerging contaminants governance,so as to provide theoretical support and practical reference for relevant governance work.[Methods]Based on the WTO notifications data of technical trade measures from 2000 to 2025,this paper systematically sorts out the mechanism evolution and development trends of global collaborative governance of emerging contaminants from the dimensions of the country distribution of notifications,the evolution of regulatory content,and the scope of covered products.[Results]The research shows that developed countries have continuously played a leading role in legislation and standard development,while emerging economies are accelerating their follow-up;the focus of regulation has expanded from traditional pollutants to new chemical substances;the scope of covered products has extended from industrial products to consumer goods.In terms of collaborative governance,it exhibits characteristics such as multi-stakeholder co-governance,closed-loop prevention and control throughout the entire lifecycle,as well as refined and digitized governance approaches.[Conclusion]This study can provide reference for the optimization and improvement of China's emerging contaminants governance system.
