Enhancing the national capacity for monitoring persistent organic pollutants (POPs) among member Parties of the Stockholm Convention is a critical strategy to promote the global monitoring plan for POPs. This strategy can help identify changes in POPs concentrations over time and their regional and global environmental transport. To achieve this goal, the GEF project "Continuing Regional Support for POPs Global Monitoring Plan under the Stockholm Convention" has been implemented by the BCRC/SCRC China in the Asia Pacific region. As part of this project, a series of capacity building activities have been conducted, including disseminating a questionnaire on POPs monitoring capacity among regional countries, organizing forums to discuss the current situation and emergent needs in these countries, providing guidance on developing national monitoring plans, and identifying assistance from the Regional Centre, among others. These activities have enabled a clear understanding of the situation and difficulties related to POPs monitoring and have provided technical support to improve the national capacity for sustainable monitoring of POPs in these countries.
