Persistent organic pollutants (POPs) are characterized by certain toxic properties which include resistance to degradation in the environment, bioaccumulation across food chains and long-range transportation though air, water currents or migratory species (United Nations Environment Programme [UNEP] and Secretariat of the Stockholm Convention 2017). This report addresses activities and results in support of the global monitoring plan (GMP) as stipulated by the Stockholm Convention on POPs and coordinated by the United Nations Environment Programme (UNEP). The report covers the period of the UNEP/GEF GMP2 project implemented in seven countries in the Asian region between 2016 and 2021 (UNEP 2015a); it does not include the Pacific Islands region, which had a self-standing project and final regional report (UNEP 2015b; UNEP 2024a).
