Air monitoring activities are implemented in the five UN regions in cooperation with strategic partners: the Arctic Monitoring and Assessment Programme (AMAP), the Global Atmospheric Passive Sampling (GAPS) Network, the East Asia Air Monitoring Programme, the European Monitoring and Evaluation Programme (EMEP), the Integrated Atmospheric Deposition Network (IADN), the Great Lakes Basin Monitoring programme, and the MONET Programme of the Research Centre for Toxic Compounds in the Environment (RECETOX). Thanks are also extended to those involved in maintaining the sampling sites and collecting the samples at the national level. Further, the contribution of the projects to support POPs monitoring activities in regions, funded through the Global Environment Facility (GEF) and the Strategic Approach to International Chemicals Management (SAICM), is greatly acknowledged. The human milk survey draws on the collaboration between the Secretariat of the Stockholm Convention, the United Nations Environment Programme (UNEP) Division of Technology, Industry and Economics (DTIE) Chemicals Branch and the World Health Organization (WHO). The State Institute for Chemical and Veterinary Analysis of Food (CVUA), Freiburg, Germany, is acknowledged for the analytical work related to human milk samples. The MTM Research Centre, Örebro University, Sweden, is acknowledged for the analysis and provision of data on perfluorinated chemicals in human milk. Thanks are also expressed to the national coordinators of the joint WHO/UNEP exposure study for the work to collect and process the human milk samples. The following experts are gratefully acknowledged for having contributed to the development of this report: Mr. Tom Harner (Canada), Ms. Hayley Hung (Canada), Mr. Derek Muir (Canada), Mr. Minghui Zheng (China), Mr. Rigoberto Blanco (Costa Rica), Ms. Katerina Sebkova (Czech Republic), Mr. Vincent Madadi (Kenya), Mr. Yasuyuki Shibata (Japan), Mr. Alexei Gusev (Russian Federation), Mr. Ramon Guardans (Spain), Ms. Heidelore Fiedler (Sweden),Ms. Britta Hedlund (Sweden), Mr. Matthew MacLeod (Sweden), Mr. Henry Wöhrnschimmel (Switzerland) and Mr. Recep Kaya Göktaş(Turkey). Model simulations and data analysis leading to the development of the chapter on long range transport were carried out with financial support from the European Union 7th Framework Project ArcRisk, the Swedish Research Council FORMAS (project number 216-2011-427), and the Swedish Research Council Vetenskapsrådet (project number 621-2011-3921). The document was reviewed by the members of the global coordination group for the global monitoring plan, including, in addition to names acknowledged above: Ms. Anahit Aleksandryan (Armenia), Ms. Sara Broomhall (Australia), Ms. Trecia David (Guyana), Mr. W. Bharat Singh (India), Mr. Trajce Stafilov (Former Yugoslav Republic of Macedonia), Ms. Halimatou KoneEsp Traore (Mali), Mr. Otmani Anas (Morocco), Ms. Alejandra Torre (Uruguay). The support from Stockholm Convention Secretariat technical staff for the production of the draft is also gratefully acknowledged. 5 UNEP/POPS/COP.8/INF/38 PREFACE Persistent organic pollutants (POPs) are a group of chemicals that have toxic properties, resist degradation in the environment, bioaccumulate through food chains and are transported long distances through moving air masses, water currents and migratory species, within and across national boundaries. POPs belong to three main groups, however some of the chemicals fit into more than one of these three general categories: pesticides used in agricultural or public health applications1; industrial chemicals used in various applications2; chemicals generated unintentionally as a result of incomplete combustion and/or chemical reactions3. Twelve POPs were initially listed in the Stockholm Convention (shown in bold font in footnotes 1-3). In general, these ‘legacy’ POPs were first produced and/or used several decades ago, their persistence, bioaccumulative properties and potential for long-range transport are well studied, and they have been globally banned or restricted since 2004. In 2009, nine more substances were added to the Convention (chemicals with one asterisk in footnotes 1-3). Two additional chemicals were listed in 2011 and in 2013 (two or three asterisks in footnotes 1-3, respectively).POPs listed at the seventh meeting of the Conference of the Parties in 2015 are not yet addressed in this report. Article 16 of the Stockholm Convention requires the Conference of the Parties to evaluate periodically whether the Convention is an effective tool in achieving the objective of protecting human health and the environment from POPs. This evaluation is to be based on comparable and consistent monitoring data on the presence of POPs in the environment and in humans, as well as on information from the national reports under Article 15 and non-compliance information under Article 17. The global monitoring plan for POPs, which has been put in place under the Convention, is a key component of the effectiveness evaluation and provides a harmonized framework to identify changes in concentrations of POPs over time, as well as information on their regional and global environmental transport. The present global monitoring report synthesizes information from the first (2000-2008) and second (2009-2015) phase of the global
