| Outline of Final Research Achievements |
Mercury distribution balance was calculated for 231 countries/regions from 1995 through 2018. Thirty-nine small-scale gold mining (ASGM) implementing countries were listed, and the amount of mercury used for ASGM purposes was estimated from 2010 to 2018. The status of ratification and accession to the Minamata Convention and submission of National Action Plans for those countries were collected.
Based on the above, a method to detect and determine inappropriate mercury trade through ASGM-implementing countries was developed and applied to ASGM countries in 2010-2018. The presence of inappropriate trade was suggested in some countries/regions. The results were published in six international conference presentations and two international academic journals. Beyond the objectives, we hosted an international academic conference, provided the results to the Secretariat of the Minamata Convention and the Ministry of the Environment, and created content for disseminating research results.

| Academic Significance and Societal Importance of the Research Achievements |
学術的意義は、本手法により不適切な水銀貿易の検出・判定が可能である。手法開発の過程でより詳細な水銀排出量を含むASGMの「採掘活動量」に関わるデータベースを使用することが可能である。また、国際学会の開催により、水銀の課題に関する議論の場を提供することが出来た。
社会的意義は、水銀流通の把握や水銀管理の改善に役立てることが可能である。また、水俣条約事務局等で作成を進める報告書への知見を提供できた。そして、水銀に関する問題や課題をわかりやすく伝える情報発信用コンテンツを作成できた。
