近日，大湾区城市环境安全与绿色发展教育部重点实验室学术带头人梁赛教授团队和华东师范大学地理科学学院陈龙研究员团队合作在环境领域顶级期刊《Environmental Science & Technology》上发表了题为“Looping Mercury Cycle in Global Environmental-Economic System Modeling”的评论性综述文章。在以往研究的基础之上，研究团队全面综述了全球环境-经济系统建模中汞循环各环节的研究进展，指出目前在环境-经济系统建模中的汞循环尚未闭合，难以揭示汞相关环境影响（包括人类健康影响和生态系统影响）对经济系统的反馈机制。鉴于此，本文提出了闭合汞循环的科学意义以及现有研究在汞循环闭合中存在的局限性，重点阐释了闭合汞循环建模的原理和途径。闭合汞循环将有助于制定动态的、灵活的汞污染控制措施，为《关于汞的水俣公约》的顺利实施提供新视角。

《水俣公约》针对汞的整个生命周期提出汞控制要求，以保护环境和人类免受汞污染的不利影响。现有的对全球环境-经济系统中汞循环的研究已经描述了汞污染从排放到影响的路径，即经济系统中的汞排放会对人类健康和生态系统产生不利影响。然而，目前对全球汞循环的建模并未完全闭合，忽视了汞相关的环境影响（包括人类健康影响和生态系统影响）对经济系统的反馈，从而阻碍了更全面的汞控制措施的制定。本文通过整合近年来汞循环建模的相关研究发现，汞相关的环境影响将通过劳动力可用性下降和生物多样性丧失对经济系统产生反馈作用。然而，环境和经济系统中汞相关过程之间的相互作用尚未明晰，汞相关的环境影响通过全球供应链对经济系统的级联效应尚未得到揭示。本文强调了该局限性，并提出了在全球环境-经济系统建模中闭合汞循环的可能途径。这一进展对于制定更加动态灵活的汞控制措施至关重要，为《水俣公约》的顺利实施提供了新的视角。

英文摘要：

The Minamata Convention on Mercury calls for Hg control actions to protect the environment and human beings from the adverse impacts of Hg pollution. It aims at the entire life cycle of Hg. Existing studies on the Hg cycle in the global environmental–economic system have characterized the emission-to-impact pathway of Hg pollution. That is, Hg emissions/releases from the economic system can have adverse impacts on human health and ecosystems. However, current modeling of the Hg cycle is not fully looped. It ignores the feedback of Hg-related environmental impacts (including human health impacts and ecosystem impacts) to the economic system. This would impede the development of more comprehensive Hg control actions. By synthesizing recent information on Hg cycle modeling, this critical review found that Hg-related environmental impacts would have feedbacks to the economic system via the labor force and biodiversity loss. However, the interactions between Hg-related activities in the environmental and economic systems are not completely clear. The cascading effects of Hg-related environmental impacts to the economic system throughout global supply chains have not been revealed. Here, we emphasize the knowledge gaps and propose possible approaches for looping the Hg cycle in global environmental–economic system modeling. This progress is crucial for formulating more dynamic and flexible Hg control measures. It provides new perspectives for the implementation of the Minamata Convention on Mercury.
