Mercury (Hg) bioaccumulation in Hg-polluted farmlands poses high health risk for humans and wildlife, and remediation work is urgently needed. Here, we first summarize some specific findings related to the environmental process of Hg in Hg-polluted farmlands, and distinguish the main achievements and deficiencies of available remediation strategies in recent studies. Results demonstrate that farmland is a sensitive area with vibrant Hg biogeochemistry. Current remediation methods are relatively hysteretic whether in mechanism understanding or field application, and deficient for large-scale Hg-polluted farmlands in view of safety, efficiency, sustainability, and cost-effectiveness. New perspectives including environment-friendly functional materials, assisted phytoremediation and agronomic regulations are worthy of further study as their key roles in reducing Hg exposure risk and protecting agricultural sustainability.

汞污染农田中的汞 (Hg) 生物蓄积对人类和野生动物的健康构成了高风险，亟需开展整治工作。在这里，我们首先总结了一些与汞污染农田中汞的环境过程相关的具体发现，并区分了近期研究中可用修复策略的主要成就和不足。结果表明，农田是一个充满活力的汞生物地球化学的敏感区域。目前的修复方法无论是机理理解还是现场应用都相对滞后，对于大规模汞污染农田在安全性、效率、可持续性和成本效益方面存在不足。包括环保功能材料在内的新观点，
