Over 100 nations signed the to control the adverse effects of mercury (Hg) emissions on human beings. A spatially explicit analysis is needed to identify the specific sources and distribution of Hg-related health impacts. This study maps China's Hg-related health impacts and global supply chain drivers (i.e., global final consumers and primary suppliers) at a high spatial resolution. Here we show significant spatial heterogeneity in hotspots of China's Hg-related health impacts. Approximately 1% of the land area holds only 40% of the Chinese population but nearly 70% of the fatal heart attack deaths in China. Moreover, approximately 3% of the land area holds nearly 60% of the population but 70% of the intelligence quotient (IQ) decrements. The distribution of hotspots of China's Hg-related health impacts and global supply chain drivers are influenced by various factors including population, economy, transportation, resources, and dietary intake habits. These spatially explicit hotspots can support more effective policies in various stages of the global supply chains and more effective international cooperation to reduce Hg-related health impacts. This can facilitate the successful implementation of the .
超过 100 个国家签署了《水俣公约》，以控制汞 (Hg) 排放对人类的不利影响。需要进行空间明确的分析，以确定与汞相关的健康影响的具体来源和分布。本研究以高空间分辨率绘制了中国与汞相关的健康影响及其全球供应链驱动因素（即全球最终消费者和主要供应商）的地图。在这里，我们展示了中国与汞相关的健康影响热点地区的显著空间异质性。大约 1%的土地面积仅容纳了 40%的中国人口，但却承载了中国近 70%的致命性心脏病死亡病例。此外，大约 3%的土地面积容纳了近 60%的人口，但却导致了 70%的智商（IQ）下降。中国与汞相关的健康影响热点地区和全球供应链驱动因素的分布受到多种因素的影响，包括人口、经济、交通、资源和饮食摄入习惯。这些空间明确的热点地区可以支持在全球供应链的各个阶段制定更有效的政策，以及更有效的国际合作，以减少与汞相关的健康影响。这有助于成功实施《水俣公约》。
