汞（Hg）暴露对人类健康构成重大风险。研究从经济活动到人类健康的更长链条，可以揭示汞相关健康风险的来源和关键过程。因此，我们开发了一个更全面的评估方法，适用于中国大陆-全球最大的汞排放国。我们提供了一个中国汞相关健康风险的地图，并估计2010年每个胎儿智商（IQ）下降0.14点和7，360例致命心脏病发作死亡与甲基汞的摄入有关。该研究首次揭示了省际贸易对全国汞相关健康风险的显著影响。例如，由最终消费引发的省际贸易使每个胎儿的智商降低了0.39 × 10− 2个百分点，并使194人死于致命的心脏病发作。这些研究结果强调了在经济供应链的不同阶段做出政策决定以减少与汞有关的健康风险的重要性。
Mercury (Hg) exposure poses substantial risks to human health. Investigating a longer chain from economic activities to human health can reveal the sources and critical processes of Hg-related health risks. Thus, we develop a more comprehensive assessment method which is applied to mainland China—the largest global Hg emitter. We present a map of Hg-related health risks in China and estimate that 0.14 points of per-foetus intelligence quotient (IQ) decrements and 7,360 deaths from fatal heart attacks are related to the intake of methylmercury in 2010. This study, for the first time, reveals the significant impacts of interprovincial trade on Hg-related health risks across the whole country. For instance, interprovincial trade induced by final consumption prevents 0.39 × 10−2points for per-foetus IQ decrements and 194 deaths from fatal heart attacks. These findings highlight the importance of policy decisions in different stages of economic supply chains to reduce Hg-related health risks.
