Abstract

Blue carbon strategies are now being proposed as a promising, nature-based solution for achieving multiple benefits. Here we provide field evidence on the co-accumulation of organic carbon and neurotoxic mercury (Hg) in coastal environments. We estimate the global Hg stock in the top metre of sediment of blue carbon ecosystems to be 21,306 to 125,018 Mg (mean = 73,162 Mg), highlighting that Blue Hg stock is an important, dynamic, reactive, but overlooked Hg pool in global Hg cycle and health risk. Preserving and expanding blue carbon ecosystems have been hailed as a climate-friendly nature-based solution to store carbon. However, this can cause co-accumulation of neurotoxic mercury, highlighting the need for holistic climate solutions.

全球基于自然的蓝碳解决方案中神经毒性汞风险的潜在增加

蓝碳战略现在被认为是一种很有前途的、基于自然的解决方案，可以实现多重效益。在这里，我们提供了沿海环境中有机碳和神经毒性汞（Hg）共同积累的实地证据。我们估计蓝碳生态系统表层沉积物中全球汞储量为21,306 ~ 125,018 Mg（平均= 73,162 Mg），强调蓝汞储量是全球汞循环和健康风险中一个重要的、动态的、反应性的、但被忽视的汞库。保护和扩大蓝碳生态系统被誉为一种基于自然的气候友好型碳储存解决方案。然而，这可能导致神经毒性汞的共同积累，凸显了整体气候解决方案的必要性。
