Using exciting new experiments and innovative analyses, this project will provide transformational insights into how sulfur cycling in the Earth’s critical zone affects arsenic speciation and fate. The project will resolve, for the first time, unexplored interactions between arsenic geochemistry and the low-temperature formation and transformation of metastable iron sulfide minerals. The outcomes will provide crucially important new perspectives on arsenic geochemistry in anoxic soils, sediments and groundwater systems.

利用令人兴奋的新实验和创新分析，该项目将为地球关键区域的硫循环如何影响砷的形态和命运提供变革性的见解。该项目将首次解决砷地球化学与亚稳硫化铁矿物的低温形成和转化之间未探索的相互作用。研究结果将为缺氧土壤、沉积物和地下水系统中砷的地球化学研究提供至关重要的新视角。
