Unraveling the oxidative geochemistry of nanoparticulate mackinawite in acid sulfate soil landscapes

酸性硫酸盐土壤影响了澳大利亚超过800万公顷的宝贵沿海土地，以及全世界超过2400万公顷的土地。酸性硫酸盐土壤水道的排水是对水质、生态系统健康、农业可持续性和渔业生产力的重大威胁。该项目的实际效益来自于更好地了解控制这些地区的水质和相关资源的过程。智力上的好处包括发展新的地球化学概念，涉及沿海河流、湿地和河口的中心硫磺矿物。该项目将加强澳大利亚的可持续环境管理能力。

Acid sulfate soils impact over 8 million ha of valuable coastal land in Australia, and over 24 million ha throughout the world. Drainage from acid sulfate soil waterways is a major threat to water quality, ecosystem health, agricultural sustainability and fisheries productivity. The practical benefits of this project arise from an improved understanding of the processes controlling water quality and associated resources in these areas. The intellectual benefits include the development of novel geochemical concepts involving sulfur minerals that are central to coastal rivers, wetlands and estuaries. This project will enhance Australia's capacity for sustainable environmental management.
