Schwertmannite in acid sulfate soil landscapes: iron cycling induced acidification

硫酸酸性土壤影响了全世界超过2400万公顷的土地，仅在澳大利亚就影响了400万公顷的宝贵沿海土地。它们的氧化和酸化是导致水质、水生栖息地、农业生产力和城市基础设施灾难性下降的原因。该项目的实际效益来自于对这些地区控制酸化和水质的过程的更好理解。智力利益包括开发和应用与受酸性影响的沿海河流、湿地和河口有关的铁矿物的新的地球化学概念；该项目将提高澳大利亚可持续环境管理的能力。

Acid sulfate soils impact over 24 million ha of land throughout the world, 4 million ha of valuable coastal land in Australia alone. Their oxidation and acidification are the cause of catastrophic declines in water quality, aquatic habitat, agricultural productivity and urban infrastructure. The practical benefits of this project arise from an improved understanding of the processes controlling acidification and water quality in these areas. Intellectual benefits include the development and application of novel geochemical concepts involving iron minerals relevant to acidity impacted coastal rivers, wetlands and estuaries; this project will enhance Australia's capacity for sustainable environmental management.
