Resolving Critical Knowledge Gaps Relating to Light and Free-Radical Mediated Transformations of Iron and Copper in Oxic Natural Waters

了解铁和铜物种的转化动力学对维护澳大利亚的水资源至关重要，因为i）铁的转化是澳大利亚沿海环境中酸的产生和运输的关键; ii）富铁沉积物的溶解刺激有毒藻类的生长，随后释放营养物磷和铁，和iii）藻类毒性与铁和铜营养以及这些金属与氧的相互作用有关。此外，碳、磷和氮的全球循环受到铁和铜与光和氧相互作用的影响。对这些过程的进一步了解应有助于人们认识到如何预防这些问题，以及在出现问题时如何缓解这些问题。

Understanding the transformation kinetics of iron and copper species is critical to maintaining Australia's water resources since i) iron transformations are key to generation and transport of acid in Australia's coastal environment; ii) growth of toxic algae are stimulated by dissolution of iron-rich sediments with subsequent release of nutrients phosphorus and iron, and iii) algal toxicity is related to iron and copper nutrition and interplay of these metals with oxygen. Additionally, global cycles of carbon, phosphorus and nitrogen are influenced by iron and copper interactions with light and oxygen. Improved understanding of these processes should lead to an awareness of how to prevent these problems and, if they occur, approaches to their mitigation.
