Transformations in the form and reactivity of iron oxides in oxic and anoxic aqueous environments are considerably more dynamic than previously thought. This project will examine the nature and extent of these transformations and elucidate their impact on supply of iron to organisms and mobility of uranium and arsenic in groundwaters.

在有氧和无氧的水环境中，氧化铁的形态和反应性的变化比以前认为的要动态得多。该项目将审查这些转变的性质和程度，并阐明它们对向生物体供应铁以及地下水中铀和砷的流动性的影响。
