Research interests / background:

Salirian's thesis "Geochemical partitioning of iron and trace elements in acid sulfate soils" is due to be completed early 2011. The main purpose of the research is to better understand trace metal movement in ASS landscapes. To do this, a sequential extraction procedure was developed and optimised for iron, which is a major geochemical controller on trace metal movement in the landscape. This was then applied to a range of ASS materials, to determine re-partitioning of trace elements under a range of conditions, including oxidising and acidifying, as well as reducing and near neutral.
