DESCRIPTION:Consequences of climate-induced redox oscillations on iron\, su
 lfur\, and contaminant geochemistry in freshwater re-flooded acid sulfate 
 soil wetlands.\n&nbsp\;\n\n\n\n\nDr. Niloofar Karimian\nFaculty of Science
  and Engineering\nSouthern Cross University\, Lismore\, Australia\n\n\n\n
 \n\n&nbsp\;\n&nbsp\;\n&nbsp\;\nA complex interplay between hydrology\, red
 ox conditions and iron (Fe) and sulfur (S) mineralogy leads to diverse rea
 ctions that determine the geochemical behaviour of contaminants and water 
 quality in acid sulfate soil (ASS) wetlands. Acid sulfate soils are soils 
 and sediments containing elevated concentrations of Fe sulfides or reactio
 n products resulting from oxidation of these sulfidic materials (e.g. acid
 ity and secondary Fe(III)-containing minerals). Many of the iron minerals 
 that commonly occur in ASS environments are both metastable and capable of
  being potent scavengers for toxic trace metals and metalloids under oxidi
 sing acidic conditions. Some trace metals and metalloids (such as arsenic 
 (As) and antimony (Sb)) may have a large impact on environmental quality. 
 Therefore\, a sound understanding of metastable host-mineral phases and th
 e corresponding behaviour of associated trace metal/metalloid contaminants
  under fluctuating redox conditions is essential for ASS wetlands manageme
 nt.\nThis talk will present some novel aspects of the geochemical cycling 
 of Fe\, S and trace metal/metalloids (with the specific focus on As and Sb
 ) in freshwater re-flooded ASS wetlands using a wide range of advanced ana
 lytical techniques including X-ray absorption spectroscopy (XAS). A major 
 focus will be made on improving our understanding of the potential effects
  of seasonal redox oscillations on Fe and S mineralogy in these wetlands a
 nd exploring the consequences for mobility and speciation of As and Sb. Th
 ere is a need for improved interpretation of the important processes and p
 athways\, which are likely to occur in conditions relevant to ASS environm
 ental settings under fluctuating redox conditions in order to better predi
 ct prospective environmental outcomes and choose optimal management strate
 gies.
