Project
Within the AquaTRAIN network I'm working on the following topics:
• Developing a chemo-trapping method with nitric acid (HNO3) for volatile Se species (DMSe and DMDSe), which preserves speciation of trapped compounds as oxidized derivatives.
• Planning the application of the volatile Se trapping method in environments characterized by high Se contents.
• Studying the incorporation of arsenic in natural calcites from an arsenic-rich geothermal area in Chalkidiki (Northern Greece).
