Dr. Lars Duester

Ehemaliger Wissenschaftlicher Mitarbeiter (Umwelt- und Bodenchemie)


Since June 2008, Lars Duester is part of the Environmental Chemistry workgroup at the University of Koblenz-Landau. Former employer were the University of Duisburg-Essen, workgroup Prof. A. V. Hirner and the workgroup of Prof. Tim Mansfeldt, department of geography at the University of Cologne.

Research interests

The fate of metal(loid)s either released on natural basis or from anthropogenic causes is my key interest. Environmental matrices like soils, sediments, slurries, plants, waste or blood the borders zones between particles/colloids dissolved metal(loid)s (Ag, Cu, Sb, Sn, Ti, Zn), the transitions between the different organic/inorganic chemical species (As, Bi, Hg, Sb, Sn, Te) as well as the analytical method development are in the focus of my work.
