Natural Halogenation Processes in the Environment Atmosphere and Soil (HALOPROC)
DFG (ZE792/5-1)
From 04/2008 to 12/2016Principal Investigator: Cornelius Zetzsch
Staff: Johannes Ofner, Natalja Balzer, Sergej Bleicher, Julian Wittmer
Naturally produced halogen compounds are the central subject of our research unit. Produced in, and released from soils, salt surfaces, and aerosols, they are of utmost importance for stratospheric and tropospheric chemistry. The reaction mechanisms prevailing in natural halogenation processes in soil and on aerosols are similar from the viewpoint of reaction products, pointing to a chemistry where free radicals are involved.
