Natural Halogenation Processes in the Environment Atmosphere and Soil (HALOPROC)

DFG (ZE792/5-1)

Von 04/2008 bis 12/2016

Projektleiter: Cornelius Zetzsch
Mitarbeiter: 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.
