Abstract
Several procedures in nature and technology generate gaseous sulfuric acid, being the most important aerosol precursor gas. This was detected for the first time in atmospheric high voltage discharges. Moreover, comparative measurements of gaseous sulfuric acid and further trace gases emerging in high voltage atmospheric discharges were undertaken. Particularly the formation of the trace gases sulfuric and nitric acid was compared here. Another part of this work deals with the formation of gaseous sulfuric acid in the exhaust of a modern truck diesel engine with exhaust aftertreatment. For the measurement of gaseous sulfuric acid the chemical Ionization Mass Spectrometry that was developed by our group was applied in both cases.
