Extensive data of physicochemical properties of precursors and products of aromatic nitro compounds important for the atmosphere

The overall aim is to study tropospheric formation processes of nitroaromatic compounds, which have been identified in field measurements of cloud, and rain water and some of which are know to be toxic and mutagenic.

To reach this aim, laboratory experiments on uptake and gas- and aqueous phase transformation mechanisms are performed and combined with field studies involving hyphenated analytical techniques. In particular several points were investigated:

-The uptake of polar aromatics by aqueous solutions.

-Nitration reactions with NO(3) radicals and nitronium ions in the aqueous phase and their products (in addition, OH-initiated nitration was studied in gas- and aqueous phase and nitration by NO(2) in the aqueous phase. Furthermore, major loss processes in the aqueous phase-such as photolysis and reaction with OH).
