Abstract

Artificially generated NaCl particles were coated with PAH’s by using a condensation technique. These particles were exposed to reactive gases like ozone, bromine and nitrogen dioxide. The original as well as the exposed particles were investigated by fluorimetric analysis and by LAMMA (Laser Microprobe Mass Analysis) in the desorption mode, which allows the evaporation and characterization of surfaces of single particles. The results are interpreted in terms of possible heterogeneous atmospheric reactions. The reactivity of the considered PAH’s towards nitrogen dioxide was found to be negligible. The structure of the reaction products formed with ozone was partially elucidated.
