A significant number of papers on the occurrence of a variety of organic and inorganic chemical species in the atmosphere have been published in the last two decades (e.g. Munger et al., 1984; Delmelle et al., 2001; Poschl et al., 2001; Warneke et al., 2001) indicating the complexity, previously unexpected, of atmospheric chemistry and the still growing need to extend the fundamental knowledge in this area. The situation gained even more drastic expression when the initially neglected input of atmospheric water (cloud droplets, falling raindrops, fog) to the chemistry of the atmosphere was realised. Although clouds makeup only a 5 percent volume fraction in the total troposphere and droplets in a cloud only one per ten million to one per million of its volume (Dentener et al., 1994), the atmosphere aqueous phase should be treated as an accumulation of myriad of minute but efficient reactors where many chemical reactions take place at concentrations of reactants usually much higher than in the atmosphere gas phase (Table 1). The aim of this paper is to discuss some less common, but not less important, directions of facing the phenomena resulting from the chemical complexity of the atmosphere, as seen from the laboratory experimentation perspective.
