This report summarizes the results of chemical analyses of individual cases of precipitation sampled at different locations. The locations showed a great variety with respect to altitude, climate and level of industrial and anthropogeneous pollution. Furthermore detailed analyses and continuous records of the trace-substance concentration during individual rainfalls are discussed. The variations of the concentration during the course of the rain and their relations to quantity, intensity and types of rain as well as to meteorological parameters, are discussed. Finally, preliminary studies on the incorporation of trace-substances into cloud- and rain-drops are presented, indicating the relative importance of rainout compared to washout.
