Abstract : This report summarizes the results of detailed investigations in the laboratory on washout and rainout of SO2 by droplets of known size distribution and concentration. The results show clearly the effect of drop size, intensity and of the chemical composition (pH-value) of raing and fog on the scavenging efficiency. The results of the experiments were used as basis of a model calculation of the effect of washout and rainout by natural precipitation at a given vertical distribution of SO2. The report demonstrated under which circumstances the rainout, respectively washout mechanism becomes predominant for the chemical composition of rainwater at the ground. (Author)
